What are the most common eye diseases?
The most common eye diseases worldwide are:
Refractive errors like astigmatism, farsightedness (hyperopia), nearsightedness (myopia), and age-related loss of up-close focusing (presbyopia).
Age-related macular degeneration.
Eye injuries are also a leading cause of vision loss and blindness. Experts track and research them like diseases to find better ways to prevent and treat eye injuries.
Eye cancers and tumors, while rare, do sometimes happen, but often they’re detectable with regular eye exams. Fortunately, many eye tumors are benign (noncancerous). These benign growths may still need removal to prevent them from affecting nearby tissues, but aren’t a greater threat.
