Properly fitted and maintained contact lenses do not cause red eyes. Redness typically indicates an underlying issue such as overwear, poor hygiene, or an improper fit that restricts oxygen to the cornea.
- Follow the specific wearing schedule prescribed by your eye care professional to avoid corneal hypoxia.
- Remove lenses immediately if you notice redness combined with pain or blurred vision.
- Clean and disinfect monthly or bi-weekly lenses daily to remove protein deposits and environmental allergens.
- Replace lenses according to their expiration date to prevent the buildup of bacteria.
- Avoid sleeping in contact lenses unless they are specifically cleared for overnight wear.
Redness is a signal from the eye that something is wrong. Continuing to wear lenses when eyes are red can lead to more serious complications like corneal ulcers.
