Ophthalmologists are medical doctors who specialize in eye care and vision health. They diagnose and treat various eye conditions, perform eye surgeries, and prescribe glasses or contact lenses. With extensive training, they can handle complex issues like cataracts, glaucoma, and retinal diseases, ensuring that patients maintain good eyesight throughout their lives. In addition to treating eye problems, ophthalmologists also play a crucial role in overall health. They often detect signs of systemic diseases, such as diabetes and hypertension, during eye examinations. Regular visits to an ophthalmologist can help catch these issues early, promoting better health and well-being.
