Contact lenses are an effective form of vision correction which has made life easier for many people. But improper wear and care of contact lenses can cause so much damage. For all contact lenses users, it is important to have knowledge about the safety measures and also what common mistakes you may be making. This will help you avoid mistakes in the future and protect your vision.
Here are the common mistakes people make with contact lenses that could damage your eyes.
1. Wearing Contacts for Too Long: Wearing contacts for too long is bad for your vision health. It can lead to permanent scarring and even loss of vision. Contacts sit on top of your corneas, which do not have blood vessels to bring oxygen to them. It is the tears that do this important job. But tears cannot reach your corneas while you’re wearing contacts, as they act as a shield. By removing your contacts from time to time, you allow oxygen to reach the corneas. Prolonged wearing of contacts also makes your corneas more vulnerable to germs.
2. Sleeping in Your Contacts: Many people use to sleep with their contacts, which is not safe. Extended wear deprives the corneas of oxygen, which can lead to irritation and discomfort, and even a serious infection. In fact, it is common for users who sleep with their lenses in to wake up with dry eyes and blurry vision.
3. Wearing Your Contacts in Water: Swimming and showering in your contacts can be harmful because most water sources can actually irritate your eyes. In the recent CDC report, researchers found lenses are susceptible to absorbing water and can swell with the impurities and microorganisms found in the tap, which can change the lens shape entirely. In addition, most water sources include the microorganism Acanthamoeba, which can cause an extremely painful infection and may lead to blindness.
4. Wearing Your Contacts Past the Expiration Date: Old lenses become coated with germs and the build-up of the solution, proteins, and other residues. This makes lenses uncomfortable to wear and can lead to infection. You might think that you are saving money by wearing your old contact lenses for a long time, but you are actually calling for expensive medical bills.
5. Not Replacing Your Contacts case: Contact lenses cases should be cleaned thoroughly with the solution every day, and replaced at least every three months, according to the The American Optometric Association. Using an old case can lead to germs growing on the case and on the lens.
