WHAT IS REFRACTIVE ERROR?
A refractive error is a common vision problem that occurs when the shape of your eye prevents light from focusing properly on the retina, causing blurry vision. Over 150 million Americans have a refractive error, making regular eye exams essential for clear sight.
Types of Refractive Errors
→ An irregularly shaped cornea or lens causes blurry or distorted vision at all distances.
→ Can develop from genetics, eye disease, or past eye surgery.
→ Easily corrected with glasses, contacts, or refractive surgery.
Nearsightedness (Myopia)
→ Objects up close appear clear, but distant objects are blurry.
→ Often develops in childhood and may worsen over time.
→ Increased risk of retinal detachment, glaucoma, and cataracts in severe cases.
→ Distant objects are clearer than near ones.
→ Some people don’t notice symptoms until later in life.
→ Severe cases can lead to lazy eye (amblyopia) or crossed eyes (strabismus) if untreated.
Farsightedness (Hyperopia)
→ A normal part of aging, making it harder to see up close (usually after age 40).
→ Holding reading materials farther away can help.
→ Corrected with reading glasses, bifocals, contact lenses, eyedrops, or LASIK surgery.
