After choosing frames and lenses for your new eyeglasses, it is important to decide whether a lens coating is a right choice for you. In recent years, many different types of lens coatings have been developed and introduced to the market.
Eyeglass lens coatings can enhance lens (and eye) performance and add to your new lenses' appearance. Here are seven different lens coatings you should consider when purchasing new eyeglasses.
UV exposure has been linked to age-related eye problems such as cataracts and macular degeneration. UVA and UVB-blocking lenses can help prevent the harmful effects of UV radiation.
UV protection coatings can be applied to both clear and sunglass lenses.
UV protection in sunglasses and fashion eyewear is not mandated, so UV protection can vary significantly between manufacturers. Choose sunglasses that clearly state they are made with a coating that provides 100% protection from UV-A and UV-B light to help ensure your eyes receive the protection they require. Ask your vision care provider what level of UVA/UVB protection is available with the lenses they offer.
An Anti-reflective coating, also known as AR or anti-glare coating, is a skinny multilayer coating that eliminates reflections from the front and back surfaces of lenses. This coating also reduces halos around light and gives your lenses a more excellent cosmetic appearance, making them nearly invisible. AR coating improves light transmission through the lens for night driving and helps photochromic lenses reduce glare in bright sunlight.
An AR coating benefits polycarbonate and high-index lenses, which reflect more light than standard glass or plastic lenses. This coating also works well for aspheric lenses, which have flatter curves than regular lenses, resulting in more noticeable reflections.
Eye care professionals recommend applying an anti-reflective coating to photochromatic lenses to ensure comfort in all lighting conditions. It increases light transmission through the lenses for night driving and decreases glare in direct sunlight.
Scratched lenses are distracting and can impair your ability to see clearly. Scratch-resistant coatings are now built into many eyeglass lenses, including high-index lenses and polycarbonate and Trivex lenses. These lenses have a much harder surface and are treated on both the front and back with a clear, scratch-resistant coating. A scratch-resistant hard coating protects the lenses of children.
This is the coating for you if you are looking for a purely cosmetic lens that allows the eyes to remain hidden from view.
These coatings are available in a variety of colors, densities and styles. They are popular in both prescription and non-prescription sunglasses. Mirror coatings can be applied as a solid, gradient and double gradient coating.
The most common mirror coatings are flash mirrors and half mirrors. The half mirror creates a complete mirror reflection on the outside of the lens while completely concealing the eye. On the other hand, the flash mirror coating is less dense and has a transparent mirror appearance. Consult your optometrist to determine which option is best for your vision needs.
In the colder months, it can be frustrating when your glasses consistently fog up every time you step. Fog makes it difficult to see, which can be hazardous, especially outdoors or driving. This is even more dangerous for police officers and people who respond to emergencies.
Even if you don't live in a cold climate, your lenses may fog up during sports activities or when you are hot and perspiring. At least one eyeglass lens coating company has created a permanent coating designed to eliminate moisture condensation on lenses that cause fogging.
Photochromic lenses, also called transitions, automatically darken when exposed to sunlight and become apparent when you go back indoors. These lenses are available in all materials and designs. You should consider them if you want to avoid purchasing another pair of prescription sunglasses or if you have light sensitivity.
Keep in mind that photochromic lenses darken and lighten to varying degrees. Some brands take longer to change than others. Discuss your needs and options with your eye doctor.
Lens tinting can improve eyesight or give your glasses a little extra flair. With sunglasses, a yellow tint may improve contrast, whereas a gray tint may not affect how colors are seen. Cosmetic tints are available in various hues, tones, and graduations. Computer Vision Syndrome, or CVS, has recently received much coverage. Did you know that a specific lens tint for your glasses helps lessen CVS-related eyestrain?
UV protective, scratch-resistant, and anti-reflective coatings and Mirror Lenses Coating can all help protect your vision and your lenses. Please speak to our optometrist to find out which coatings are most beneficial for you.
