Eye Disorders Flashcards

Amblyopia

• Known as "lazy eye," characterized by dim vision, primarily affecting one eye.
• Often develops during childhood and can lead to permanent vision impairment if not treated.

Hyperopia

• Commonly referred to as farsightedness, where distant objects appear clear while close objects are blurred.
• Results from the eye being too short or the cornea being too flat, affecting light focusing.

Presbyopia

• A vision condition associated with aging, causing difficulty in seeing objects up close.
• Typically starts around the age of 40, due to the lens of the eye losing elasticity.

Nyctalopia

• Also known as night blindness, a condition that hinders vision in low-light conditions.
• Can be caused by a variety of factors, including vitamin A deficiency and certain eye conditions.

Diplopia

• Refers to double vision, where a single object appears as two.
• May result from various issues, including eye muscle imbalances or neurological conditions.

Astigmatism

• A refractive error caused by an uneven curvature of the cornea or lens, leading to distorted or blurred vision.
• Frequently described as "football-shaped" eyes and can affect both distance and near vision.
