Product Features

The importance of a good semi-finished lens to RX production:

Glasses Semi Finished Lens Blanks 1.61 Index MR-8 Monomer UV400 Protection

High qualified rate in power accuracy, tability, cosmetics quality

High optical features

Good tinting effects and hard-coating/AR coating results

Realize the maximum production capacity

Punctual delivery

Free form laboratory requires accurate and stable base curve / radius / thickness of high quality semi-finished lenses. Substandard semi-finished lenses will result in a large waste of capacity, labor, click fees, delivery delays, etc., and the consequences will exceed the cost of semi-finished lenses.

1.61 ASP UV400 lens:

----Lighter weight and thinner thickness, up to 50% thinner and 35% lighter than other lenses.

----Higher resistance to scratches and impact.

----Fuller protection against UV rays.

----Easier to clean due to the water and dirt repellent surface.

----Aspherical design, offer the wearers amazing visual comfort and aesthetic appeal.

Coating Choice

AR Coating: A Perfect Companion for High-Index Lenses

Glasses Semi Finished Lens Blanks 1.61 Index MR-8 Monomer UV400 Protection

For the best vision and appearance, it's a good idea to have an anti-reflective lens coating (AR coating) applied to high-index lenses. AR-coated high-index lenses transmit up to 99.5 percent of light to the eye for optimum vision.

And because AR coating virtually eliminates lens reflections, it makes high-index lenses appear nearly invisible, so others see your eyes, not your lenses.

Also, studies have shown that eyeglass lenses with anti-reflective coatings provide sharper night vision with less glare — a real advantage for night drivers.
