What are Refractive errors?

Refractive errors are highly prevalent worldwide, affecting billions of people. These vision problems result from the eye’s inability to properly focus incoming light.


Causes of Refractive errors

These conditions result from abnormalities in the shape of the eye, which affect the way light is focused on the retina.


Symptoms of Refractive errors

Difficulty in focusing light on the retina, resulting in blurred vision


Treatment of Refractive errors

Corrective lenses like glasses or contact lenses can effectively address these issues.

Refractive ErrorsCausesSymptomsTreatments

or Nearsightedness

Eye-Ball being too long or oval-shaped rather than round

Clear near vision and blurred distant vision, people generally squeeze their eyes to see the distant object

Often involves corrective lenses like glasses or contact lenses.

Refractive surgery such as LASIK can reduce the reliance on corrective lenses.


or Farsightedness

When the eyeball grows too short from front to back

Clear distance vision but discomfort with eye strain for near work.

Often involves corrective lenses like glasses or contact lenses.

Refractive surgery such as LASIK can reduce the reliance on corrective lenses.



Irregular shaped cornea

Blurred vision for distance and near. Generally have eyestrain and headache.

Commonly corrected with prescription eyeglasses or toric contact / Ienses that compensate for the irregular curvature of the cornea or lens.

Refractive surgery and IOLs may also be an option in some cases.



Lens begin to lost its elasticity/accommodating capacity.

Difficulty in focusing near object and clear distant vision. Symptoms begins at the age of forty.

Corrected by means of bifocal/progressive lenses for near and intermediate vision.
