Ayurvedic Wisdom
नेत्रे शुक्रं प्रजायेत यदा दोषाः प्रकुपिताः। रक्षेत् दृष्टिं विशेषेण पथ्याहारविहारतः॥
netre śukraṃ prajāyeta yadā doṣāḥ prakupitāḥ, rakṣet dṛṣṭiṃ viśeṣeṇa pathyāhāravihārataḥ.
When the humours become aggravated, cloudiness or affliction may arise in the eye. One should protect the vision with special care through wholesome diet and lifestyle.
Symptoms of Keratitis
- Redness of the eye, often pronounced and persistent
- Eye pain or a sharp, burning sensation in or around the eye
- Sensitivity to light (photophobia), making it uncomfortable to be in bright environments
- Blurred or hazy vision that does not clear with blinking
- A sensation of having something gritty or foreign in the eye
- Excessive watering or discharge from the affected eye
- Swelling around the eye or eyelids
- In some cases, a visible white or grey spot on the cornea
Causes of Keratitis
- Bacterial infection, often linked to improper contact lens use, eye injury, or contaminated eye drops
- Viral infections, particularly herpes simplex virus or herpes zoster (shingles affecting the eye)
- Fungal infection, more common after eye trauma involving plant material, soil, or organic matter
- Parasitic infection, such as Acanthamoeba, frequently associated with swimming in natural water while wearing contact lenses
- Dry eyes or reduced tear production, which can weaken the cornea's natural defences
- Nutritional deficiency, particularly of vitamin A, which is essential for maintaining healthy corneal tissue
- Overexposure to ultraviolet (UV) light, such as from sunlight or welding arcs without eye protection
- Immune system disorders or conditions that reduce the body's ability to fight eye infections
Diet for Keratitis
- Include foods rich in vitamin A, such as carrots, sweet potatoes, leafy greens, and orange-coloured fruits, to support corneal health
- Eat omega-3 fatty acid-rich foods like flaxseeds, walnuts, and oily fish to help maintain healthy tear film and reduce dryness
- Opt for antioxidant-rich fruits and vegetables — berries, citrus fruits, and leafy greens — to support eye tissue resilience
- Ensure adequate zinc intake through foods like pumpkin seeds, lentils, and chickpeas, as zinc plays a role in eye health
- Stay well hydrated throughout the day, as proper fluid intake supports natural tear production and overall eye moisture
- Include vitamin C-rich foods such as bell peppers, amla (Indian gooseberry), and tomatoes to support immune function and tissue repair
- Choose light, easy-to-digest meals during recovery to support the immune system without overburdening digestion
Foods to Avoid in Keratitis
- Limit excessive alcohol consumption, which can impair immune function and slow the body's natural recovery processes
- Reduce intake of highly processed and packaged foods high in refined sugars, which may dampen immune response
- Avoid excessive caffeine, as it can contribute to dehydration and may worsen dry eye symptoms
- Limit very salty or preserved foods, which may affect fluid balance and contribute to eye dryness
- Avoid very spicy or heavily seasoned meals if they seem to aggravate discomfort or increase facial flushing
- Reduce consumption of trans fats found in fried or commercially baked goods, as these may promote inflammatory processes
Prevention of Keratitis
- Always wash hands thoroughly before touching your eyes, handling contact lenses, or applying eye drops
- Follow safe contact lens practices: never sleep in lenses, replace them as directed, and use only sterile lens solutions
- Never share eye make-up, contact lenses, eye drops, towels, or face cloths with others
- Protect eyes from UV radiation by wearing quality sunglasses outdoors and appropriate goggles when using tools or working with organic materials
- Avoid swimming or using hot tubs while wearing contact lenses, as water can harbour microorganisms that infect the cornea
- If you work in dusty or agricultural environments, wear protective eyewear to prevent corneal abrasions and foreign body exposure
- Ensure a diet adequate in vitamin A and zinc to support the cornea's natural defence mechanisms
- Seek prompt attention for any eye injury, redness, or irritation rather than waiting for symptoms to worsen
When to See a Doctor for Keratitis
- Seek immediate medical attention if you experience sudden, severe eye pain combined with significant vision loss — keratitis can threaten sight if untreated
- Consult a qualified healthcare professional promptly if eye redness, pain, or light sensitivity does not improve within 24 hours
- Seek urgent care if a visible white or grey spot appears on your cornea, as this may indicate a rapidly progressing infection
- Do not delay professional evaluation if you wear contact lenses and develop any eye pain or redness — contact lens-related keratitis can worsen very quickly
- See a doctor if discharge from the eye becomes thick, yellow, or green
- Consult a qualified healthcare professional if blurred vision persists or worsens at any point
- Go to the nearest emergency department if the eye becomes extremely swollen, you lose vision in that eye, or pain is severe and unrelenting
- Remember that home remedies and herbal approaches are supportive only — they must never replace or delay professional medical treatment for keratitis
Herbal & Home Remedies for Keratitis
- Rest your eyes as much as possible, avoiding prolonged screen time, reading in poor light, or activities that strain the eyes
- Apply a clean, cool compress gently over closed eyelids to help soothe discomfort and reduce the sensation of heat around the eye — never apply pressure directly to the eyeball
- Maintain consistent hydration by drinking adequate water throughout the day to support healthy tear film production
- Keep the eye area clean by gently wiping away any discharge with a fresh, clean, damp cloth — always use a separate cloth for each eye and do not reuse
- If indoor air is very dry, a clean humidifier in the room may help reduce eye dryness and irritation
- Avoid rubbing the eyes, as this can worsen irritation and introduce additional microorganisms to an already vulnerable corneal surface
Home Remedies for Keratitis
- Rest in a dimly lit environment or wear tinted glasses indoors if light sensitivity is causing significant discomfort
- Remove and refrain from wearing contact lenses until symptoms have fully resolved and a healthcare professional has confirmed it is safe to resume use
- Protect the affected eye from dust, wind, and direct sunlight by wearing wraparound sunglasses when outdoors
- Ensure adequate sleep, as the body carries out much of its natural repair and immune activity during rest
- Avoid swimming pools, hot tubs, or natural bodies of water while symptoms persist, as these may introduce additional microorganisms to the eye
- Keep a consistent daily routine to support immune resilience, including regular meals, gentle movement, and adequate rest

Frequently Asked Questions About Keratitis
What is keratitis?
Keratitis is an inflammation of the cornea — the clear, dome-shaped layer at the front of the eye. It can be caused by infections (bacterial, viral, fungal, or parasitic) or by non-infectious factors such as dry eyes, UV exposure, or nutritional deficiencies. Because the cornea is central to clear vision, keratitis should be taken seriously and assessed by a healthcare professional promptly to prevent complications.
Is keratitis a serious condition?
Yes, keratitis can be serious. While mild cases may resolve with appropriate care, untreated or severe keratitis can lead to corneal scarring, chronic vision problems, or even permanent vision loss. The seriousness depends largely on the cause, how quickly it is identified, and whether appropriate professional care is sought without delay. Early assessment is always advisable.
Is keratitis contagious?
Certain types of keratitis — particularly those caused by viruses such as herpes simplex — can spread through direct contact with infected secretions. Bacterial forms may also pass between individuals through shared personal items. However, not all types are contagious. Practising good hand hygiene, not sharing towels or eye drops, and avoiding direct eye contact when infection is active can reduce the risk of transmission.
How long does recovery from keratitis take?
Recovery time varies depending on the cause and severity. Mild bacterial keratitis may begin to improve within days of appropriate care, while viral or fungal forms can take several weeks or longer. Severe cases involving corneal scarring may have a longer recovery. A qualified eye care professional is best placed to advise on expected timelines based on individual circumstances.
Can keratitis come back after it has healed?
Yes, certain types of keratitis — especially herpes simplex viral keratitis — are known to recur. Stress, illness, sun exposure, and immune changes can trigger recurrence. Individuals who have experienced keratitis should remain vigilant about eye health, follow any guidance from their eye care professional, and seek prompt attention if familiar symptoms reappear.
Can contact lens wearers get keratitis?
Contact lens wearers are at increased risk of keratitis, particularly if lenses are worn overnight, used beyond their recommended lifespan, or cleaned with tap water rather than sterile solution. Acanthamoeba keratitis — a particularly serious form — is strongly linked to contact lens use in contaminated water. Following safe lens hygiene practices significantly reduces this risk.
Can children develop keratitis?
Yes, children can develop keratitis, though the causes may differ from those in adults. Viral causes such as herpes simplex are seen in younger individuals, and eye injuries from play or foreign objects can also lead to infection. Any child with persistent eye redness, pain, light sensitivity, or changes in vision should be assessed by a qualified healthcare professional without delay.
Can Ayurveda support eye health in keratitis?
Ayurveda offers a range of traditional herbs and formulations traditionally associated with eye wellness and immunity, which some practitioners may consider as supportive care alongside professional medical treatment. However, keratitis is a condition that requires professional medical assessment and care. Herbal or Ayurvedic approaches should never replace or delay conventional treatment, particularly for infectious or rapidly worsening keratitis. Always consult a qualified Ayurvedic vaidya and an eye specialist.
