Refractive Errors

Refractive errors are common vision problems that occur when the shape of the eye prevents light from focusing directly on the retina. This can result in blurred or distorted vision. The main types of refractive errors include myopia (nearsightedness), hyperopia (farsightedness), astigmatism (irregular curvature of the cornea), and presbyopia (age-related difficulty in focusing on close objects). These conditions can usually be corrected with prescription eyeglasses, contact lenses, or refractive surgery. Understanding refractive errors is essential for maintaining good eye health and ensuring clear vision.
