Common "Contact Lens" queries answered by top doctors | iCliniq

Contact Lens

Contact lenses are very thin and are placed directly on the surface of the eyes (cornea), which helps to improve vision. Contact lenses are made of plastics and are of two types, namely hard and soft contact lenses. They aid in correcting refractive vision problems such as myopia (nearsightedness), hyper myopia (farsightedness), astigmatism (distorted vision), and presbyopia (changes in the vision that occurs with age).
