Answer:
There are 2 types of lenses prescribed for correcting or improving vision. These include:
Eyeglasses. Eyeglasses are the most common form of eyewear used to correct or improve many types of vision problems. They consist of a frame that holds 2 pieces of glass or plastic, which have been ground into lenses to correct refractive errors. Refractive errors can include trouble seeing far away (nearsightedness or myopia) and trouble seeing close up (farsightedness or hyperopia). They can also include blurring due to an irregularly shaped cornea (astigmatism). Eyeglasses work by adding or subtracting focusing power to the eye's cornea and lens.
Contact lenses. Contact lenses are worn directly on the cornea. Like eyeglasses, contact lenses correct refractive errors. They do this by adding or subtracting focusing power to the cornea and lens.
DIFFERENCE
The doctor may need to perform various tests to see how your vision is when wearing contacts. ... Because eyeglasses sit some distance away from your eyes, the prescription for glasses is typically a bit stronger than for contact lenses. This is the primary difference between the two prescriptions
