How to Buy Polycarbonate Sunglasses Lens

Lightweight polycarbonate sunglass lenses are impact and scratch resistant. Polycarbonate sunglasses filter nearly 100 percent of UV rays. Active children can benefit immensely from wearing polycarbonate sunglass lenses. The high-tech composition of durable, thin polycarbonate lenses provides comprehensive protection and comfort.

Instructions

Difficulty: Moderately Easy

1. Select the proper frame for polycarbonate lenses. Active eyeglass wearers should purchase sports-frame sunglasses along with polycarbonate lenses to safeguard eyes while playing sports. Don't rely on the impact-resistant lens alone for protection during sports and other strenuous activities.
2. Determine the general use for polycarbonate lenses. Sunglasses for children, fashion and sports have some similar requirements in that extra lens protection is wanted, but they have different aesthetic requirements.
3. Decide if the lenses will be photochromic if the sunglasses are for prescription wearers. Photochromic lenses darken with increased UV exposure. Polycarbonate's high impact and scratch resistance are an alternative to heavier traditional glass lenses.
4. Get colorful tinted lenses. Tinted lenses are most often selected for their fashion appeal. The lighter fashion tints are easily applied to polycarbonate lenses through absorption. However, tinting should be ordered when the lenses are manufactured as adding tint at a later date often has disappointing results.
5. Buy additional protective lens coating. In the long run, it's well worth the expense, as it precludes lens replacement due to scratching. Coated lenses are easier to clean and withstand dust and other airborne pollutants.
