Some 135 million people around the world wear contact lenses to correct vision irregularities, according to the Mayo Clinic. Contact lenses are minuscule plastic discs that are placed on the eye. According to Eye Topics.com, disposable contact lenses became available for commercial distribution in 1987. In 1995, daily-use disposable contact lenses were introduced. Disposable lenses have become the most popular type of contact lens.
Definition
Disposable contact lenses are worn only once and then discarded. AllAboutVision.com defines disposables as contact lenses that can be replaced daily or for a period not to exceed two weeks. Daily-use disposable contacts generally are more expensive than those that can be worn for an extended period of time.
Eye Health
Replacing your contact lenses frequently helps maintain your overall eye health, according to AllAboutVision.com. Deposits from calcium, protein and other substances can build up on longer-wear contacts that can make your eyes more vulnerable to infection. The use of disposable contacts prevents the accumulating of dirt and other residue from coming into contact with your eyes. Although there are cleaning solutions available for non-disposable contacts, some debris may remain on the lenses and collect over time.
Convenience
Many people with vision correction needs prefer the convenience of disposable contact lenses, according to LensContact.co.uk. Because disposables are thrown away after a short period of time, there is no need to bother with cleaning your contacts. The Mayo Clinic says a sufficient amount of cleaning solution for one day of use is included the disposable lens container.
Comfort
Disposable contact lenses are comfortable and are fitting for people whose eyes are sensitive to contact lens cleaning solutions. Disposable contacts can be a good choice for people who work in dusty conditions because irritants won't continuously collect on the lenses.
Precautions
ContactLensDocs.com says people should not attempt to reuse a disposable lens beyond the recommended time period. Make sure to schedule regular eye examinations. If your eyes become red and/or irritated, remove your disposables at once and contact your eye doctor.
