2025 Guide: Can COVID-19 Cause Blurry Vision? Understanding Eye Symptoms & Treatments

Most people recognize common COVID-19 symptoms such as fever, cough, and fatigue, but eye-related signs like blurry vision are less known. Can COVID-19 cause blurry vision directly? While the virus primarily infects through the nose and mouth, it can also enter via the eyes when contaminated droplets come into contact or through touching your eyes with unwashed hands.

COVID-19 itself isn’t known to directly cause blurry vision. However, it can trigger eye conditions like conjunctivitis (pink eye) and dry eye syndrome, which may result in blurred vision.

This comprehensive guide delves into these eye issues linked to COVID-19 and offers practical advice on prevention and treatment.

Is Blurry Vision a Direct Symptom of COVID-19?

Blurry vision is generally not a direct symptom of COVID-19. Instead, it often arises from secondary eye complications caused by the virus, including:

• Conjunctivitis (Pink Eye)
• Dry Eye Syndrome

Let's examine these conditions in detail.

Conjunctivitis and COVID-19

Conjunctivitis is inflammation of the conjunctiva, the tissue covering the white part of the eye and inner eyelids. It can be triggered by viruses, bacteria, or allergies.

Symptoms of conjunctivitis include:

• Blurry or hazy vision
• Redness and swelling of the eyes
• Itching or burning sensation
• Watery eyes
• Feeling of a foreign object in the eye
• Sensitivity to light

A 2021 meta-analysis identified conjunctivitis as the most common eye condition among COVID-19 patients with eye symptoms, though its overall incidence remains low (around 1.1%). Hospitalized patients may have a higher risk, with some studies reporting rates up to 11.6%.

Treatment Tips for COVID-19 Related Conjunctivitis

• Apply clean, cool compresses to reduce swelling and itching.
• Consult an eye specialist who may prescribe medicated eye drops or ointments.

Dry Eye Syndrome and COVID-19

Dry eye syndrome occurs when tear production is insufficient, leading to discomfort and sometimes blurry vision.

Common symptoms include:

• Burning or stinging eyes
• Redness and irritation
• Sensation of debris in the eyes
• Discomfort with contact lenses

Studies show dry eye is frequently reported among COVID-19 patients with eye complaints, affecting approximately 16% of those individuals.

Managing Dry Eye Symptoms

• Use artificial tear drops regularly.
• Apply warm compresses to soothe eyes.
• Use a humidifier to maintain indoor moisture.

If symptoms persist or worsen, seek professional eye care.

Other Rare Eye Complications Linked to COVID-19

Though uncommon, COVID-19 has been associated with other eye inflammations such as uveitis and episcleritis, as well as rare cases of retinal blood vessel blockages causing temporary vision loss. Patients with preexisting eye conditions like macular degeneration may be at higher risk of severe COVID-19 outcomes, but further research is needed.

Protecting Your Eyes from COVID-19 in 2024

• Wash your hands thoroughly and frequently to prevent virus transfer.
• Avoid touching your eyes with unwashed hands.
• Wear protective glasses to reduce exposure to respiratory droplets.
• If you use contact lenses, maintain strict hygiene or consider switching to glasses temporarily.
• Use cosmetics cautiously and never share eye makeup.

Recognizing Common COVID-19 Symptoms

Besides eye symptoms, typical COVID-19 signs include:

• Fever
• Cough
• Muscle pain
• Fatigue

Less frequent symptoms may be chills, loss of taste or smell, shortness of breath, headache, sore throat, nasal congestion, and digestive issues.

When to Seek Medical Attention

If you experience blurry vision alongside COVID-19, or symptoms like eye pain, redness, floaters, or vision loss, promptly consult an eye specialist.

Seek emergency care if you have serious signs such as difficulty breathing, chest pain, blue or pale skin, confusion, or severe fatigue.

Summary

While COVID-19 does not directly cause blurry vision, related eye conditions like conjunctivitis and dry eye syndrome can lead to blurred sight. Maintaining good hygiene, protecting your eyes, and consulting healthcare professionals when symptoms arise are essential steps to safeguard your eye health during the pandemic.
