Prescription eyewear refers to glasses or contact lenses that are specifically designed to correct vision problems. These items are made based on an individual's unique vision prescription, which is determined by an eye care professional, such as an optometrist or ophthalmologist. The prescription indicates the necessary lens power to help improve clarity and focus for the wearer. The lenses in prescription eyewear can address various vision issues, including nearsightedness, farsightedness, and astigmatism. In addition to correcting vision, prescription eyewear can also provide protection from harmful UV rays and reduce eye strain. Many styles and designs are available, allowing individuals to choose eyewear that suits their personal preferences and lifestyle.
