Buying glasses online can be a convenient and cost-effective option, with many retailers offering discounts and promotions. According to CNET, some stores like Zenni Optical and EyeBuyDirect offer cheap prescription glasses for as low as $7, although prices may vary depending on the type of frame and lens quality. Online eyewear retailers often accept vision insurance, flexible spending accounts, and health savings accounts, making it easier to get the coverage you need.

Some online shops also offer premium lenses with anti-glare coating or photochromic lenses for added protection and convenience. However, be sure to read the fine print on return policies in case of any issues.
