From the early days of purely glass lenses to the advanced materials we use now, the technology in prescription lenses is constantly improving.
Today, special lens coatings improve and protect our vision in ways we could only dream of before.
If you are thinking about purchasing new eyeglasses, here are lens coatings and treatments you should consider.
Anti-reflective Coating Eliminates Lens Reflections
Anti-reflective coating (also called AR coating or anti-glare coating) is a microscopically thin multilayer coating that eliminates reflections from the front and back surface of eyeglass lenses.
By doing so, AR coating makes your lenses nearly invisible so people can focus on your eyes, not distracting reflections from your eyeglasses.
Have you ever noticed a bright glare on a window pane or reflective surface? If present on your eyeglass lenses, reflected light can be both a distraction and a potentially dangerous obstruction to your vision. Anti-reflective coating can applied to block reflections from both the front and the rear surface of your lenses. With these reflections gone, you’ll be able to see more clearly and your lenses will look nearly invisible, allowing everyone to see your beautiful eyes!
With reflections eliminated, lenses with AR coating provide better vision for night driving and more comfortable vision for reading and computer use.
Some lens materials are manufactured with anti-reflective coating by default, while others must be applied afterward.
Also Antireflective coatings have not only be made to block reflections, they also help to eliminate the 5 enemies of clear vision which are:
- Glare which causes Eyestrain
- Smudge which causes Light diffusion
- Scratch which causes visual discomfort
- Dust which causes blur
- Water which causes distortion
Advanced Technology Protects Lenses From Scratches
Nothing is scratch-proof, but there are coatings to help make lenses more resistant to scratching. Lenses can be treated with a scratch-resistant coating to protect them from scuffs caused by all of life’s little mishaps. Children may especially benefit from such coatings as they are prone to accidents.
Even if your lenses have scratch-resistant coating, always be sure to maintain proper care for your glasses. Be sure to store them in a cushioned case when not in use, and always clean them with a microfiber cloth and a cleaning solution recommended by your Doctor.
UV Protection Isn’t Just For Sunglasses
We all understand how important UV protection is for our sunglasses, but this protection is just as important for our everyday lenses. Prolonged UV exposure can lead to a condition called photokeratitis—a sunburn on the eyes often called snow blindness— or have more serious consequences to our vision health including macular degeneration, retinal damage, or cataracts.
Many modern lenses are built with UV protection, but others require an additional coating to ensure 100 percent of UV rays are blocked.
Blue light emitted from the sun and electronic devices such as smartphones and computer screens also pose a threat to our vision health. Looking at screens for an extensive period of time can result in digital eye strain, causing vision fatigue and sometimes annoyances like eye twitching or red eyes.
While there are a number of things you can do to gain relief from digital eye strain, lenses are available that reduce the eye’s exposure to blue light. If you look at screens extensively for work or personal use, ask your optometrist if these lenses are right for you.
