Step-by-step explanation:
Myopia, also known as nearsightedness, is a condition where distant objects appear blurry while nearby objects are clear. It can occur due to genetic factors or spending excessive time doing close visual work. Myopia typically starts in childhood and progresses until about age 20, but it can also develop in adults due to visual stress or health conditions like diabetes.
Common signs of myopia include difficulty seeing distant objects, such as a movie screen or a whiteboard in school. It can be corrected using corrective lenses like eyeglasses or contact lenses, or through refractive surgery performed with a laser.
