Eye exams are an important part of maintaining good overall eye health. Having regular eye exams is a critical component in detecting eye diseases or problems in their early stages when they are often still treatable. With regular eye exams the doctor can sometimes detect a problem before any noticeable symptoms begin to occur. Eye exams are necessary to prescribe proper corrective lenses or contacts, but can also serve a more specialized purpose, such as determining eligibility for laser refractive surgery, or monitoring an eye condition. Regular eye exams are the key to preserving good vision for life.
