Refractive errors are common vision problems that occur when the shape of the eye prevents light from focusing directly on the retina. This can lead to blurry vision, making it difficult to see clearly at various distances. The main types of refractive errors include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. These conditions can often be corrected with eyeglasses, contact lenses, or refractive surgery. Regular eye exams are important for detecting refractive errors early, allowing for timely treatment and improved vision. By addressing these issues, individuals can enhance their quality of life and enjoy clearer sight.
