Study Notes
Vision Problems
- Vision is the most dominant sense, critical for learning, movement, reading, and participation in daily activities.
- Vision impairment affects the visual system and can stem from various eye conditions.
- Nearly everyone will experience at least one eye condition requiring care over their lifetime.
Types of Vision Problems
- Astigmatism: Caused by an unevenly curved cornea, resulting in blurred vision for both near and far objects.
- Nearsightedness (Myopia): Light focuses in front of the retina due to an overly curved cornea or an elongated eye, making distant objects appear blurry.
- Farsightedness (Hyperopia): Occurs with an under-curved cornea or a shorter eye, causing nearby objects to be blurry as light doesn’t focus correctly at the retina.
- Xerophthalmia: A condition arising from vitamin A deficiency, leading to dry eyes potentially progressing to night blindness, corneal damage, or blindness.
- Strabismus: Characterized by misalignment of the eyes (often called lazy eye or cross-eye), commonly found in children but can affect adults.
Hearing Problems
- Impacted Cerumen: Build-up of earwax that obstructs the ear canal, causing symptoms like ear ringing, plugged feeling, earache, and temporary hearing loss.
- Swimmer's Ear: An outer ear canal infection that can occur after exposure to water, affecting the area from the eardrum to the outer ear.
