Astigmatism Symptoms #6: Squinting
Squinting refers to the action where one is looking at an object with partially closed eyes. It is most commonly seen among those who have refractive errors but are not wearing corrective glasses or contact lenses. The act of squinting helps to temporarily improve their vision by changing the shape of the eye to make it rounder, allowing more rays of light to meet at one point.
Squinting also lowers the amount of light that enters the eye allowing better focus. Patients with astigmatism often squint to decrease the amount of light entering the eyes and to slightly change the shape of their eyes. The use of pinhole glasses can have the same effect as squinting because the glasses limit the amount of light entering the cornea.
