Do I need bifocals? 

Regardless of your age, if your eyes have trouble with alternating from farsightedness and nearsightedness, you may need bifocal lenses. The problem is a curvature of the eye's lens that changes how light is filtered and makes it difficult to focus when switching back and forth from short to long distance. 

Heredity and eye or visual stress may be the most common causes of nearsightedness. Environmental factors and work conditions also may contribute over time. Frequent computer use can worsen the condition. Farsightedness may be related to heredity. 

An eye doctor can perform an optometric exam to determine if you have nearsightedness and farsightedness and if you could benefit from wearing bifocal lenses.
