An Ocular Research claims that wiping contact lens cases with tissue paper reduces the contamination risks. According to the study; if you typically clean your contact lens cases with disinfectant and then let it air-dry there are higher chances of contamination.
Research study shows that using a branded multi-purpose disinfectant for cleaning, rinsing and rubbing the contact lens case and then tissue-wiping it before allowing it to air dry reduces the bacteria accumulation.
The air has several microorganisms floating in it. These bacteria may quickly cling on to the surface of the cases when wet. It is thus advised to tissue-wipe the contact lens case and let it air dry with faces down on a paper-towel.
Furthermore; “Rub, Rinse, Tissue-wipe & air dry” is up to four times more effective way of disinfecting contact lens cases than conventional “rinse & air dry”. Contact lens cases requires attention to hygiene. Contact lens cases should be cleansed & disinfected using the same disinfectant that disinfects the contact lenses. After every use, contact lens cases should be thoroughly cleansed. Additionally; the bio-film should be buffed away using a clean and new tooth brush every so often.
Eye care professionals suggests replacing contact lens cases every three months since the bio-film that hides in the cases may act as a reservoir for bacteria and speeds up the bacteria growth. Sterilizing contact lens cases is also an option but it should only be referred to when you unfortunately fail to replace your contact lens cases. Instead of throwing used contact lens cases; it will bring more pleasure to ingeniously recycle the used contact lens cases in 9 different ways.
