Vision problems encompass a variety of issues that affect the clarity and comfort of sight. Common problems include refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia, which typically require corrective lenses or surgical procedures. More serious vision issues can result from diseases like glaucoma, macular degeneration, diabetic retinopathy, and cataracts, all of which can lead to significant or permanent vision loss if left untreated.

Symptoms of vision problems may include blurred or double vision, eye strain, headaches, night vision difficulties, or halos around lights. These issues can stem from factors such as aging, genetics, injury, infections, or chronic illnesses like diabetes. Regular eye exams are essential for early diagnosis and timely treatment. Depending on the underlying cause, vision problems can be managed through glasses, contact lenses, medications, or surgery, helping to preserve eye health and improve quality of life.
