They often provide a range of products from various brands and may offer additional services such as eye exams conducted by licensed optometrists. In addition to selling eyewear, optical stores typically assist customers in finding the right fit and style for their needs. Many stores also provide lens options, such as prescription lenses and blue light blocking lenses, to enhance vision and comfort for different activities, including reading and using digital devices.
