Glasses with shield-shaped frames provide a contoured fit for daily wear. The wide upper frame and lenses in this style of glasses tapers around the eyes to protect against exposure to impact, ultraviolet rays and other hazards. Shield prescription glasses are available in strengths up to high RX and may be designed to meet safety standards.
Frames shaped like a shield allow for superior UV light protection. These glasses have a thick top rim and considerable lateral coverage with a wide lens shape. Some styles also feature side shields for additional protection. Any pair of shield glasses can be customized with prescription clear or tinted lenses.
