Eyewear refers to optical devices worn to correct vision or protect the eyes. Prescription glasses and contact lenses are common solutions for refractive errors like nearsightedness, farsightedness, and astigmatism. Fashion eyewear, including sunglasses and blue light-blocking glasses, serve both aesthetic and protective purposes. Advanced options include specialized lenses for computer use or sports activities. Regular eye exams are essential for determining the need for eyewear and monitoring eye health. Properly fitted eyewear enhances visual acuity and safeguards eye health in various environments.
