Glare in Eyes: Impact of Screen Time and Reading Habits - Ophthalmology

More Info

Glare and visual discomfort from prolonged screen time are common issues faced by many individuals, especially those who frequently use electronic devices. Your concern about experiencing glare, particularly in the evening, is valid and can stem from several factors, including screen brightness, ambient lighting, and the duration of screen exposure.
When you spend extended periods looking at screens, your eyes are subjected to a constant strain, which can lead to symptoms such as glare, dryness, and fatigue. The glare you experience may not necessarily be related to high intraocular pressure (IOP), but rather to the way your eyes are processing light from screens. High IOP is typically associated with conditions like glaucoma, which requires specific medical evaluation and management. If your eye doctor has ruled out significant issues related to your eye health, it may be more about how your eyes are reacting to prolonged screen exposure.

Switching to reading books instead of using screens can indeed help alleviate some of the discomfort associated with glare. Reading physical books generally involves less strain on the eyes compared to screens, especially if you ensure that the lighting is adequate. Good lighting can help reduce glare and make reading more comfortable. However, it’s essential to maintain a proper distance from the text and ensure that your reading environment is well-lit to avoid straining your eyes.

Regarding your concern about whether reading can cause an increase in eye pressure, reading itself does not typically lead to elevated intraocular pressure. However, if you are straining to see the text due to uncorrected vision problems, this can lead to discomfort and fatigue. It’s crucial to have your vision corrected appropriately with the right prescription glasses or contact lenses. If your glasses are too strong or not suitable for your current vision needs, this could contribute to visual discomfort, including glare.

To improve your overall eye comfort, consider the following tips:
1. Adjust Screen Settings: Lower the brightness of your screens to a comfortable level. Use blue light filters or night mode settings to reduce glare, especially in the evening.

2. 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.

3. Maintain Proper Lighting: Ensure that your reading area is well-lit. Avoid reading in dim light, as this can cause your eyes to work harder.

4. Stay Hydrated: Drink plenty of water to keep your body and eyes hydrated, which can help reduce dryness and discomfort.

5. Consider Eye Exercises: Simple eye exercises can help alleviate strain. For instance, rolling your eyes or focusing on distant objects can help relax the eye muscles.

6. Regular Eye Exams: Keep up with regular eye exams to ensure that your prescription is up to date and to monitor your overall eye health.

7. Limit Screen Time: If possible, reduce the amount of time spent on screens, especially before bedtime, to help your eyes recover.

In conclusion, while switching to reading books may help reduce glare and discomfort, it’s essential to ensure that your vision is corrected appropriately and that you maintain good eye care habits. If symptoms persist or worsen, consider seeking further evaluation from an eye care professional to rule out any underlying conditions.
