Today, computer is becoming important for both children and adults. Kids may spend hours in front of a computer every day, so that it is necessary for parents to consider what visual effects may be brought by computers.

People with presbyopia are supposed to buy reading glasses from eye doctors, rather than simply pick up one pair from drugstores. On one hand, those one-size-fit-all reading glasses are problematic for people with different prescriptions in two eyes, resulting in side effects such as headache. On the other hand, regular eye exams from eye doctors can detect underlying vision problems as early as possible.

Besides eyeglasses for regular wear, there are still various types of specialty eyewear or “task-specific” eyeglasses. Since one pair of eyeglasses does not fit all sizes in most cases, those specialty eyeglasses such as computer glasses, driving eyeglasses and protective glasses are helpful in specific circumstances.

Another reason for blurred vision and eyestrain at the computer is binocular dysfunction, in which condition a prism power may be added to your glasses.
