NEVER HIDE PHOTOCHROMIC LENS
What Are Photochromic Lenses Used For?
Photochromic lenses are ideal for people who need to wear glasses all of the time, these lenses look like regular clear lenses when indoors but automatically darken when moving into a brighter area. Ultraviolet (UV) rays from the sun affect the molecules in the photochromic lenses so they change colour. They will darken in the light even on overcast days as UV rays still penetrate clouds.
This provides you with the best possible vision in all lighting through different shades of tint, without you even needing to think about it. As Transition is the most well-known brand of photochromic lenses, these types of glasses are often referred to as ‘transition lenses’. They’re also sometimes called adaptive lenses, auto-tinted lenses or variable-tint lenses. Photochromic glasses are not to be confused with polarised glasses (sunglasses). These have a set tint that protects from glare but they aren’t changeable; they don’t adapt to light in the same way photochromic lenses do.
How do Photochromic lens work?
Photochromic lenses have existed in one form or another since the 1960s. The technology has changed a lot since then, but the fundamental principles remain the same.
In general, these lenses work by using chemical reactions that are triggered by UV exposure. The result of the chemical reaction is a color change in the lens.
The very first photochromic lenses were made of glass and coated with silver chloride and silver halide, among other molecules. These silver compounds underwent a chemical change when they interacted with waves of UV light. The chemical change caused them to darken. The reaction reversed when the UV light was gone.
Today, the lenses are made from several different materials. Proprietary photochromic dyes are added to these materials in a variety of ways. The molecules within these dyes undergo color changes at different rates when exposed to UV light.
The lenses should darken in proportion to the amount of UV light they receive. This means that the brighter it is in your environment, the darker your lenses become.
