Squinting

Persistent squinting can make you feel tired and eventually cause wrinkles. For some it becomes a matter of habit, but it can be an early sign of vision problems or an eye condition.

If your vision is less than adequate you may have begun squinting without really noticing that your vision has declined. You may not even notice that you are squinting until someone point it out to you. Nearsightedness and farsightedness are common refractive errors that may cause you to squint. More often the inability to adjust between near and far vision is the problem. Vergence disorders affect your eyes' ability to turn outward or inward and work together properly.

Light sensitivity also causes squinting and can be a sign of more serious underlying problems including cataracts, corneal abrasions, retinal detachment, and central nervous system disorders.
