The corrected diagram of the defect of vision given in question is given above.
Nearsightedness (myopia) is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry. It occurs when the shape of your eye causes light rays to bend (refract) incorrectly, focusing images in front of your retina instead of on your retina.For adults, myopia can be reversed with refractive surgery, also called laser eye surgery. A laser is used to reshape the corneal eye tissue and correct the refractive error. Laser eye surgery is not recommended for children. In fact, the FDA has not approved laser surgery for anyone under the age of 18.
High myopia usually stops getting worse between the ages of 20 and 30. It can be corrected with eyeglasses or contact lenses, and in some cases, refractive surgery, depending on severity.Simple myopia: Myopia in an otherwise normal eye, typically less than 4.00 to 6.00 diopters. This is the most common form of myopia.The younger they are when they start becoming short-sighted, generally the faster their vision deteriorates and the more severe it is in adulthood. Short-sightedness usually stops getting worse at around the age of 20. There's currently no single treatment available that appears to stop this progression.
For permanent correction of myopia, you will want to consider refractive surgery, which changes the eye permanently and usually requires no daily correction afterward.
