The Ultravex lens can withstand a 5/8-inch steel ball weighing approximately 0.56 ounces falling from a height of 50 inches (1.27 meters) onto the top horizontal surface of the lens.

Made from a unique lens material that has a network molecular structure, the Ultravex lens is durable enough to withstand bumps and scratches, providing protection at work and for sports.

HIGH RESISTANCE TO IMPACT

Ultravex’s high impact resistance capabilities come from its unique chemical monomer molecular structure. The impact resistance is seven times that of ordinary lenses.

ADJUSTMENT CONVENIENT

Like standard lenses, Ultravex lenses are easy and convenient to handle in the cutting process and in RX laboratory production. They are strong enough for rimless frames.

HIGH ABBE VALUE

Lightweight and strong, Ultravex lenses can reach an ABBE value of up to 43+, providing very clear and comfortable vision, and relieving fatigue and discomfort after a long period of use.
