What you need to know about polycarbonate lenses
Polycarbonate lenses offer a strong mix of safety, comfort, and durability — making them one of the most popular lens materials for both kids and active adults.
What are polycarbonate lenses?
Polycarbonate lenses are a type of high-index lens — meaning they bend light more efficiently, allowing the lens to be made thinner. They are best known for their outstanding impact resistance, which is why they have been a trusted lens material since the 1970s. They also come with a built-in anti-scratch coating. If you or your children tend to bump, scratch, or drop your eyeglasses, polycarbonate is worth a close look. These lenses are up to 10 times more impact resistant than standard plastic lenses, making them a top pick for active people of all ages.
Superb eye safety
Polycarbonate lenses provide an extra degree of safety for anyone who plays sports or stays physically active. In fact, most protective eyewear — such as sports goggles and safety glasses — is made from polycarbonate, even when no vision prescription (a lens power to correct your eyesight) is needed. These lenses also have built-in UV protection, which blocks the sun's ultraviolet rays. That makes them a smart choice for time spent outdoors, whether you're playing a sport, working outside, or simply enjoying the day.
Lightweight and thin
Polycarbonate lenses have a refractive index (a measure of how much the lens bends light) of 1.59. This means they can be made 20% to 25% thinner than common plastic lenses. They also weigh about 30% less than regular lenses. Less weight on the bridge of your nose means more comfort throughout the day — especially for people who wear glasses for long hours at work, school, or play.
Trivex lenses: a close alternative
Trivex lenses, developed in 2001, are made from a newer plastic material that shares many of the same strengths as polycarbonate. Like polycarbonate, Trivex lenses are thin, lightweight, scratch-resistant, and highly impact-resistant. However, Trivex lenses may be slightly thicker than polycarbonate lenses. For certain vision prescriptions, Trivex may offer sharper visual clarity and a bit more scratch resistance. Your eye care provider at Golden Triangle Eye Center can help you decide which material is the best fit for your prescription and daily needs.
