What Eye Problems Look Like




 
 

5.Nearsightedness: What Happens
The cause is usually an eyeball that is too long. Or it can result from an oddly-shaped cornea or lens. Light rays focus just in front of the retina, instead of directly on it. This sensitive membrane lines the back of the eye (seen in yellow) and sends signals to the brain through the optic nerve. Nearsightedness often develops in school-age children and teens, so they may need to change glasses or contacts frequently as they grow. Multifocal contact lens or glasses and eye drops such as atropine can help slow the progression. The prevalence of myopia has been rising at an alarming rate, much of it being attributed to increased use of handheld devices and computers.

 

6.Farsightedness: What Happens
This problem results from an eyeball that is too short or an oddly-shaped lens or cornea. Light rays focus behind your retina and close objects look blurry. Your distance vision might be fuzzy, too. Severely farsighted children often have crossed eyes (strabismus) or lazy eye (amblyopia) and may have trouble reading. That’s one reason eye doctors recommend vision exams for young children.
