The eyewear market is currently inundated with options. From unique shapes and styles of frames to vibrant tints, the variations are nearly unlimited. However, within the sea of choices, one type of eyeglass stands out! What are they, you ask! None other than photochromic lenses and glasses. They are stylish, multi-functional, and very practical. Whether it is summer, winter, or anything in between, photochromic glasses are something worth investing in.
What are Photochromic Lenses?
In simple words, we can understand photochromic glasses as eyewear that remains transparent indoors and darkens when exposed to ultraviolet rays from the sun. Thus, they double up glasses and sunglasses in a single frame. It is noteworthy to remember that photochromic lenses are not a novel phenomenon. They have a long history that dates back to the mid-1900s. For instance, the first photochromic lenses were patented in the 1960s and were made of glass. Thereafter, plastic versions were introduced in the 1980s and 1990s and gained mainstream traction.
In addition, it is noteworthy to remember that photochromic lenses and transition glasses mean the same thing. Simply put, Transitions® lenses are a branded type of photochromic lenses. But, they are often considered synonymous with the more general product. In addition, it is also quite common for people to omit the ‘s’ from the end of ‘Transitions’ and call photochromic lenses ‘transition lenses.’
The Working of Photochromic Lenses
The way photochromic lenses work is quite fascinating. Unlike regular sunglasses that block out a specific amount of UV rays with the help of polarisation, photochromic lenses are carbon-based. The molecules present in these lenses react to the UV rays of the sun, resulting in a change in the structure of the lenses, as they absorb light and take on a darker appearance.
The darkness of the photochromic lens is premised on the amount of light present: the brighter the light outside, the darker the lens becomes. Typical photochromic lenses take around 30 seconds to darken and they go back to normal in 2 to 5 minutes of stepping into an indoor space.
Currently, photochromic lenses are incredibly popular as they come with several advantages. What are they? Let us find out!
