Does Prolonged 3C Device Use Increase Eye Pressure and Risk of Glaucoma? - Ophthalmology

Prolonged use of 3C devices, such as smartphones, tablets, and computers, has become increasingly common, especially among younger individuals. Your concerns about eye pressure and the risk of glaucoma are valid, particularly given your extensive screen time and the symptoms you are experiencing.
Firstly, it is essential to understand that while prolonged screen time can lead to discomfort and symptoms such as eye strain, dryness, and fatigue, it does not directly cause an increase in intraocular pressure (IOP) that leads to glaucoma. Glaucoma is primarily associated with elevated IOP, but it can also occur in individuals with normal eye pressure. The condition is often related to the health of the optic nerve and can be influenced by various factors, including genetics, age, and existing health conditions.

In your case, the fact that you have had your eye pressure checked and it was found to be normal is reassuring. However, it is important to note that symptoms like eye swelling, pain, and discomfort can arise from several factors, including improper prescription of contact lenses, prolonged near work, and inadequate lighting conditions. Your doctor mentioned that your contact lens prescription is higher than your actual prescription, which could contribute to eye fatigue and discomfort. It would be advisable to address this issue by getting a proper eye examination and possibly adjusting your prescription.

Regarding the use of 3C devices in low-light conditions, while it may not directly cause glaucoma, it can lead to increased eye strain and discomfort. When using screens in dim lighting, your eyes have to work harder to focus, which can exacerbate symptoms of fatigue and strain. This is often referred to as digital eye strain or computer vision syndrome, which can manifest as blurred vision, dry eyes, and headaches.

To mitigate the effects of prolonged screen time, consider the following strategies:
1. Follow the 20-20-20 Rule: Every 20 minutes, take a 20-second break to look at something 20 feet away. This helps reduce eye strain.

2. Adjust Lighting: Ensure that your workspace is well-lit to reduce glare on your screens. Avoid using devices in very dim light.

3. Proper Prescription: Make sure your glasses or contact lenses are correctly prescribed to avoid unnecessary strain.

4. Use Artificial Tears: If you experience dryness, using lubricating eye drops can help alleviate discomfort.

5. Limit Screen Time: Try to reduce the amount of time spent on screens, especially for non-essential activities.

6. Regular Eye Exams: Regular check-ups with an eye care professional are crucial, especially given your family history of hypertension and diabetes, which can affect eye health.

In summary, while prolonged use of 3C devices does not directly cause glaucoma, it can lead to symptoms that may mimic or exacerbate existing eye conditions. Maintaining proper eye care practices and regular check-ups will help ensure your eyes remain healthy. If you continue to experience discomfort or have concerns about your eye health, it is essential to consult with an eye care professional for a comprehensive evaluation.
