They are neither wrath nor lust but these sins could leave you with nasty eye infections.


In the midst of the hustle and bustle of our lives, the simple steps of taking off or putting on our contact lenses has become an instinctive routine to many of us. However what slips our mind is the fact that we are inserting an artificial plastic device into our very fragile membrane; a process that should not be easily overlooked.

5 SINS OF CONTACT LENS WEARERS

While contact lenses could be a wonderful invention allowing us to see our best while removing the hassle our glasses bring, having a plastic device inserted into your eye daily could potentially lead to things going wrong, very wrong. Think infections, ranging from redness to discharge and worse. It’s time we give our contact lenses a little more ‘respect’ and take note of the following sins which we subconsciously could be committing.

1. You don’t wash and dry your hands before handling your lenses


Hand washing could be the most important step of all. Our hands are the most exposed body part to germs. Imagine the countless things our hands come in contact with every day- laptops, door handles, food. These germs could easily transfer from our hands to our lenses and our eyes subsequently leading to bacterial infections.

The drying of our hands plays an equally significant role before handling our lenses. Water contains a certain bacteria called Acanthamoeba. These bacteria are deemed to be the most harmful to our eyes with the potential to cause serious damage. Therefore, your contact lenses should never be allowed to come in contact with water.

2. You top up yesterday’s contact lens solution


Topping up or reusing previous day’s solution could seem like a brilliant idea to save some money initially, yet it could easily become a senseless decision after you’ve spent a hefty sum of money on an eye specialist due to a nasty eye infection. Reusing your solution is like begging for a bacterial infection. This is because, the mixture depletes of its bacterial killing biocide every time you place your contact lens in. Reusing it will also mean using an ineffective cleaning solution with the residual bacterial from your contact lenses yesterday.

3. Rinsing your lens case with water


Washing your lens cases with water could seem to be a legit thought. However, as mentioned above, your contact lenses should never come into contact with water to avoid the presence of Acanthameoba. After putting on your contact lenses, rinse the
case with the lens solution and leave it to dry with the cap opened. Anything that can live in your eye would not be able to live in a dry case, thus eliminating all possible bacterial which could cause eye infections.

4. You did not cleanse your contact lenses by rubbing them


After removing the lenses, give your lenses a gentle rub in a circular motion for at least 5 seconds before popping them into your lens cases. Contact lens solutions are not designed to remove 100% of bacterial and the rubbing process would help dislodge the bacterial from the lenses to allow more efficient cleaning by the solution.

5. Reusing your contact lens after swimming


Reusing your contact lens after swimming

Due to the harmful effects of water on our eyes, it is not recommended for user to swim or even shower with their contact lenses to minimize the contact on our lenses with water. If you are unable to see while swimming without your lenses, it is recommended to use water proof goggles or prescribed goggles which corrects your eyes refractive error. If water were to enter your eyes in any situation, it is recommended to immediately remove and disinfect them, or to discard them.

If you avoid these 5 contact lens sins, you will not only be on your way to better eye health but constantly feel refresh even with your lenses on.
