Eyeglasses come with a variety of different coatings for protection from a range of problems. Knowing the difference between these kinds of coatings and which ones are best for your needs can help you have the best experience with your eyeglasses.
UV coating offers protection from the sun's harmful UV rays. Since UV rays can cause a variety of different types of damage to the eye, UV coating can actually help preserve your vision and keep you safe from harm while spending time out in the sun.
- Who benefits from UV coating on their lenses? People who wear standard plastic lenses and who spend time out in the sun will benefit from UV coating. People with light colored eyes are especially vulnerable to diseases caused by UV exposure and should definitely consider getting UV coating. In fact, the only people who really don't need to get UV coating for their glasses are people who have polycarbonate lenses, because these lenses automatically block UV rays without a special coating.
Scratch-resistant coating offers no guarantee that your glasses will never become scratched, however, scratch-resistant coating can help protect your lenses from much of the everyday wear and tear that your glasses may experience.
- Who benefits from scratch-resistant coating? Children, athletes and people who simply drop their glasses a lot will benefit. Anyone who is active, who takes off their glasses and sets them down in various places throughout the day, and people who don't make use of eyeglasses cases can also benefit from scratch-resistant coating.
Anti-fog coating does exactly what it says: it prevents your glasses from fogging up during rapid temperature changes. Foggy glasses will obscure your vision until they clear, which means that having an anti-fog coating can address an important safety concern.
- Who benefits from anti-fog coating? People who live in cold climates will benefit the most from anti-fog coating. Since anti-fog coating can prevent slips, trips and falls, this type of protection may be especially important for children, elderly people and anyone with problems walking safely.
Anti-reflective coating will eliminate reflection from your lenses, including reflections from computer screens and glare from oncoming headlights.
- Who benefits from anti-reflective coating? People who work in office settings and those who spend a lot of time driving at night (like truck drivers) may benefit most from anti-reflective coating. That said, nearly anyone living in a modern society who spends time in front of a computer and behind a wheel after dark can benefit from anti-reflective coating.
Choosing the right coatings for your lenses can improve your experience with your eyeglasses overall. For more information about the types of coatings available, talk to a local eye doctor (such as one from http://envisionnv.com/).
