Jan 12, 2023.

Photochromic lenses are one of your options when selecting eyeglasses. They’re the type of lens that transitions to a darker color when exposed to the sun or other sources of UV light.  Other names for photochromic lenses include:  Transition lenses Light adaptive lenses Variable tint lenses  What Are Photochromic Lenses Used For? Photochromic lenses are ideal for people who need to wear glasses all of the time. The two main purposes of photochromic lenses are to protect your eyes from UV light and to eliminate the need for a separate pair of prescription sunglasses.  The lenses provide complete protection from UVA and UVB rays at all times. This protective feature doesn’t depend on whether the lenses are clear or dark at any given moment.  UVA and UVB rays are the two types of UV light that can get through Earth’s atmosphere. They’re the main types that should concern you when it comes to your health.  How Can UV Light Damage Your Eyes? You’re repeatedly exposed to UV light throughout your lifetime, mainly in the form of sunlight. Over the course of your life, UV light can damage your eyes and the skin that surrounds them. This means that it’s important to protect your eyes by using products like photochromic lenses.  The types of eye damage that repeated UV exposure can lead to include:  Cataracts. The lenses in your eyes become cloudy and increasingly more opaque with this condition. Cataracts eventually lead to blindness. You need surgery to treat this condition.  Macular degeneration. This is a major cause of blindness in people who are older than 55. It’s the result of accumulated eye damage throughout your lifetime. There currently isn’t a cure.  Corneal damage. Your cornea is crucial for proper vision. UV lightwaves can particularly damage this part of your eye.  Skin damage. The skin surrounding your eye is vulnerable to UV damage as well. Examples of skin problems caused by UV include dryness, wrinkles, a loss of elasticity, and mottled pigmentation.   Certain cancers. UV light interferes with the base pairs that make up your DNA. This leads to mutations that could cause cancer. Squamous cell carcinomas are an example of a type of cancer that can invade your eye. Eventually, this type of cancer can lead to the surgical removal of your entire eye.
