Refractive errors are vision problems that occur when the shape of the eye prevents light from focusing directly on the retina. The main types of refractive errors are myopia (nearsightedness), hyperopia (farsightedness), astigmatism (distorted vision), and presbyopia (age-related difficulty in seeing close objects). Symptoms include blurred vision, difficulty reading or seeing distant objects, and eyestrain. Treatment usually involves wearing glasses or contact lenses, though refractive surgery is an option for some individuals.
Refractive errors mean your eye doesn’t bend light the right way, making it hard to see clearly. It’s like when a camera is out of focus, and the picture doesn’t look right. Glasses, contacts, or sometimes surgery can help make everything look clear again.
