What is a Refractive Error? A refractive error happens when the eye cannot clearly focus images from the outside world. This causes blurry vision, which can affect our ability to see far, near, or both. It occurs when the shape of the eye prevents light from focusing directly on the retina (the light-sensitive layer at the back of the eye). 🧬
Types of Refractive Errors
Myopia (Nearsightedness): You can see near objects clearly, but distant ones appear blurry. Common in school-age children and young adults. Hyperopia (Farsightedness): You can see distant objects more clearly than near ones. Can cause eye strain, especially when reading. Astigmatism: Caused by an irregular shape of the cornea or lens. Vision is distorted or blurred at all distances. Presbyopia: Age-related difficulty in focusing on near objects. Starts usually after age 40.
Prevention & Eye Care Tips While some refractive errors are hereditary and not fully preventable, you can protect and preserve your vision by: 👓 1.
