Refractive errors are corrected with eyeglasses, contact lenses, or surgery. Eyeglasses are the easiest and safest method of correction. Contact lenses can provide a wider field of vision; however they are associated with a risk of infection. Refractive surgery permanently changes the shape of the cornea.
Then, what are the four common refractive errors?
The four most common refractive errors are: myopia (nearsightedness): difficulty in seeing distant objects clearly; hyperopia (farsightedness): difficulty in seeing close objects clearly; astigmatism: distorted vision resulting from an irregularly curved cornea, the clear covering of the eyeball.

Cactus plants can grow new plants from pieces cut from the main cacti.
