A contact lens is used either for therapeutic reasons, corrective purposes or as a cosmetic tool. With the recent advances in the manufacturing process of contact lenses, anybody can wear them, whether it is a bifocal, daily disposable or astigmatism-correcting lens.
For millions of people, contact lenses have proven to be a healthy vision option. However, it should be decided only after checking with an eye care professional. If the steps prescribed to removing, inserting and caring for them are rigidly followed the contact lens can be used without any trouble. To check the effectiveness or lack of it from the lens, check periodically with an eye care professional.
If a vision problem is identified and needs a vision correction, one of the viable options is wearing a contact lens. Right from infants who have vision problems at birth, young children, teenagers and all adults can wear contact lenses.
According to doctors, contact lenses are the best option for vision correction for athletes. Contact lenses can improve the vision skills such as perception of depth, awareness of the peripheral area, co-ordination of eye-foot/eye-hand. Since the contact lens stays in place under dynamic conditions, they offer a total advantage to the athletes. They also free them from the risk of glasses-related injuries.
According to many eye specialists, contact lenses, which are made of a firm plastic lens, may slow or control the progression of myopia or near sightedness. In contrast, conventional spectacles or soft contact lenses do not offer such advantages.
In 1971, when contact lenses were introduced it was an advanced technology and offered comfort not provided by the old-style spectacles. With the latest technology, it is now possible to get better corneal health, sharper vision and a longer life for the lens.
Contact lenses need cleaning and disinfecting every day. Due to the slick surface offering no scope for building up of deposits, there is no need for frequent enzyming, which is a type of extra-strength cleaner, used weekly, for the removal of stubborn deposits from contact lenses.
Daily disposal lenses are worn everyday and discarded without any need for maintenance. Weekly disposal contact lens should be cleaned during the night, soaked in a solution containing disinfectants, until they are removed for usage again.
Color of the eyes also can be changed by using soft contact lenses even if vision correction is not needed. However they are also a prescribed medical device and should be used under the guidance of an eyecare professional. These types of contact lenses are used mostly by theatre and film personalities to get a closer resemblance to the character portrayed by them.
