Uneven Eye White Color: Causes and Solutions for Eye Discomfort - Ophthalmology

Share to:

The sclera of the two eyes is different in color?


Hello Doctor: Due to my high myopia and work requirements, I have to wear contact lenses.
I have been accustomed to wearing them for many years.
However, recently I have been experiencing some discharge from my eyes (perhaps eye mucus!).
Sometimes they also feel itchy and have a stinging sensation.
When I take off my glasses, it feels even more uncomfortable, and I have difficulty opening my eyes.
I also noticed that the color of the sclera is uneven; one eye has a clearer blue-white sclera, while the other appears off-white with a yellowish tint and looks more opaque.
I'm not sure what is happening.

Prolonged use of contact lenses can lead to complications such as conjunctivitis, dry eye syndrome, and corneal infections.
Therefore, please seek a nearby ophthalmologist for diagnosis and treatment.

Uneven eye white color, or scleral discoloration, can be concerning, especially when accompanied by discomfort such as itching, tearing, or pain. Given your history of high myopia and long-term contact lens use, several factors could contribute to the symptoms you're experiencing.

Firstly, the uneven color of the sclera (the white part of the eye) can be attributed to a variety of causes. One common reason for a yellowish tint in one eye could be related to the presence of a pinguecula or pterygium, which are growths on the conjunctiva (the clear membrane covering the white part of the eye). These growths can occur due to prolonged exposure to UV light, dust, and wind, and they may cause irritation or discomfort, especially in contact lens wearers.

Another possibility is the development of conjunctivitis, which can be allergic, viral, or bacterial in nature. Allergic conjunctivitis often presents with redness, itching, and tearing, while bacterial conjunctivitis can lead to discharge and discomfort. If you are experiencing discharge, it is crucial to consult an eye care professional for a proper diagnosis and treatment.

The discomfort you describe, including the sensation of your eyes being unable to open and the presence of discharge, may also indicate dry eye syndrome, which is common among contact lens users. Prolonged wear of contact lenses can lead to decreased tear production or increased tear evaporation, resulting in dryness, irritation, and a feeling of grittiness. This condition can also contribute to the uneven appearance of the sclera, as dryness can cause inflammation and redness.

To address these issues, it is essential to take the following steps:
1. Consult an Eye Care Professional: Given your symptoms, it is vital to see an ophthalmologist or optometrist. They can perform a thorough examination to determine the underlying cause of your symptoms and recommend appropriate treatment.

2. Proper Contact Lens Hygiene: Ensure that you are following proper hygiene practices when handling and wearing your contact lenses. This includes washing your hands before touching your lenses, using the correct cleaning solutions, and not exceeding the recommended wear time for your lenses.

3. Consider Switching to Glasses: If you are experiencing significant discomfort with your contact lenses, consider taking a break and wearing glasses instead. This can help alleviate symptoms of dryness and irritation.

4. Use Artificial Tears: Over-the-counter artificial tears can help lubricate your eyes and relieve dryness. Look for preservative-free options, especially if you plan to use them frequently.

5. Evaluate Environmental Factors: If you work in a dry or dusty environment, consider using a humidifier or taking breaks to rest your eyes. Protecting your eyes from wind and UV exposure can also help prevent further irritation.

6. Monitor for Changes: Keep an eye on any changes in your symptoms or the appearance of your eyes. If you notice worsening symptoms or new developments, seek medical attention promptly.

In summary, the uneven color of your eye whites, along with the discomfort you are experiencing, could be related to several factors, including dry eye syndrome, conjunctivitis, or growths on the conjunctiva. It is crucial to consult with an eye care professional for an accurate diagnosis and tailored treatment plan. Taking care of your eye health is essential, especially as a contact lens wearer, to prevent complications and maintain comfort.
