Photochromic lenses

Have you ever wondered how Transitions® lenses work? The magical mash-up of sunglasses and eyeglasses, when you see them change color, you feel like – the future is now. Transitions® are an example of photochromic lenses.

Some other names for photochromic lenses are Light Adaptive, Variable Tint, Photochromatic, but many people call just them by the popular name brand Transitions®; you could say they’re the the “Kleenex” of photochromic lenses.

If we start with the etymology of the word, photochromic comes from two Greek words; photo meaning light and chroma meaning color.

Photochromic lenses change color when exposed to light.

You can get clear photochromic eyeglasses that change all the way to dark sunglasses, or photochromic sunglasses which are just for outdoor wear (and do not get completely clear.)

So how do Transitions® lenses work? When exposed to light, the photochromic molecules in the lenses begin to change structure, like in the illustration below. This new arrangement allows the molecules to absorb more light which causes the lenses to darken. Most photochromic lenses to UV light; that’s why they change when you’re in the sun yet remain clear indoors.

Temperature also has effect on the reaction time of the molecules in photochromic lenses. On a cold day, your lenses will react more slowly than on a warm day.

In this video, one of FramesDirect.com’s expert opticians, Travis, explains further:

 

Transitions® lenses continuously adapt to changing light conditions and block 100% percent of harmful UVA and UVB rays. Having your lenses give you the exact amount of protection you need to see clearly, means your eyes are doing less work. And there’s the added benefit of only having one pair of glasses for indoors and out!

Safety glasses: For Work, Hobbies, and with your Prescription

Safety glasses have come a long way. You used to have to buy big goggles to put over your prescription glasses, which were cumbersome and could get quite foggy – making your work even harder. Whether you need prescription lenses, or not, safety glasses are a lot less bulky these days.

Even with a streamlined look, safety glasses should (of course) protect your eyes from whatever hazards you may encounter.

The best way to ensure your safety glasses will give you reliable protection is to purchase frames and lenses that are ANSI rated.

ANSI stands for American National Standards Institute; they have minimum performance requirements for glasses and put frames and lenses through a series of tests – including a high velocity test conducted with a ¼ inch steel ball!

Whether you’re buying safety glasses (or prescription safety glasses) for work on a construction site, a laboratory, or for your kid to wear to play in a baseball game, the standards are the same. At FramesDirect.com we carry multiple brands of ANSI rated safety glasses and goggles, so you can find the the perfect pair for any activity. And if you buy prescription glasses in a safety frame, we will fit them with polycarbonate lenses that are ANSI rated. Polycarbonate is the most impact-resistant lens material. A full range of lens options are available including anti-fog and anti-scratch coatings and tinting.

You only get one pair of eyes per lifetime, so if you have a job that puts your eyes in harm’s way or just enjoy some of the more dangerous hobbies, its worthwhile to find a pair of glasses that fully protects them! All our operators at FramesDirect.com are trained opticians, so if you have any questions about getting the best safety glasses for your needs, just let us know.
