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.

Some people think that eyeglass wearing makes the wearer rely on them. In fact, eyeglass wearing causes no permanent visual change. Based on the misconception, those people are not willing to wear eyeglasses when they just feel good with the vision. But in sometimes, their actual vision is burry, thus bringing more risk when they are driving on the highway, especially at night.

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.

Along with their popularity, eyeglasses are still under restless innovations. This writing describes comprehensively about aspects of eyeglasses: frames materials, frame styles, lenses, sunglasses and so on.
