The American Optometric Association recommends a yearly eye exam for adults -- not only to detect and to diagnose vision changes or problems -- but also to maintain eye health. For example, glaucoma, a optic nerve disease often caused by increased pressure in the eye, commonly goes unnoticed by adults. Regular vision examinations are also important for the prevention of vision problems created or aggravated by today's academic and professional demands.
Twenty-first century lifestyles demand more from our vision than ever before. Adults in our technological society constantly use their near vision at work and at home. Environmental stresses on the visual system (including excessive computer use or close work) can sometimes induce headaches and/or visual difficulties which can be effectively treated with corrective lenses and/or vision therapy.
