Contact lenses are a simple and easy alternative to wearing spectacles. They offer freedom and flexibility, especially for people who live active lifestyles. However, they do require extra care and attention in handling and keeping the lenses clean to avoid bacterial infections.
Contact lenses are small, thin prescription lenses that are worn in “contact” with the eye. They are designed to correct refractive errors and maintain ocular health.
Contact lenses work by floating on a layer of tears that cover the cornea, with each blink, a fresh supply of oxygen-laden tears washes behind the lens to bathe and nourish the cornea. Since the lenses stick to the tear fluid on the eyes surface, they move naturally with your eye direction.
Contact lenses work to correct vision in the same way that spectacles do, they alter the direction of light rays to focus light properly onto the retina.
They are available in soft and hard lenses as well as daily, fortnightly or monthly disposable lenses.
