    Single Vision Stock / Grind
    Single vision lenses are those that have the same focal power throughout the lens. They can be used to treat short-sightedness, far-sightedness or astigmatism.

    The conventional stock lenses provide sharp view at the center of the lens, with some distortion in the peripheral areas. The lenses are fitted to the particular wearer and optimised for clear vision. Stock lenses are available in restricted power range only and are limited to frame sizes. While these lenses can be ideal for people that are short-sighted (minus powers), we recommend grind lenses for people that are long-sighted (especially high plus powers), that result in a thinner and lighter product.

    Grind lenses are made with advanced optical design technology and are specially surfaced to the correct thickness for the dimensions of the frame. These lenses provide sharp view and minimal distortion in the peripheral areas. There are different lens technologies available to grind single vision lenses. Besides the standard grind lenses, CR Surfacing offers Digital and Digital Accuracy lens designs, that take single vision performance to the next level.

    For general purpose, everyday wear, we recommend using Satin UV Anti-Reflecting Coating. Our Satin UV Anti-reflective coating is developed to improve vision by reducing glare, eliminate eyestrain by enhanced visual performance, protect your eye health by blocking UV rays, and enhance cosmetic appearance by cancelling out reflections on the lens surface. This coating also helps extend the life of the lenses. The Satin UV coating consists of layers specially formulated to create a scratch-resistant, water and dust repellent coat, making the lenses last longer. An ideal solution for everyday use, no matter the environment.

    If you spend a lot of time on computers or digital devices, to give your eyes as much comfort as possible, we recommend to pair these lenses with Satin Blue coating. CR Surfacing’s special anti-reflective Satin Blue coating filters out harmful blue light coming from digital surfaces, as well as natural and artificial lights. Approximately one third of all visible light is blue light, a high-energy light that has a number of biological effects, including on the eye. Blue light penetrates all the way to the retina and can damage the light-sensitive cells and can increase the risk of age-related macular degeneration. Although not all blue light is bad, as it helps boost alertness, memory and cognitive function, the harmful wavelengths can be filtered out with Satin Blue coating, providing maximum comfort, enhanced visual performance and protection for your eyes.

    Progressive lenses and the advantages of having them
    Progressive lenses are no-line multifocal eyeglass lenses that look exactly the same as single vision lenses. In other words, progressive lenses will help you see clearly at all distances without those annoying (and age-defining) “bifocal lines” that are visible bifocals and trifocals.

    Progressive lenses are line-free multifocals that have a seamless progression of added magnifying power for intermediate and near vision.

    The power of progressive lenses changes gradually from point to point on the lens surface, providing the correct lens power for seeing objects clearly at virtually any distance.

    Bifocals, on the other hand, have only two lens powers — one for seeing distant objects clearly and a second power in the lower half of the lens for seeing clearly at a specified reading distance. The junction between these distinctly different power zones is defined by a visible “bifocal line” that cuts across the center of the lens.

    Progressive lenses sometimes are called “no-line bifocals” because they don’t have this visible bifocal line. They have a significantly more advanced multifocal design than bifocals or trifocals.

    Most people start needing multifocal eyeglasses sometime after age 40. This is when a normal aging change in the eye called presbyopia reduces our ability to see close objects clearly.

    Progressive lenses also are the lens of choice for anyone who needs corrective lenses to see distant objects clearly (due to nearsightedness, farsightedness and/or astigmatism) and for those who are presbyopic.

    For anyone with presbyopia, progressive lenses have significant visual and cosmetic benefits compared with traditional bifocals and trifocals.

    As already mentioned, bifocals have just two powers — one (in the top half of the lens) for distance vision, and a second (in the lower half of the lens) for near vision.

    Trifocals go one step further — they have a third power for seeing objects clearly at arm’s length. This “intermediate” power of a trifocal lens is located in a thin horizontal zone between the distance and near power zones.

    Progressive lenses, on the other hand, have many more lens powers than bifocals or trifocals, and there’s a gradual change in power from point to point across the surface of the lens.

    The multifocal design of progressive lenses offers these benefits:

    It provides clear vision at all distances (rather than at just two or three distinct viewing distances).

    It eliminates “image jump” caused by bifocals and trifocals. This is where objects abruptly change in clarity and apparent position when your eyes move across the visible lines in these lenses.

    Because there are no visible “bifocal lines” in progressive lenses, they give you a more youthful appearance than bifocals or trifocals. (This may be the reason why today more people wear progressive lenses than the bifocal and trifocals combined.)

    A professional optician can help you select the best progressive lens brand and design for your eyeglass prescription and your unique visual needs.

    Your optician can also give you helpful tips on how to quickly become accustomed to wearing your new progressive lenses and how to care for your eyeglasses to continue seeing clearly. Also, for the best clarity, comfort and protection in all lighting, ask your optician about adding anti-reflective coating and photochromic lens treatment to your new progressive lenses.

    Ready to start seeing better? It starts with an eye exam to update your prescription and then a visit to your eyewear retailer or shopping for glasses online.

    Check These Pros and Cons of Using Blue Cut Lenses Before Buying
    What are Anti-Glare Glasses and Why You Should Invest in Them?

    The benefits of blue light blocking glasses are numerous and varied. However, there are also a few blue cut lenses disadvantages. So let’s first start by knowing what blue cut lenses are?

    Digital screens like computers, smartphones, TV and interior lighting with LEDs emit blue light, which your eyes now absorb in excess. These blue lights are harmful to your eyes, thus creating a need to own a pair of blue light glasses. You can find the best blue light blocking glasses at Titan Eyeplus to ensure your eyes remain protected at all times.

    There are several health-related effects of blue light emitted from screens, such as:

    • During the day, you may experience visual tiredness;

    • At the end of the day, you’ll have headaches;

    • Having trouble falling asleep and having sleepless nights;

    • Retinal degeneration is more likely.

    • Increased vulnerability post-cataract surgery.

    Blue cut lenses block 40% of this hazardous light thanks to a filter added to these glasses. This filtration is more than enough to restore proper blue light levels reducing adverse effects. Wearing blue light filter glasses protects your eyes as well as your health!

    Simple Science: The Difference Between Soap and Detergent
    American consumers often use the words “soap” and “detergent” interchangeably, but in reality there are significant differences between these two types of cleaners.

    A Brief History

    The earliest evidence of soap can be traced back to 2800 B.C., where historians believe it was used by the ancient Babylonians. Soap making is mentioned in ancient Roman documents written as early as 70 A.D.

    Fast forward to Medieval Europe where soap making is an established craft with centers in France, Spain and Italy. During that time the use of soap was a luxury enjoyed mainly by those who could afford it. Manufactured bar soaps weren’t available until the late 18th century in Europe and the U.S. Widespread use of soap during this period can be attributed to advertising campaigns touting the relationship between good personal hygiene and health.

    Detergents entered the picture about 1916 when World War 1 soap ingredient shortages encouraged manufacturers to develop synthetic cleaners to meet demand. By the 1950s detergents had overtaken traditional soap products in homes across America. Today, detergents are used for laundering, dishwashing and many other types of cleaning.

    The Chemistry

    Soaps are made from natural ingredients, such as plant oils (coconut, vegetable, palm, pine) or acids derived from animal fat. Detergents, on the other hand, are synthetic, man-made derivatives. While soap is limited in its applications, detergents can be formulated to include other ingredients for all sorts of cleaning purposes. Perhaps the most common and versatile of these ingredients are surfactants … surface active agents.

    About Surfactants

    Surfactants aid in cleaning because they reduce surface tension and improve water’s ability to spread evenly over it. This creates a more uniform wetness that makes dirt and soil easier to wipe away and remove. Surfactant molecules can also have either a positive or negative charge, with one end attracted to water and the other end attracted to dirt and grease. This helps detergents attach to dirt, break it up and let water wash it away.

    Most cleaning products today are detergents. One of the biggest reasons for this is the way soap reacts with water. While detergents are free-rinsing (meaning they don’t leave a residue), soap needs a clear water wash after application or it will leave a film.

    Hard water is the enemy of soap. In hard water conditions soaps form scum. Soap scum affects more than just cleanliness; it can deteriorate fabrics and eventually ruin clothing or other surfaces. Conversely, detergents can work in any level of water hardness since they react less to the many minerals in hard water.

    Finally, soaps need warm water to work at all. Detergents, on the other hand, can be built to perform well in any water temperature. This versatility enables detergents to be used in everything from shampoo to laundry liquid to hand cleansers and stain removers.

    Powder Detergent
    Pros:

    Less messy than liquid detergent

    Tends to be cheaper per load than liquid or pods

    Generally more shelf-stable than liquid or pods, so it will last longer

    Has more eco-friendly packaging

    Amount of powder used per load is customizable

    Lightweight compared to liquid detergents

    Works well on heavily soiled clothes, such as sports uniforms

    Cons:

    Some powder detergents have trouble dissolving in colder water, which can leave residue on clothes

    Can be used for pretreating clothes, but you need to make a paste or dissolve it first, adding an additional step to your laundry routine

    Needs to be kept dry

    Messier than pods

    Best for

    Powder detergent is a smart pick for extra-dirty loads, says Mary Gagliardi, aka “Dr. Laundry,” Clorox’s in-house scientist and cleaning expert. “Powder detergent is usually formulated at a higher pH, which can optimize cleaning of heavily soiled work clothes and sports uniforms,” she says.

    Laura Johnson, a research and development expert with the LG Electronics home appliances lab, points to money- and environment-saving benefits. “Powder detergent is best for consumers who are looking for eco-friendlier packaging,” she says. “It’s also a better budget option for consumers.”

    Dishwasher Liquid vs. Dishwasher Detergent
    Clean Dishes

    Not only should you know the difference between dish soap and dishwashing detergent, you might also be interested in learning the difference between dishwasher liquid and dishwasher detergent.

    Dishwasher liquid is usually better able to mix with water, which can affect how wide the liquid can spread inside of your dishwasher. Dishwashing detergent doesn’t dissolve as well in water, which is why it’s often best that you use it with warm water. What this all boils down to is that the same amount of dishwasher liquid will need to be used in order to get the same cleaning ability as a dishwasher detergent.

    Another difference between dishwasher liquids and detergents is that liquids can sometimes stick to the inside of your dishwasher. You might notice signs of corrosion inside of your dishwasher if there is residue from dishwasher liquid inside of it. While these corrosion deposits are easy to scrape off, they aren’t always so easy to find.

    Now that you better understand the difference between dishwasher detergent and dish soap, make sure that you use caution the next time you reach for that random bottle with the sparking glass on it while washing dishes in the sink or in the dishwasher.

    Which Cleans Better? Liquid vs. Powder Detergent
    It’s a dirty job, but somebody’s got to do it! And if you’re the one on laundry duty, you’ll want some serious detergent to get those soiled clothes clean. With the help of water, and the rotation of the washer’s inner drum (in a front-load machine) or spindle-like agitator (in a top-load machine), detergent lifts dirt, stains, and odors away.

    But when it comes to cost, convenience, and cleaning power, not all detergents are equal. The two main types, powder and liquid, are suitable for use in standard or high-efficiency top-load or front-load washers at any water temperature. So which should you choose? Ahead, we break down their differences with six key comparisons—liquid vs. powder detergent—to help you decide which is best for your family’s laundry.

    Powder detergent is more effective on mud stains; liquid detergent is better on grease stains.

    Alkylbenzene sulfonate, the main surfactant (cleaning agent) in powder detergents such as Tide Original HE Turbo Powder ($12.95 per 95 oz. on Amazon), is generally more effective in lifting mud, grass, and bloodstains, which makes powder a great option for garden and athletic attire. In contrast, the alcohol ethoxylates in liquid detergents like Persil ProClean Power Original Liquid Detergent ($17.99 per 75 oz. on Amazon) easily break down grease stains from cooking oil to car grease, making liquid detergents a top choice for everyday wear.

    Benefits of OEM Volvo Parts
    OEM Volvo Parts: Making a Smart Investment in Your Vehicle

    When you buy a new Volvo, you’re not just buying a car. You’re buying pragmatic design, premium materials, and precise engineering. You’ll want to preserve that quality throughout your car’s life, and one of the best ways to do that is to use genuine OEM Volvo parts for all service and repairs.

    Volvo’s proprietary OEM parts and accessories are designed and built with the same dedication to quality as its cars. From model-specific batteries and brake pads to practical interior and exterior add-ons, these components serve a wide array of needs. And every one of them is held to high standards for durability, fit, and appearance.

    There are quite a few reasons to pick OEM parts for your Volvo, but it breaks down to one simple idea: it’s one of the best ways to help your vehicle reach its peak potential.

    Designed for a Perfect Fit

    First and foremost, Volvo designs its OEM parts to fit perfectly into their designated models. There’s no wiggle room or grey area — each part is engineered for a seamless integration into the systems of a specific Volvo model. Replacement parts are built to the exact specs as the original factory components, while add-on accessories are designed to fit in flawlessly. The result is parts and accessories that work well with the vehicle as a whole.

    Engineered for the Long Road

    You may be able to find some lower prices with off-brand parts, but you’ll likely make up for the cost with diminished quality. Volvo OEM parts, on the other hand, are built without compromise to durability. They’re meant to last longer and perform better than any of the aftermarket or off-brand alternatives.

    Compliant with Your Warranty

    If your Volvo is still within its warranty period, you’ll want to keep using OEM parts for the duration of coverage. Using certain off-brand components can end up voiding your warranty, since they don’t adhere to Volvo’s own standards for quality.

    How Do Water Tanks Work?
    Water tanks provide real water conservation benefits, for both people and the environment. They play an important role in preserving precious water, especially rainwater. However many still ask, how do water tanks work? Water tanks come in different sizes, shapes and types, but all the different tanks have certain similarities in how they work.

    People need lots of water every day for essential purposes like drinking and cleaning – but there is only a certain amount of water available. Sometimes water gets even scarcer, like when there is a drought and water restrictions come into effect. Rain water harvesting can ensure that people have water to meet their daily needs, and water tanks are an essential part of this. A water harvesting system can be installed in a house. When it rains the roof of the house becomes the water catchment area. The gutters on the roof funnel rainwater into the pipes, which connect the gutters to the water tanks. The water is then transported via pipes to the water tanks installed above or below the ground.

    The captured rainwater is then stored to be used around the house. The water can be used for a number of purposes like cooking, washing and gardening. In urban and suburban areas where town water is available, it is not recommended to drink rainwater. In rural areas it may be possible to drink harvested rainwater, but you will need to install a filtration system to do so. Water tanks may also play a role in storing water that is supplied by local authorities.

    Every home would benefit from having a water tank installed that is large enough to sustain the home for a considerable period of time, even if rain is scarce or the water supply from the local authorities stops. Depending on the property, a water tank can either be placed on the ground, below or even be elevated above the ground on a stand or platform. Above ground round polyethylene tanks are often the most cost effective option.

    How Mud Flaps Benefit Your Vehicle
    Mud Flaps – They Are Not Just for Aesthetic Purposes

    Work trucks entering the highway are many times the culprits responsible for leaving for gravel, mud and dirt caked onto the road. Not only can hitting these road debris fields affect your car, but it can have damaging effects to other cars around you. Whether you have a truck, van or SUV, adding Mud Flaps can help save you from irritating dings and dents to your vehicle.

    How Mud Flaps Benefit Your Vehicle

    Mud Flaps protect your vehicle by safely deflecting road debris away from the fender wells. Your tires are in constant contact with a long list of obstacles ranging from muddy water to thick tar on a daily basis. Fender wells are made to contain these elements, but need some additional help. Since your fender wells do not extend down behind the tires, debris can still be thrown to damage cars behind you and directly affect your vehicle with damage.

    When you install Mud Flaps, an additional barrier is created between the wheel well and the tire. Once the paint around your fender is penetrated, the potential of rust forming on the bare steel is quite real. The various road chemicals, oil, and dirt now have a place to adhere. The unsightly dents from rocks and paint chips could leave your car at the local body shop with costly repairs. In their simplest form, Splash Guards also keep the exterior of your vehicle looking cleaner by limiting water splatter.

    Dee Zee offers several styles of cost effective Mud Flaps to keep you safely on track to your next destination. You can make sure the design fits your lifestyle for worry free driving.

    Car Grille: What Are Its Functions?
    A car grille is a protective metal or plastic latticework or grating located on the front of your vehicle between both headlights. It is one of the auto parts that complete the face of a car. Sometimes, the grille bears the logo of the manufacturer.

    Most people see the car grille as just an aesthetic feature to enhance the vehicle’s appearance. In reality, it does that and more. I’ll try to bring this underrated accessory to limelight by stating three essential functions it performs. Just before I jump into it, there’s a common misconception over whether it is grill or grille. It’s grille (with an e). We’re not in the kitchen, alright? (wink)

    What Are the Functions of a Car Grille?

    1. Help in air circulation

    The grille covers the car’s front end yet allows air to get through its gaps. So, while it protects the engine from road debris, its ultimate function is help air circulation to the engine room. Air that’s allowed through the grille helps cool the moving components under the hood. Isn’t that what a radiator is for, you may wonder? In fact, it is. But the car grille performs an essential supportive role. The air that comes through the grille cools the temperature of the water in the radiator to avoid overheating. In short, the grille enables the radiator to perform optimally.

    2. Aid aerodynamics and performance

    The car grille’s design is often integrated into a vehicle’s aerodynamics, which enhances the car’s performance. Without an opening, air resistance would build-up against a car and impact on its speed. With a grille present, and one designed to optimally aid aerodynamics, air shifts smoothly through the grille, the side, and top of the vehicle, lessening the impact of air resistance significantly.

    Some automakers have even adopted a technology that automatically opens and closes the grille’s cavity as needed by the engine.

    3. Improve aesthetics

    The aesthetic benefit is undoubtedly the most apparent function of a car grille, although not the most important. Since we all care about beauty, it’s a function worthy of being mentioned.

    Virtually all car brands treat the grille as a part of the brand’s identity. Grilles are so unique and distinctive in their appearance that you can tell an approaching car by its grille. You’ve noticed too, right?

    Some auto manufacturers deliberately maintain the design of their grille because, over time, it has become an iconic thing for the brand. Others modify the car grille design more frequently but have the grilles carry their logo as part of their brand design.

    BMW, for instance, has had the same twin-oval design for several years, although she often revises them slightly for a new look. Consider Volvo too, for instance. Relative to other brands, she changes her grille design pretty often. But the grille still always has the brand logo or signature as an emblem.

    Is It Okay to Drive Without a Grille?
    Despite the advancements in engineering and technology, it is still impossible to have an internal combustion engine vehicle without a grille. The aesthetic and aerodynamics features could be overlooked. Without air passage, the cooling system won’t function at optimal capacity. Without a grating to cover air passage, you will put the vehicle at risk.

    But what if your car’s grille was removed for whatever reason, and you needed to hastily drive your car without it? In emergency cases, you may drive without car grille, because its absence does not block the air passage. That’s not to say that it’s okay, because it’s not advisable. You’ll need to check with transport laws if you’re allowed to drive without car grille. Also, with an unprotected front end, your car’s radiator and engine will be exposed to debris and wind.

    With the future rolling more and more toward electric cars—which have no need or less need for air cooling— we may be seeing more grille-less cars. And if we did see them, it’d be mostly for design purposes.
