Contact lenses have made life rather easy for all those with weak eyesight. People have been using them for a long time, with some for over 20 years.
Governmental organisation Centre of Disease Control and Prevention has warned people time and again of misusing contact lenses and the consequences of applying them in an improper manner. Here are a few things that that you should never do if you wear contact lenses.
Improper use of contact lenses leads to severe eye infection and might even cause the user to lose his/her eyesight. 20% of cases of eye infection, in the US, are caused by use of contact lenses. Ophthalmologist Mark Former of Lenox Hill Hospital, New York, said: “There is serious health crisis with contact lens-related eye injuries. Unfortunately, a majority of over 41 million contact lens users in the United States do not think of it as a medical device that they are placing on the surface of their eye.”
1. Sleep wearing contacts lenses
Dozing off with contact lenses increases the risk of eye-infection by six fold. Sleeping with lenses on prevents the cornea from absorbing the much needed oxygen, which in turn causes irritation and redness in the eyes, along initiating other infections.
2. Using lenses over the expiry date
Do not use your weekly or monthly lenses after their expired date. There is a reason those lenses have an expiry date, in the first place. Over a certain time, lenses accumulate germs and bacteria on them, which are too strong, even for the solution to get rid of. If used for longer, these bacteria start to react with the eyes causing infection.
3. Don’t mix old solution with the new solution
Mixing an old solution that you’ve already been using, with a new one, makes the new solution lose the strength to fight germs. This, then, results in your lenses failing to get properly cleared, as they should before you use them.
4. Change them as and when the doctor prescribes
Your doctor knows the condition of your eyes and will be a better judge to inform you about the duration of using contact lenses.
5. Don’t swim with them
Diving into a pool with contacts on is like inviting trouble. The chlorine and the germs present in the pool, react with the lense and its solution, resulting in severe infections and other fatal conditions.
