What Are The Various Types of Lens Coatings?
After choosing the frames and lenses you want for your eyeglasses, it best to decide whether the coating for your lens is perfect for you. The right coating can enhance the performance of your eyes and lens. Here are some lens coatings that you should consider when buying new eyeglasses.
The anti-reflective coating is also called anti-glare or AR coating. It eradicates reflections from the back and front surfaces of your lenses. It also reduces halos around lights, creating a better cosmetic appearance, making your lenses almost invisible. Additionally, the anti-glare coating is excellent for night driving because it improves light transmission.
You probably know that too much exposure to UV radiation can cause severe damage to your eyes. UV radiation is also linked to macular degeneration and cataracts that are prevalent in older people. Lenses that can block UVA and UVB help prevent the devastating effects of UV radiation. Most sunglasses have built-in UV protection; however, the CR-39 plastic lens requires an added coating to guarantee maximum UV protection.
It is quite common for your glasses to fog up if you live in a cold climate. If you live in a warm environment, your lenses might fog up when you are hot and sweating or participating in sports. An anti-fog coating is available to permanently eradicate the condensation of moisture on your lenses that result in fogging.
Tinting your lenses can add some sense of style to your eyeglasses. Usually, a yellow tint increases contrast, while a gray one does not change color perception. Tints come in various shades, colors, and gradations to suit your needs. A special tint for your eyeglasses can help lessen eyestrain associated with Computer Vision Syndrome (CVS).
Photochromic lenses are also known as Transitions. They darken automatically to respond to sunlight and clear up when you are indoors. Almost all lens materials contain photochromic treatment, and they are great for people who are sensitive to light or those that cannot afford prescription sunglasses.
Mirror coating is perfect for you if you want a cosmetic lens that lets your eyes be hidden from view. Such coatings come in various colors, including blue, gold, and silver.
Your choice of a lens coating will depend upon your individual needs and preferences. Talk to your eye professional for advice about which ones are right for you.
