Pinhole effect

Strabismus
Squinting acts like a pinhole, forcing light through a small region of the eye. This lets only the straightest rays of light enter the eye; they do not get bent off alignment by irregular curves (astigmatism) or length (nearsighted or farsighted) of the eye. Squinting does not appreciably change the cornea's shape; the force of the eyelids is evenly distributed over the eye, especially the sclera.

How can you break the habit of squinting my eyes?

Spectacle/sunglasses

Squinting
Generally, the squinting of one's eye is not a habit. It is mostly for one of two reasons: The need for a refractive correction (glasses or contacts) or light sensitivity in sunlight or bright lights. If when you squint you can see better, you should see an eye doctor for refractive correction. If you see just as well with/without squinting obtain sunglasses, polarized with 100% UVA & UVB blocker

Why is my 3 year old son squinting his eyes?

Vision issues

Squinting
Squinting eyes can be a tic or a sign of eye irritation. However, often it's a sign of visual problems or a need for glasses. Squinting changes the shape of the eyeball and can temporarily improve visual acuity. Teachers can often spot a child with vision issues squinting at the blackboard. If it's lasting more than a few days, see an eye doctor.
