lenses are reusable

Soft disposable lenses first appeared in the 1960s. They were made from soft plastic and draped over the cornea, conforming to the eye’s natural shape. Today, these lenses are reusable, lasting about a year. These lenses contain silicone-based plastics, which allow more oxygen to reach the cornea. However, they can cause a high level of irritation while being worn. The following are some tips to avoid these problems. A good solution is to thoroughly rinse the lens and to keep it in a case that is free of dust and debris.

For the removal of contact lenses, there are small tools available for this purpose. These devices are typically made of plastic and resemble small tweezers. Plungers suction onto the front of the lens. These tools are generally used with rigid lenses and require great care. Fingernails and mechanical tools should be used only with extreme caution. Cleaning contact lenses requires a solution of hydrogen peroxide. The solution is neutralised over time by a catalytic disc in the case. The cleaning schedule depends on the type of material, and some lenses are disposable, requiring no maintenance. Depending on the type of material, regular cleaning is necessary to avoid surface coating or infections.
