Prescription spectacles

Prescription spectacles are corrective eyewear designed to improve vision by compensating for refractive errors like nearsightedness, farsightedness, or astigmatism. They also address age-related vision changes, such as presbyopia, by using lenses tailored to the wearer’s specific prescription, often combined with protective features like UV-blocking tints for outdoor use.

These devices are typically sold over-the-counter or by prescription, depending on jurisdiction, and may be classified differently based on lens type or additional features. Regulation often focuses on safety standards for materials, optical accuracy, and compliance with vision correction guidelines, ensuring they meet performance and durability requirements for safe use.
