Strabismus is more common in children than adults, and its cause isn’t always straightforward.

Sometimes, it can be associated with cerebral palsy, Down syndrome, or premature birth.

Many times, nearsightedness is discovered in children between 8 and 12 years old.

How to Treat Squinting Eyes

The treatment for eye squinting will depend on the cause.

Ophthalmologists also can correct farsightedness and nearsightedness with refractive surgery.

This is especially important if you have other vision-related symptoms, such as headaches or eye strain.

They can evaluate for causes of these vision issues, including strabismus.

It’s possible that vision problems from strabismus can cause trouble in school.

Squinting in these situations may indicate farsightedness, nearsightedness, or another vision problem.

An eye exam can help pinpoint why you’re squinting.

Common treatments include eyeglasses and contact lenses.

Surgery also can correct strabismus, farsightedness, or nearsightedness when needed.
