Contact Lenses News and Research

RSS

Contact lenses are explicitly designed optical devices that can be worn directly on the cornea of the eye. People with poor eyesight wear contact lenses, which helps to refocus oncoming light rays on the retina to achieve a clear vision. Contact lenses increase or decrease the focusing potential of the cornea, and thereby directly project light onto the retina and aid in treating refractive errors.
