Contact lenses are very safe. Still, wearing contact lenses can damage your eyes if you wear them too long, fail to clean them properly or do not replace them as directed by your eye doctor. Contact lenses are considered medical devices and are regulated by the U.S. Food and Drug Administration (FDA).
Contact lenses can improve vision for people with these refractive errors:
- myopia (nearsightedness)
- hyperopia (farsightedness)
- astigmatism (distorted vision)
- presbyopia (changes to near vision that normally happen with age)
