Different contact lenses have different usage limits, however all should be worn in moderation. Whether you have daily, weekly, or monthly lenses, it is important not only to stick to the recommended replacement schedule, but also to take breaks in between daily use. If you leave your lenses in too long or go too long without replacing, you can put your eyes at serious risk of damage. Here are five reasons why your optometrist in Webster Groves, MO, recommends avoiding contact overuse.
1. Dry Eye
At the very minimum, contact overuse deprives your eyes of moisture and oxygen. Even gas-permeable lenses can limit oxygen over time. When this happens, you may notice dry, red eyes with varying degrees of discomfort.
2. Scratching and Tearing
If you go too long between the recommended replacement schedule, your contact lenses in Kirkwood, MO, can start to lose performance and comfort. Though it can happen with any kind of lenses, scratching and tearing of the cornea are most common with hard contacts.
3. Eye Strain
By giving your eyes a break and wearing eyeglasses once in a while, you also avoid the threat of eye strain. When they are routinely deprived of oxygen, eyes strain and can lead to headaches and even migraines.
Keratitis is an inflammation of the cornea, but it means much more than the presence of red eyes. When contacts are overused, keratitis can cause painful symptoms including redness, grittiness, sensitivity to light, watering, and blurred vision.
Perhaps one of the most sinister hazards posed by leaving your contacts in too long is the threat of a bacterial or fungal infection. If keratitis is caused by bacteria, in fact, severe cases can eventually lead to total blindness.
