When it concerns selecting guardian safety glasses, the possibilities can be limitless. You've sifted through many frames to find the ones that perfectly complement your style, only to be presented with a slew of lens coating options.
You don't have to be overwhelmed by all of the possibilities available. Understanding the fundamentals of popular lens coatings will help you feel more prepared for your next appointment. On the other hand, the eye care professionals on staff will be pleased to clarify their offers to you. Let's take a look at some popular and helpful lens coatings available.
Anti-Scratch Coating
There are no safety eyeglasses lenses completely scratch-resistant. Lenses that are treated with anti-scratch coating on both sides of lenses have a harder surface, making them more sensitive to scratching. Children's lenses, in particular, take advantage of scratch-resistant for increased durability.
Most eyewear lenses, particularly high-index lenses, Trivex, and polycarbonate lenses, now have a scratch-resistant coating built in. Because scratch-resistant coatings are not always required, inform your optometrist that you need eyeglass lenses with a hard coating for added durability. Inquire about the guarantee on scratch-resistant coated guardian glasses lenses compared to those that are not covered.
Keep in mind that even the strongest scratch-resistant coating will not protect your lenses fully from daily wear and tear. When not in use, you should place your eyeglasses in a protective pouch and clean the lenses with a microfiber cloth and the cleaning solution prescribed by your optometrist.
Also, avoid items that claim to restore scratched lenses. These treatments may fill in the scratches, but they cannot disappear scratches so that the lenses seem fresh again.
AR Or Anti-Reflect Coating
Anti-reflective coating (also known as AR coating or anti-glare coating) is a multi-layer microscopically thin coating that removes glare from the front and back faces of eyeglass lenses. AR coating keeps your lenses practically invisible, allowing people to focus on your eyes rather than annoying reflections from safety glasses.
Anti-reflective coating also removed glare generated by light. Lenses with AR coating minimize reflections, providing better vision for driving at night and better vision for computer use and reading. AR coating is highly recommended for all eyeglass lenses, but especially for high-index and polycarbonate lenses, which scatter more light than conventional glass or plastic lenses without anti-reflective coating.
Aspheric lenses come with flatter curves than conventional lenses and often produce more visible reflections, hence AR coating is also highly suggested for these lenses. When AR coating is applied to the back surface of lenses of guardian safety frames, it eliminates reflections when facing away from the light.
Eye care professionals typically suggest anti-reflective coating on photochromic lenses for the best comfort in any kind of lighting. AR coating increases the flow of light by the lenses for driving at night and lets photochromic lenses in reducing glare in direct sunshine.
Anti-Fog Coating
Nothing is more inconvenient than when your safety glasses fog up as you come in the cold particularly if you live in a chilly region. This can also be dangerous because it reduces vision clarity until the fog clears. Fogged lenses are highly hazardous to emergency responders and police officers.
Applying anti-fog coating on your safety glasses, your lenses, and eyesight will remain clear as you move from a cold to a warm environment. It may help prevent your glasses from fogging during games and other activities.
Fog Free can be used on polycarbonate, plastic, and other types of eyewear lenses as photochromic and high-index lenses. The anti-fog treatment is added to the lenses at the optical lab before they are trimmed for placement into your frame. Inquire with your local optical store about availability and cost.
UV Protection
An invisible coating that inhibits ultraviolet (UV) radiation is another beneficial lens treatment. Just like sunscreen protects your skin from the sun's UV rays, UV-protective coatings for guardian safety glasses lenses protect your eyes from those same rays. Ultraviolet light overexposure can lead to retinal damage, cataracts, and other eye issues.
Regular plastic eyeglasses lenses can also stop most ultraviolet light, but adding UV-coating increases protection to 100% for the best safety. Other eyeglass lens materials, such as high index and polycarbonate, offer built-in UV protection and do not require an additional lens treatment.
