What Is Keratitis and Why Should You Care?
Keratitis refers to inflammation of the cornea, the clear dome that covers the front of your eye. This condition can result from various causes, including bacterial, viral, or fungal infections, as well as injuries or irritants. While anyone can develop keratitis, contact lens wearers face a significantly higher risk. The good news is that keratitis is largely preventable with proper eye care habits.
Understanding what keratitis is and how to prevent it can save you from painful symptoms and potential vision complications.
Causes of Keratitis: Know Your Risk Factors
Contact Lens-Related Keratitis
Contact lenses are the leading cause of keratitis, particularly when wearers:
- Sleep in contacts not designed for overnight use
- Wear your contacts beyond on the discard date of your brand/type
- Use expired or damaged lenses
- Don't clean lenses properly
- Swim or shower while wearing contacts
- Use tap water to rinse lenses or cases
The longer you wear contacts and the less careful you are about hygiene, the higher your risk becomes.
Infections from Bacteria, Viruses, and Fungi
Different microorganisms can infect your cornea:
- Bacterial Keratitis: Often linked to contact lens use, especially sleeping in lenses. Bacteria like Pseudomonas can cause rapid, severe infections.
- Viral Keratitis: Herpes simplex virus (the same virus that causes cold sores) commonly causes viral keratitis. This type can recur and cause progressive damage.
- Fungal Keratitis: Less common but serious, often resulting from eye injuries involving plant material or in people with weakened immune systems.
- Acanthamoeba Keratitis: A rare but severe infection from a parasite found in water. Contact lens wearers who expose their lenses to water are most at risk.
Other Causes of Keratitis
Beyond infections, keratitis can develop from:
- Eye injuries or scratches
- Exposure to ultraviolet light
- Contaminated eye drops
- Dry eyes
- Foreign objects in the eye
- Eyelid problems that prevent proper eye protection
Keratitis Symptoms: When to See a Doctor
Recognizing the Warning Signs
Keratitis symptoms can range from mild to severe and typically include:
- Eye pain or discomfort
- Redness
- Excessive tearing
- Light sensitivity (photophobia)
- Blurred vision
- Feeling like something is in your eye
- Discharge from the eye
If you wear contact lenses and experience any of these symptoms, remove your lenses immediately and contact an eye doctor.
Don't Wait—Seek Prompt Treatment
Keratitis can progress quickly, especially bacterial keratitis. What starts as mild irritation can become a serious infection within hours or days. Early keratitis treatment prevents complications like corneal scarring, chronic inflammation, or permanent vision loss.
Conestoga Eye provides medical eye care for conditions like keratitis. Don't hesitate to seek professional evaluation if you suspect an eye infection.
4 Essential Ways to Prevent Keratitis
1. Practice Proper Contact Lens Hygiene
If you wear contact lenses, following these habits dramatically reduces your keratitis risk:
- Wash Your Hands: Always wash and dry your hands thoroughly before touching your contacts or eyes. This simple step eliminates most bacteria that cause infections.
- Follow Replacement Schedules: Replace daily lenses every day, weekly lenses every week, and monthly lenses every month. Never overwear your lenses beyond their intended duration.
- Clean and Store Properly: Use only fresh contact lens solution (never tap water) to clean and store your lenses. Replace your lens case every three months.
- Never Sleep in Contacts: Unless you have lenses specifically approved for overnight wear by your eye doctor, always remove them before sleeping. Sleeping in contact lenses increases infection risk by 6-8 times.
- Remove Lenses in Water: Take out your contacts before swimming, showering, or using hot tubs. Water exposure is a major risk factor for Acanthamoeba keratitis.
2. Protect Your Eyes from Injury
Corneal injuries create entry points for infections. Prevent eye injuries by:
- Wearing safety goggles during yard work, home repairs, or activities with flying debris
- Using protective eyewear during sports
- Being careful with tree branches, fingernails, and other sharp objects near your eyes
- Wearing UV-protective sunglasses outdoors
If you do injure your eye, seek immediate medical attention even if it seems minor. Prompt treatment prevents infection and promotes healing.
3. Maintain Good Overall Eye Health
Healthy eyes resist infections better:
- Use Quality Eye Products: Only use eye drops and solutions recommended by your eye doctor. Contaminated products can introduce infections.
- Manage Dry Eyes: Keep your eyes well-lubricated with preservative-free artificial tears if you experience dryness. Dry eyes are more vulnerable to damage and infection.
- Don't Share Eye Products: Never share contact lenses, eye makeup, or eye drops with others. This spreads bacteria and viruses.
- Replace Eye Makeup Regularly: Throw out mascara and eyeliner every 3-4 months to prevent bacterial growth. Replace immediately if you develop an eye infection.
4. Get Regular Eye Exams
Routine eye examinations at Conestoga Eye help identify risk factors and early problems before they become serious. Your eye doctor can:
- Assess your contact lens fit and wearing habits
- Check for dry eyes or eyelid problems that increase infection risk
- Provide personalized recommendations for your specific situation
- Catch early signs of complications
Regular check-ups are especially important for contact lens wearers, who should have annual comprehensive exams.
Keratitis Treatment: What to Expect
How Long Does Keratitis Last?
Treatment duration depends on the cause and severity. Mild bacterial keratitis may resolve within a week with proper treatment, while viral, fungal, or Acanthamoeba keratitis can take weeks or months to heal. How long keratitis lasts also depends on how quickly you seek treatment, since early intervention shortens recovery time.
Treatment Options
Keratitis treatment varies based on the underlying cause:
- Bacterial Keratitis: Antibiotic eye drops, sometimes very frequent applications initially (every 30 minutes to hourly). Severe cases may require oral antibiotics.
- Viral Keratitis: Antiviral eye drops or oral medications, particularly for herpes infections.
- Fungal Keratitis: Antifungal medications, which can take much longer to work than antibiotics.
- Acanthamoeba Keratitis: Specialized antimicrobial drops used for extended periods.
- Non-Infectious Keratitis: Lubricating drops, anti-inflammatory medications, and addressing the underlying cause.
During treatment, you'll typically need to:
- Stop wearing contact lenses
- Use prescribed medications exactly as directed
- Attend follow-up appointments to monitor healing
- Avoid rubbing or touching your eyes

Frequently Asked Questions
What are the most common keratitis symptoms?
The most common keratitis symptoms include eye pain, redness, excessive tearing, sensitivity to light, blurred vision, and feeling like something is stuck in your eye. You may also experience discharge from the affected eye. Contact lens wearers who develop these symptoms should remove their lenses immediately and seek medical attention.
Can keratitis go away on its own?
Minor irritation from dry eyes or environmental factors may improve on its own, but infectious keratitis requires medical treatment. Bacterial, viral, fungal, and parasitic keratitis will not resolve without appropriate medications and can cause permanent vision damage if left untreated. Always have eye pain or vision changes evaluated by a professional.
How do you get keratitis?
The most common way people get keratitis is through improper contact lens use, including sleeping in lenses, poor hygiene, or water exposure while wearing contacts. You can also develop keratitis from eye injuries, viral infections like herpes simplex, contaminated eye products, or chronic dry eyes. Any break in the corneal surface can allow microorganisms to cause infection.
Is keratitis contagious?
Keratitis itself isn't contagious, but the viruses or bacteria that cause it can spread from person to person. For example, herpes simplex virus can spread through direct contact. Avoid sharing towels, eye makeup, contact lenses, or touching your infected eye and then touching others to prevent spreading the underlying infection.
How can I tell if my eye infection is serious?
Seek immediate medical attention if you experience severe eye pain, significant vision loss, intense light sensitivity, or rapidly worsening symptoms. Any eye infection in a contact lens wearer should be evaluated promptly, as bacterial keratitis can progress quickly. When in doubt, have any eye symptoms checked by a professional.
