Vision correction
Vision correction is a procedure that improves eyesight by changing how light enters the eye. It can treat common vision conditions such as:Â
- Myopia (nearsightedness):Â Objects nearby appear clear, while distant objects appear blurry.
- Hyperopia (farsightedness):Â Distant objects appear clear, while nearby objects appear blurry.
- Astigmatism:Â Objects at all distances appear blurry or distorted.
- Presbyopia:Â Age-related loss of up-close vision.
Vision correction can be achieved through:
- Glasses:Â A prescription for glasses corrects how light enters the eye.Â
- Contact lenses:Â A prescription for contact lenses corrects how light enters the eye.Â
- Surgery:Â Surgery can involve reshaping the cornea with a laser, or replacing the eye’s lens.Â
Some types of vision correction surgery include:
- Laser eye surgery:Â Uses a laser to reshape the cornea.Â
- LASIK surgery:Â Uses a laser to remove tissue from the cornea, then folds a flap back into place.Â
- Lens implant surgery:Â Inserts a lens into the eye to redirect focus.
