Acanthamoeba is a parasite found in all water sources. If it gets into the eyes, it can be devastating. Always clean your contacts with a contact solution, never water. Also avoid wearing lenses in pools and hot tubs. Contacts are thinner, lighter and easier to wear than ever before. But, they still require healthy habits, and that includes taking them out before sleeping.
After reading this, we think you will! Your cornea is deprived of oxygen. The lenses act as petri dishes. You raise your risk of keratitis. Remember: contact lenses are not one-size-fits-all devices and therefore should never be bought over-the-counter OTC. Bringing your lenses to eye doctor can help them pinpoint the cause of the complications when you see them for an eye exam.

All Rights Reserved. New Patient Returning Patient. Most modern extended wear lenses are now made with silicone hydrogel materials that allow significantly more oxygen to pass through the lenses to your corneas than previous EW lenses.
This decreases the risk of hypoxia that makes the cornea more susceptible to inflammation and infection. Nearly all soft lenses prescribed for extended wear today are disposable contacts that are designed to be discarded after one to four weeks of use.
More frequent replacement of EW lenses reduces the build-up of proteins, lipids and other lens deposits that cause eye inflammation and discomfort and create a hospitable environment for the growth of infection-causing microorganisms. Extended wear lenses also are available in rigid gas permeable GP lens materials. Some eye care practitioners prefer GP lenses for extended wear because these rigid lenses cover less of the eye. Also, extended wear GP lenses move more freely with each blink, so there's less risk of debris and infection-causing microbes getting trapped under the lenses.
To further reduce risks of continuous wear of contact lenses, many eye care practitioners are recommending "flexible wear" of extended wear contacts rather than wearing the lenses for several days without a break. In flexible wear, disposable EW lenses usually are removed at night before sleep, but can be worn overnight occasionally — during a weekend camping trip, for example, or for daytime naps.
Though flexible wear is not quite as convenient as extended wear proper lens care using an approved contact lens solution is required each time the lenses are removed , it may be less risky than full extended wear. Despite these extended wear safety improvements, wearing contact lenses during sleep still carries a greater risk of complications than removing your lenses daily.
For this reason, most eye care practitioners now recommend daily disposable contact lenses as the preferred alternative to extended wear lenses. Though daily disposables aren't quite as convenient as extended wear lenses, removing and discarding these lenses after each use eliminates risks associated with sleeping with contact lenses on your eyes.
