Contacts affect the ability of your eyes to receive oxygen. This can cause them to become inflamed and uncomfortable, due to how your cornea is expanding, an ailment known as “keratitis.” As a result of keratitis, bacteria have a better chance of attacking the eyes. Those with keratitis have to cope with reddened eyes and a compromised vision. Instead of helping them to see, contacts have instead impaired their vision. In addition to not sleeping in contacts, you should also wash yours well and dispose of them when it’s become clear that they’ve surpassed their usefulness.
2. Trouble Wearing Contacts
Because of how wearing contacts overnight distorts the physicality of your eyes through inflammation and other conditions such as giant papillary conjunctivitis, you could end up with your contacts failing to stay on. There’s also a worst-case scenario possibility in which your eyes are affected to the point that wearing contacts is completely out of the question. If you can’t be responsible with your contacts, you’ll eventually find that you’ll have no use for them.
3. Corneal Neovascularization
Wearing contacts while sleeping can cause conditions that are cosmetically undesirable and seriously hazardous, such as corneal neovascularization. As a result of your eyes being starved for oxygen, your corneas start to develop additional blood vessels. This can give your eyes the unattractive “bloodshot” appearance. Not only that, your eyes could become seriously harmed, up to an including vision loss.
If you haven’t yet been convinced of the dangers of sleeping in your contacts, then the possibility of blindness should certainly snap you out of apathy. Every time you sleep in your contacts, you’re taking a gamble with your vision. Though conditions can be treated if caught in them, it makes absolutely no sense to risk your ocular health just so you can get to bed faster. Before you even think about getting into bed or closing your eyes for even a second, remove your contacts. There is a time and a place for everything, and contacts have no business being worn while you’re asleep.
Not sleeping in your contacts is as important as putting them in when you wake up. Your eyes need to be protected, and the ill effects of not removing your contacts are far greater than the short-term comfort of keeping them in and going right to bed. When you use contacts properly, your vision can be in optimal condition.
