Precaution while using Contact Lenses
Get a contact lens prescription from an eye doctor
Have your lenses fitted by a qualifiedeye care professional, says Steinemann. Also be sure to get instruction on proper lens care. Make sure that the contact lens is on the cornea of the eye. Cover the opposite eye, and if your vision is blurry, inspect the upper area of your eye by lifting the upper lid and looking into a mirror, and the lower area by gently pulling down the lower lid.
