An eye doctor, also known as an optometrist or ophthalmologist, is a healthcare professional who specializes in eye care. They perform eye exams, diagnose vision problems, and prescribe corrective lenses like glasses or contact lenses. Some eye doctors also provide treatment for eye diseases and conditions. In addition to vision correction, eye doctors can detect signs of serious health issues, such as diabetes or high blood pressure, through eye examinations. They may also perform surgeries, particularly ophthalmologists, who are medical doctors trained to treat complex eye conditions. Regular visits to an eye doctor are important for maintaining good eye health.
