Types of refractive errors in your eyes and how to correct them!

If you have ever operated a microscope or a telescope, you might have noticed that with even a slight change in focus, how blurry the subject can get. The human eyes work on a similar principle; light enters your eyes > it gets refracted / bent > and finally the Retina receives the light, enabling you to see. And a slight change in the refraction through your eyes could lead to eyesight problems.

About refractive errors

Certain abnormalities with the shape of your eyes could lead to refractive errors causing blurry vision, hazy vision, double vision, headaches, eye strain, or other issues. Refractive errors may develop over-time in adults or children, and some people are even born with it. Mild Refractive errors could hardly bother you; however, severe errors could require a vision correction. You may have refractive error on both of your eyes, on a single eye, or have different errors on both eyes.

Whatever be the issue with your eyesight, do remember that vision correction is highly accessible and simple. Also, do not feel left out because refractive errors are very common; approximately more than 2.3 billion people suffer from it.

Different types of refractive errors:

Refractive errors are broadly divided into 4 categories. Below, we take a look at each of them and try to understand them briefly.

Myopia / Nearsightedness

This condition affects your ability to see distant objects. Although the near objects can be seen clear and sharp, distant objects appear blurry.

Hyperopia / Farsightedness

People with this condition can clearly see faraway objects; however, they face difficulty seeing near objects. If the condition is significant, it can affect overall vision.


This condition affects both near and far eyesight. When light enters Astigmatic eyes, it focuses on multiple points instead of focusing on the Retina. This usually happens because of the mismatch in the curvature of the Cornea (surface of the eye) or the lens (inside the eye). If the curve is shaped like an egg or irregularly shaped instead of being shaped like a sphere, it will cause blurry vision at all distances.


This is a form of Farsightedness which is age-related. After 40-45 years of age, people usually begin facing this refractive error. With age, the lens in the eyes starts getting harder and less flexible, making it difficult to focus, especially on nearby objects. This issue is more than common among aging folks and could affect people in addition to other eyesight problems.

Treatments to correct refractive errors in eyes

A consultation with eye-specialists will not only help you with quick diagnosis but also treatment. Some of the common treatments for refractive errors are:


The most common treatment people opt for is glasses. Based on the type of refractive error and the severity, your doctor will prescribe lenses for best visual clarity.

Contact Lenses

Contact lenses work exactly as eyeglasses, minus the hassle of carrying the glass frame around. These lenses sit on your eyes’ surfaces to help with refractive error correction. Some people find it easy to wear and carry contact lenses because eyeglasses can limit certain physical activities.

Refractive Procedures

To correct the refractive errors in your eyes, you can opt for Laser-based eye surgery. Some of these surgeries are LASIK, SMILE, Contoura Vision, etc. are fast and precise. These procedures are fast and precise, and once the procedure is done, you will be able to see perfectly in no time and bid goodbye to your eyeglasses or contact lenses.
