Refractive errors result from the eye’s inability to focus images clearly on the retina, which results in vision problems. In a normal eye, the cornea and lens concentrate the incoming light rays onto the retina, producing a clear image that is sent to the brain. More so in younger people, the lens is elastic. The ciliary muscles change the curvature of the lens during accommodation to focus images correctly.

Unclear vision for objects at distant, close, or both objects is the most common sign of refractive errors. Refractive error can contribute to eyestrain, where prolonged looking can cause ocular surface desiccation, which can irritate the eyes and cause itching, redness, weariness, and a feeling of a foreign body. Children who have refractive error have signs such as frowning, squinting, or frequent blinking or rubbing of the eyes when reading.

Refractive errors in South Delhi can be treated with the help of eyeglasses, contact lenses or refractive surgery, depending on the severity of the disease. People above 60 years of age are most required to undergo refractive surgery. The four most common types of refractive errors are myopia, astigmatism, presbyopia and hyperopia. Each one shows kind of similar symptoms, although some can vary and have specific symptoms, such as myopia, where a person is not able to see objects placed at a distance, whereas, in hyperopia, a person is not able to see objects placed near them.

Types of refractive errors are detailed as:

1. Myopia: Myopia is also called nearsightedness, is likely to be discovered at an early age. This eye disease can mostly be seen in a younger age population. It can be cured with surgical treatment if not able to recover with other methods.

2. Hyperopia: Hyperopia is also called farsightedness. Children or teenagers who develop hyperopia at an earlier age it is likely to have it lessen as they grow into adulthood. But if the case is mild or advanced, the vision could get blurred and might require treatment.

3. Astigmatism: In this case, the cornea has asymmetrical curvature, due to which the light rays entering do not spread equally. This can cause blurriness at different levels depending on the curve of the cornea.

4. Presbyopia: This type of refractive error occurs mostly in people who are above 40 years of age. After a certain age, the lens gets rigid, and it becomes difficult for it to flex around which is why it becomes hard for it to focus.

With refractive surgery, it is possible to recover your vision, and it also improves the state of your eye. After the surgery, you would not have to wear eyeglasses or contact lenses ever again. You should first visit an eye specialist who will guide you through the treatment.
