According to the Vision Council of America, nearly 75 percent of the nation wears some type of vision correction device. Over 64 percent of those people wear eyeglasses on a daily basis to help them see clearly. Whether nearsighted or farsighted, people depend on their glasses to transform the way they see the world. The eyeglasses industry has responded by increasing their supply of prescription eyeglasses in order to meet the demands of eyeglass wearers across the nation. Although choosing frames may be one of the most exciting parts of purchasing new prescription eyeglasses, there are several other options when it comes to designing a new pair.
Lens Treatments and Eyeglass Coatings
Lens treatments and coatings can be added to lenses to increase their longevity and enhance the wearers comfort. Treatments are often built directly into the lenses during the manufacturing process or are bonded to the lens afterwards. Coatings are ultra-thin layers of material that are added to the surface of the lens. While some may think that lenses are simply prescription lenses, they may be surprised to find out all of the coatings and treatments that can be added to the lenses to enhance their functionality.
Ultraviolet Protection Treatment
There is no question that harmful UV rays can be destructive to eyes. The American Optometric Association reports show that long-term UV exposure can damage the retina and increase the chances of developing a cataract. Solar radiation can also cause conditions, such as macular degeneration. It is important to get a UV protection treatment on all eyeglass and sunglass lenses to ensure your eyes are protected from this harmful radiation. Make sure that the UV protection blocks out 100 percent of both UVA and UVB rays.
Anti-reflective technology has been used to add precision to cameras and microscopes for years. Now it is available to enhance the vision or eyeglass wearers. Anti-reflective lens treatments can add comfort to your eyes by reducing the glare from oncoming headlights, as well as other bright lights you may encounter.
The treatment works by blocking reflected light, which is responsible for causing glare and halos that appear around lights. Some eyeglass cleaners are not formulated to clean the delicate layers of anti-reflective treatment and may actually destroy the metal oxides. With anti-reflective treatments, it is important to only use cleaning agents that are recommended by an eyecare professional.
Getting a scratch on your eyeglasses may be unavoidable. However, with scratch-resistant coating, lenses can stay looking clearer for a longer period of time. Along with treating your lenses with scratch-resistant coating, there are several other ways to prevent your eyeglasses from getting scratched, including:
- Always keep your glasses in a sturdy, cushioned eyeglass case when they are not in use.
- Clean lenses routinely with warm, sudsy water.
- Always use a soft cloth to gently wipe lenses dry or clear off any smudges.
Outdoor enthusiasts, children, and light-sensitive eyeglass wearers can all benefit from photochromic lenses. The lenses remain clear while indoors, and then darken to protect eyes from sunlight outdoors. Often referred as transition lenses, these lenses are popular for any eyeglass wearer who wants to have their sunglasses and eyeglasses in one.
Before selecting a new pair of quality eyeglasses, it is important to understand all of the options that are available. You will be able to make a more informed decision, and know what to look for when creating a pair of custom eyeglasses.
