Eye Fatigue: Is It Glaucoma or Something Else? - Ophthalmology

Eye fatigue is a common issue that many people experience, especially those who spend long hours in front of screens or engage in activities that require intense focus. Your symptoms, including seeing colored halos around lights, a feeling of pressure or heaviness in the eyes, and frequent yawning, can be concerning. However, it's essential to understand that these symptoms do not necessarily indicate glaucoma.

Glaucoma is a group of eye conditions that damage the optic nerve, often due to high intraocular pressure (IOP). While some symptoms of glaucoma can include blurred vision, seeing halos around lights, and eye pain, it is crucial to consider the context of your symptoms. In your case, you have a significant degree of myopia (nearsightedness) and astigmatism, which can contribute to visual disturbances and discomfort.

The colored halos you see around lights, especially at night, can be attributed to several factors, including:
1. Refractive Errors: High myopia and astigmatism can cause light to scatter as it enters the eye, leading to visual distortions such as halos. This is particularly noticeable in low-light conditions.

2. Dry Eyes: Prolonged screen time can lead to dry eyes, which can cause discomfort and visual disturbances. When your eyes are dry, they may not focus light properly, resulting in halos and blurriness.

3. Eye Fatigue: Extended periods of focusing on screens can lead to eye strain, which may manifest as a feeling of heaviness or pressure in the eyes, along with frequent yawning as your body attempts to relieve the discomfort.

4. Cataracts: Although you are relatively young, cataracts can develop in individuals with high myopia. They can cause halos around lights and blurred vision, particularly at night.

5. Other Conditions: Conditions such as migraines or tension headaches can also lead to visual disturbances, including halos and eye discomfort.

Given your symptoms, it is advisable to consult an eye care professional for a comprehensive eye examination. They can measure your intraocular pressure and assess the health of your optic nerve to rule out glaucoma or other serious conditions.
In the meantime, here are some strategies to help alleviate eye fatigue:
- Take Regular Breaks: Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This helps reduce eye strain.

- Adjust Lighting: Ensure that your workspace is well-lit to reduce glare on screens. Consider using anti-reflective coatings on your glasses.

- Stay Hydrated: Drink plenty of water to help maintain moisture in your eyes.

- Use Artificial Tears: If you experience dry eyes, consider using lubricating eye drops to keep your eyes moist.

- Limit Screen Time: If possible, reduce the amount of time spent on screens, especially before bedtime.

- Proper Prescription: Ensure that your glasses or contact lenses are up to date, as an incorrect prescription can contribute to eye strain.

In conclusion, while your symptoms may be concerning, they do not automatically indicate glaucoma. A thorough examination by an eye care professional is essential to determine the cause of your symptoms and to ensure your eye health is maintained.
