Glasses refer to optical devices consisting of a frame that holds lenses, designed to correct vision or protect the eyes. They are commonly used to address refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia (age-related vision changes). In addition to prescription eyewear, the term also encompasses sunglasses, which are designed to shield the eyes from harmful ultraviolet (UV) rays and reduce glare. Glasses can serve both functional and aesthetic purposes, with a wide variety of styles, materials, and designs available to suit individual preferences. Show Less
