There are many frame options available at each online eyeglasses store. Look for a vendor that has designer frames for men, women and kids.While frames give you the look, lenses let you see. Look for an eyeglasses store that offers the best variety of lens materials, like high-index plastic, polycarbonate or photochromic. Photochromic lenses automatically adjust their tint depending on the amount of sunlight present. Check to see if the online store offers common lens types such as single-vision lenses, progressives, bifocals and trifocals. Many lens add-ons like anti-glare and UV coatings, are available to help you see even better and can be included for an additional fee.
