Fotocromatic Glasses

You need UV protection each and every time you step outside, but you can find other ways to protect your eyes from the glare and bright conditions that come with the great outdoors. Sunglasses might help prevent squinting, discomfort, and eye strain due to the sun—but not absolutely all sunglasses are created equal. Explore the differences between polarized and photochromic lenses, and the benefits and drawbacks of each. Photochromic lenses are eyeglasses lenses that can be clear indoors, and to automatically darken in outdoor, bright conditions. Effectively, they are normal eyeglasses that transition to sunglasses, to allow for improved visibility in the absence or presence of light. They are also known as light-adaptive lenses and variable tint lenses. In one sort of technology, molecules of silver chloride or another silver halide are embedded in photochromic lenses.

Consult your doctor about how you may use these photochromic lenses for blue light along with other solutions to protect your vision while undertaking your job responsibilities. For obvious reasons, photochromic lenses cost a lot more than regular eyeglass lenses. But customers get the freedom to not have to carry a couple of prescription sunglasses whenever it really is bright out. Many people opt for anti-reflective coating on their photochromic lenses to enhance their performance.

Many large optical companies around the globe have been actively pursuing development of plastic photochromic lenses for the past ten years. The statement that the electron cannot jump an extended distance from the silver speck to a doubly charged copper ion should be modified somewhat. Once the colloid is irradiated with visible light, there exists a small but finite probability that a single electron will acquire so much energy that it can make a lengthy jump. This infrequent broad jump by the electron gets the result that a photochromic glass fades somewhat faster when it’s irradiated by long wavelengths than it does in the dark. This slight acceleration of the fade rate by long wavelength irradiation is named optical bleaching. The fading that occurs even in the dark is called natural or thermal fading.

Eliminates condensation and moisture on the lens, ensuring optimal fog free visibility generally in most every condition. This drastically reduces the appearance of thin hairline scratches, keeping your lenses in perfect shape longer.
This also implies that since the UV rays that enter a car already are filtered by the windshield, photochromic eyeglasses won’t themselves darken. Photochromic lenses are clear indoors, but a chemical reaction within the lens causes them to darken after about 30 seconds of exposure to ultraviolet radiation from sunlight. After moving indoors, the lenses become clear again within minutes.
