COATINGS FOR EYEGLASS LENSES: SCRATCH-RESISTANT, ANTI-REFLECTIVE, AND UV-RESISTANT

Lens coatings, as we all know, can drastically improve the appearance of your eyeglass while also improving its performance. Those wishing to purchase a new pair of eyeglasses or who currently own a pair can now get new glasses with lens coatings. Anti-Reflective, Scratch-Resistant and Ultraviolet Rays are the three most important factors to consider when buying new sunglasses.

COATING WITH ANTI-REFLECTIVE PROPERTIES

Anti-reflective coating, often known as “AR coating,” is a thin multilayer coating on the front and back surfaces of lenses that greatly minimises reflections. The anti-reflective coating reduces the brightness created by light refracting off our lenses. Lenses with AR coating provide improved eyesight for driving and much more comfortable visualisation for reading and computer use while minimising reflection.

This is also strongly recommended for all lenses, but especially polycarbonate and high-index lenses, which reflect more light than glass or plastic lenses if AR coating is not applied. In addition, compared to ordinary lenses, these lenses have flatter edges, which are frequently the source of visible reflections. This is why AR coating is highly suggested for these types of lenses.

While you get AR coating for your prescription glasses, it helps to lessen or even eliminate reflections when you are gazing away from the sun. Consult your eye care provider about applying an anti-reflective coating to photochromic lenses if you want to achieve outstanding comfort in any lighting scenario.

COATING THAT IS SCRATCH-RESISTANT

Nothing in the world lasts forever, as we all know, and eyeglasses are no exception. As a result, depending on how one uses their lenses in their everyday routine, some or more scratches are likely to appear.

Keeping your lenses gleaming with a clean, scratch-resistant cloth with a softer, microfiber surface will last you much longer than using common paper tissues and paper towels. Depending on the material of your clothing, even your everyday wear can cause scratches.

People frequently order anti-scratch lenses for children since they know that children are rough on their eyewear and that using these coatings can help them live a little longer.

However, keep in mind that even the best scratch-resistant coating will not provide perfect protection, and you may see some wear and tear. Another simple and effective technique to extend the life of your eyeglasses is to store them in a protective case when not in use and wipe them with a microfiber cloth or any other recommended cleaning solution by your optician.

TREATMENT Via ULTRAVIOLET

Last but certainly not least on the list of lens coatings is Ultraviolet Coating, which is a mysterious pigment that prevents harmful rays from entering our eyes and eventually destroying them. These coatings work in a similar way to sunscreens in that they protect our eyes from harmful radiation.

Furthermore, the UV-protective properties of these lenses prevent the majority of rays from damaging your eyes. Cataracts, retinal damage, and other significant eye problems can all be caused by exposure to ultraviolet sunbeams.

Daily Acetate, TR90, and plastic prescription eyeglasses lenses block the majority of UV light while also increasing UV safety to 100% for added protection. Polycarbonate and some high-index lenses include incorporated UV protection that is 100 percent effective. This eliminates the need for an additional lens cure for these lenses. Photochromic lenses, on the other hand, can block 100 percent of UV rays from the sun without the need for additional UV lens treatment.
