Trivex Lenses

Trivex lenses are made up of lightweight and impact-resistant material. As an alternative to polycarbonate lenses, Trivex lenses were developed in 2001 by PPG industries.

Trivex lenses are created by a urethane-based monomer and are constructed just as a regular plastic lens.

Advantages of Trivex lens

1. Lenses that are made from Trivex are resistant to scratches and breakage.
2. Trivex lenses are also resistant to chemicals like Acetone and other solvents. They are also resistant to alcohol and isopropyl alcohol.
3. Internal stress present in lenses can cause internal cracks but Trivex lenses are free of internal stress. Thus they do not cause internal cracks or cloudy vision.
4. Trivex lenses are lightweight. They have a lower density ratio than other plastic lenses making Trivex comfortable. This makes it suitable for old age people. With age the skin of the nose becomes sensitive and light eyewear is suitable to reduce irritation.
5. Trivex Lenses have Uv protection from UV-A and UV-B radiations.
6. The aspheric lens design reduces the extra magnification that is done in ordinary lenses thus you get natural wider vision without distortion.

Disadvantages of Trivex Lens

1. Trivex being a new product is difficult to find among retailers. They are available online which means you will not be able to test them physically.
2. Trivex prescription lenses are very expensive. After the simple lens other add ons increase the price even more. Progressive lenses increase the price even more.

Will Trivex lenses suit you?

Trivex lenses are exceptionally lightweight and have excellent impact resistance and other optical properties. These features make these lenses extremely comfortable to wear.

With all the features you get with Trivex Lenses, you have to give something too. Trivex lenses are the most expensive lenses.

Your eye doctor will recommend if you are suited for Trivex lenses.

Polycarbonate Lenses
