JUST SCRATCHING THE SURFACE

There are a number of lens materials available to consumers that fit a variety of needs. While most provide wearers of eyeglasses all that they may be looking for, some require add-on coatings that make them even more perfect choices. For instance, “high-index” lenses are lightweight and allow those with strong prescriptions to wear thin lenses. To make them even better, users of high-index lenses often opt for an “anti-reflective” coating that improves clarity and reduces reflection, thereby improving vision under strong light and at night. Those choosing highly impact-resistant “polycarbonate” lenses often elect to protect this easily scratched material with a “scratch-resistant” coating. Ask about the various available coatings, including UV-blocking, when purchasing lenses. The lenses you select for your eyeglasses often will determine how happy you are with your eyewear. Of course, the frame you choose is important to both your appearance and your comfort, but the lenses you choose influence appearance, comfort, vision, and safety. Photochromic coated lenses adjust to the amount of ultraviolet light to which they are exposed, thereby reducing eyestrain and eye fatigue for the wearer.
