Refractive error (RE) is the second-leading cause of preventable blindness and one of the most common causes of vision impairment worldwide. If the eye is unable to perfectly focus a light beam from an element onto the retinal surface, refractive error may result. In order to see clearly, the resulting image is blurry and needs to be corrected for refraction. Preschoolers’ eyesight is crucial since their sensory system is still growing and they run the risk of developing amblyopia or anisometropia. Refraction errors are also risk factors for a variety of eye disorders. Refraction errors that go uncorrected are a major cause of visual impairment and can lower productivity. Along with cataracts, trachoma, onchocerciasis, and childhood blindness, a refractive error has been identified as a vision problem whose detection and treatment would result in significant economic benefits and social development.
What is a refractive error?
Refractive error, also known as a refraction error, is a condition where light rays are not properly focused on the retina due to the eye’s shape.
Types of Refractive Errors:
- Myopia: A condition in which close objects appear clearly, but far ones don’t. Myopia reduces visual acuity in both school-age children and adults and makes up a significant portion of refractive error.
- Hypermetropia: Also known as hyperopia or far-sightedness, it is a vision condition in which nearby objects are blurry. Hyperopia is a common vision condition in adults.
- Astigmatism: When the cornea at the front of the eye has an uneven curvature, astigmatism frequently results. The cornea is typically smooth, evenly shaped in both directions, and equally permeable to light rays coming from both planes and directions. This anomaly could result in eyesight similar to peering into a warped, wavy mirror.
- Presbyopia: Age and presbyopia are related. After age 40, the eyes’ lens becomes less flexible and becomes stiffer. As a result, the eye loses its ability to focus, making close-proximity vision harder to read. It is almost as though hyperopia but in adults.
Symptoms:
- Blurry vision
- Double vision
- Hazy vision
- Halo in bright lights
- Difficulty concentrating while reading or watching the screen
- The crossing of eyes in children
- Squinting
- Headache
