INSURANCE FOR YOUR EYES
Sunglasses protect your eyes from harmful ultraviolet (UV) rays, reduce eye strain, and protect you from flying debris and other unexpected hazards.
The American Academy of Ophthalmology advocates wearing sunglasses anytime you’re outdoors, but particularly when:
It’s summer (when UV radiation is at least 3 times higher than it is during winter).
You’re at the beach or near water.
You’re outside at high elevations.
You’re participating in active sports.
In addition, if you have an eye disease, have had cataract surgery, or are taking photosensitizing drugs, you should wear sunglasses whenever you go outside.
What is Polycarbonate?
Polycarbonate is a versatile, tough plastic used for a variety of applications, from bulletproof windows to compact discs. The main advantage of this material over other types of plastic is its great strength combined with light weight. While acrylic is 17% stronger than glass, Polycarbonate is nearly unbreakable. Add to this the advantage that it is just 1/3 the weight of acrylic, or 1/6 as heavy as glass.
Polycarbonate is used to make eyeglass and sunglass lenses because of its excellent transparency, durability, and high refractive index. This means that it bends light to a far greater degree than glass or other plastics of equal thickness. Since prescription lenses bend light to correct vision, Polycarbonate lenses can be thinner than glass or conventional plastic, making it the ideal material for heavy prescriptions. This extremely thin lens is virtually indestructible, an important safety factor for both youth and active adults.
What does Polarized mean?
Polarized Lenses are a great feature if you enjoy water sports or are especially sensitive to glare. When light reflects off of flat surfaces, such as a lake, the light waves align in horizontal patterns, creating intense glare. The filters in polarized lenses block these horizontal light waves, substantially reducing blinding glare and its resulting eyestrain.
