The TR90 sunglasses line by LALIZAS has been created to satisfy the most demanding needs of yours. The TR 90 material used in the frames of the sunglasses makes them safer against the extreme temperatures and more durable to continuous and harsh use. Additionally, the lenses used are polarized and thus the glare and eyes strain are reduced substantially. The modern design, as well as, the specialized manufacturing, makes the sunglasses ideal for use in sports, but also in other activities which involve prolonged sun exposure. 

TR90

The TR 90 material is a transparent polyamide with good heat resistance and excellent fatigue behaviour. It is lightweight, resistant to stress cracking and stands up well against UV exposure. That is why it is commonly used for the creation of sport and other impact-resistant eyewear frames. Additionally, due to the fact that it contains no plasticizer and resists cosmetic chemicals and perspiration, it offers a very good alternating bending strength and it can enhance the design and performance of sport and safety spectacle frames. It also exhibits low moisture absorption and dimensional stability, while its outstanding weathering stability, makes it particularly suitable for eyewear frames.

UV Protection

The most important benefit that sunglasses should provide is protection from ultraviolet radiation (UV), which contributes to various eye diseases. Ultraviolet radiation has been linked to cataracts, benign growths on the eyes surface, cancer of the eyelid and of skin around the eyes and photokeratitis (snow blindness), a temporary but painful sunburn of the eye’s surface. UV protection is the most important feature to take into consideration while looking for sunglasses. The FDA, the government agency that oversees sunglass manufacture and sales in the U.S., recommends that customers should look for sunglasses with lenses that block 99-100% of UVA and UVB radiation (100% is best) and therefore provide UV 400 or 100% UV protection. 

“POLARIZED”

Lens The bright sunlight is reflected on many surfaces that surround us, such as water, snow, pavement, dust, buildings, ice, sand, wet road surfaces and windshields and resulting to an annoying glare for the eyes that reduce contrast and visual sharpness. The eyes cannot eliminate reflective glare independently. In order for the eyes to focus, they allow the access of even the slightest light and in this way various types of light “penetrate” the eyes, including the bright sunlight. The result is tired eyes, headaches, poor vision and sun damage to the eyes. Even if the eyes can’t “apprehend” the UV rays, they should be of concern, because of their long term damaging effects on the eyes. Polarized lenses are designed to substantially reduce or even eliminate reflective glare by selectively absorbing the light waves travelling in all directions except the vertical plane. At the same time UV rays are blocked. Bear in mind that the only thing that regular lens without polarizing film does, is just to darken the eyesight without protecting the eyes. In other words, polarized lenses are ideal for anybody who wants to avoid glare and to improve their vision in the sunlight.
