| 1)Choosing the Right Lenses There are many types of lenses and coatings - single vision, bi-focal, progressive, and computer lenses. We will explain the best options to match your current prescription and your daily needs. Hoya Sensity (Photochromic) Lenses Hoya Sensity Lenses are popular trend in California. They darken under sunlight and turn clear indoors for all-day comfort. For extra protection, Sensity Dark lenses even darken behind car windshields, making them ideal for driving. Both options help block up to 34 % blue light from computer monitors - protecting your eyes indoors and outdoors.  2)Understanding Lens Index The index number represents the thickness of a lens - the higher the index, the thinner the lens. The maximum index available is 1.74, which is nearly 50% thinner than standard plastic lenses. Recently, aspheric lenses have become more popular in higher index materials. In addition to being thinner, they also provide clearer vision with less distortion.
