TR-90 Frame: TR90 was produced through Swiss technology as a thermoplastic material that is incredibly durable, flexible, and lightweight. Glasses made with TR90 are extremely comfortable because they have a flexible quality. Since they are flexible, they can bend under pressure and contour your face comfortably. This flexibility also makes TR90 glasses resilient to damage. Because the material is pliable, they are far less likely to break or bend from impact. If you’re guilty of constantly dropping your glasses, fear not! TR90 frames can prevail!

Photochromic: These are clear eyeglass lenses that are clear (or nearly clear) indoors and darken automatically when exposed to sunlight. Other terms sometimes used for photochromic lenses include "light-adaptive lenses," "light intelligent" and "variable tint lenses."

How photochromic lenses work
The molecules responsible for causing photochromic lenses to darken are activated by the sun's ultraviolet radiation. Because UV rays penetrate clouds, photochromic lenses will darken on overcast days as well as sunny days.

What Does Polarization Mean?
Sunlight Scatters In All Directions. But When It Strikes Flat Surfaces, The Light That Is Reflected By The Surfaces Tends To Become Polarized — Meaning The Reflected Light Beams Travel In A More Uniform (Usually Horizontal) Direction. This Creates An Annoying And Sometimes Dangerous Intensity Of Light That Causes Glare And Reduces Visibility. Polarized Lenses Have A Special Filter That Blocks This Type Of Intense Reflected Light, Reducing Glare And Discomfort.

UV-400: 'UV400' Refers To Uv Rays At The Top End Of The UV Spectrum, Up To The 400-Nanometre Wavelength. Sunglasses With This Level Of Protection Block An Even Wider Spectrum Than The Ce And British Standard Models, Making Them The Ultimate Protection For Your Eyes.
