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.

Drooping Eyelids

A drooping eyelid can be caused by excess skin or a problem with the muscle which controls the eyelid. Birth defects, tumors, surgery, and some diseases can also cause the eyelids to droop. It can occur in one or both eyes and can be so severe as to impair vision.

Excess skin is common in older people as the skin loses its elasticity. Connective tissue diseases which cause the skin to lose its elasticity are collectively referred to as dermatochalasis. Blepharochalasis is excess eyelid skin caused by recurring swelling, and is common in young people.

Levators are the muscles which lift the eyelids. When drooping eyelids impair vision, eyelid surgery to tighten or bypass these muscles may be necessary.
