Are you tired of wearing those rose-tinted spectacles on your nose all the time? Then you should start wearing the contact lens to see the world in a different way. Contact lenses are thin, curved plastic disks that are designed to cover the cornea, the clear front covering of the eyes. These delicate objects cling to the film of tears over the cornea because of the surface tensions. So try out contact lenses as a great alternative to those monotonous eyeglasses.
Who wears contact lenses?
Contact lenses are medical devices that need to be properly fitted by an eye care practitioner. So you should visit an optician before you want to wear a contact lens. Contact lenses are wonderful items that are used to correct eye conditions like:
 Myopia [nearsightedness]
 Astigmatism [distorted vision]
 Hyperopia [farsightedness]
 Presbyopia [need for bifocals]
Contact lenses are also used in therapeutic cases where an uneven cornea blurs vision, such as scarring or keratoconus.
Types of contact lenses
Many types of contact lenses are available to suit particular occasions. Whether you want to wear contact lenses for fashionable purposes or for medical purposes, you can wear any of the following types:
 Gas-permeable lenses ? are lenses made of silicone and fluoropolymers that allow oxygen in the air to pass through the lens.
 Soft contact lenses ? are plastic materials that incorporate water. The water makes the lenses soft and flexible, which allows the oxygen to reach the cornea.
o Extended wear contact lenses ? last for continuous 2-4 weeks.
o Daily disposable lenses ? carry a very low amount of infection risk
o Toric contact lenses ? available in soft and rigid materials, they correct moderate astigmatism.
 PMMA lenses ? one of the old lenses that are very durable and allow oxygen from air to directly reach the cornea.
You should remove contact lenses at bedtime due to risk of infection.
