Contact lenses need to be replaced regularly, mainly because of lens wear. Use time, protein precipitation, operating mode and other factors will cause the aging of the lens, so that the life of contact lenses is imperceptibly shortened. Although not always visible to the naked eye, lenses can become less oxygenable, more prone to breakage, and can cause eye problems. So, how to do can extend the service life of contact lens effectively?
Most people are used to wearing lenses on their fingers, but contact lenses are thin and soft, which can easily be scratched by fingernails. Be sure to trim your nails regularly and try not to have long nails, as they can be infested with bacteria and can be extremely unhygienic.
In the process of wearing, the lipids and proteins secreted by human eyes will gradually form sediments and adhere to the lens. If they cannot be removed in time, they will accumulate on the lens for a long time, which will not only easily cause lens deterioration, but also become a breeding place for bacteria. Scrubbing after each lens removal is very important, and kneading by hand is gentler and more effective than any machine.
Note the use period of the nursing solution, after opening more than three months, the nursing solution lost the role of sterilization, can no longer clean the lens, more can not be used to save the lens. In addition, different brands of care solution must not be mixed use, if some chemical reaction, it may damage the lens.
But must note is, in the use cycle to do a good job of lens care and maintenance, can achieve the purpose of extending contact lens life, once the lens exceeded the shelf life, can not continue to use.
