Eye infections from contact lenses
Contact lenses are a convenient and practical solution for vision correction, but improper care and usage can lead to difficulties - most notably eye infections. Infections predominantly occur due to scrapes on the cornea (the clear front surface of the eye), oxygen deprivation, or contamination caused by poor hygiene practices. Failing to follow recommended care guidelines increases the risk of infections such as acanthamoeba keratitis.
What is acanthamoeba keratitis?
Acanthamoeba keratitis is a corneal infection caused by a microscopic organism commonly found in water, air, and soil. While it is rare, contact lens wearers are at higher risk of infection and, if left untreated, the infection can lead to visual impairment. Being aware of the symptoms will help you mitigate the risk of lasting damage to your eyes. The most common symptoms to look out for include:
- Severe or persistent eye pain and redness.
- Blurred vision or light sensitivity.
- A gritty sensation in the eye.
- Excessive eye watering.
If you notice these symptoms, stop wearing your contact lenses immediately and consult an optometrist such as the Eye Establishment in London. If possible, bring your lenses to your appointment, as they may help identify the source of the infection.
Protecting your eyes from acanthamoeba keratitis
As noted above, acanthamoeba keratitis is often a result of poor hygiene practices in relation to your lenses. Following some simple guidelines ensures you avoid some of the most common causes of this condition, which include:
- Improper storage and handling of contact lenses.
- Wearing lenses overnight if they’re not designed for extended wear.
- Using ill-fitting lenses, which can scrape the corneal surface.
- Cleaning lenses with tap water.
- Swimming or showering with lenses, exposing them to harmful microbes.
- A history of eye injury, as scratches provide a gateway for infection.
By understanding these risks, you can adopt better habits to protect your eye health.
Additional eye problems
In addition to acanthamoeba keratitis, there are several eye problems that can manifest through wearing both regular and coloured contact lenses. Each comes with their own particular symptoms and requires different treatment:
Bacterial keratitis: The most frequent infection among contact lens wearers, bacterial keratitis (or corneal ulcers) is typically caused by a form of bacteria known as pseudomonas aeruginosa. Symptoms include pain, redness, and impaired vision. Antibiotics are the standard treatment.
Viral keratitis: Caused by the herpes simplex virus (the same virus responsible for cold sores), viral keratitis can lead to irritation, redness, and discomfort. Treatment often involves cold compresses, eyedrops or antiviral medications.
Fungal eye infections: Although less common, fungal infections can occur due to improper lens storage or handling. Antifungal eyedrops are used to manage these cases, but early detection is key.

Eye infections are treatable when detected early, but prevention is always better than cure. By ensuring that you always handle your lenses with clean, dry hands; store lenses in fresh solution and replace cases regularly; avoid sleeping, swimming or showering with lenses; and never use tap water to clean them, you can help limit exposure to such issues. You can also liaise with the team at the Eye Establishment to schedule a contact lens review and to discuss any potential issues you may be having.
