What Are Transition Sunglass Lenses?

You may have already heard about transition lenses for glasses and sunglasses, but may not really understand what it is that they do for your eyes. This technology is advanced for sure, and has given people who wear prescription glasses a whole new way to be able to sport sunglasses without having to carry around two pair of eyewear. How these work is pretty simple; when a person is indoors, the lenses lighten and look like regular prescription sunglasses. However, when a person steps outside, they darken to shield their eyes from the sun, just like regular sunglasses.

So how does this all work? Another name for these lenses is photochromatic lenses. Many excellent pairs of eyewear bring all the protection from the sun with them to users, who are able to enjoy UVA/UVB blocking protection when their lenses darken in the sunlight. There are small particles within the lenses that, once they come in contact with ultraviolet light, begin to undergo a chemical reaction. It is this reaction that causes the lenses to darken. Once the sunglasses are no longer exposed to this ultraviolet light, they immediately return to being without shade and again appear as though they are regular everyday lenses.

Using some of these frames with some transition lenses in them will give you even more freedom to head outdoors and enjoy life for a while. Just knowing your shades are made with good quality materials means that you will be able to enjoy your activities more, so you may want to give them a try. The lenses themselves can be made to fit prescriptions in many thicknesses to accommodate individuals with varying degrees of vision. This can sometimes help them with sensitivity issues that many people who wear prescription lenses face.

If you take the fact that big name designers are now mass producing some of their sunglass style creations to satisfy the growing demand for style and fashion, you will also find a huge amount of websites that offer these shades to consumers. How can you tell which stores are trustworthy? You want to make sure that the company has been around for a while, and that they have received some positive consumer testimonials to prove it. They should always offer guarantees and even warranties for their customers to ensure their satisfaction. In addition, make sure that you are shopping with a company for transition lenses that offers reasonable shipping and handling service at a reasonable fee.
