Hello! Thank you for your question regarding the changes in your eyeglass prescription. It’s understandable that with your busy academic schedule and late nights, you might be concerned about your vision and the accuracy of your recent eye exam.

Firstly, it’s important to note that fluctuations in your eyeglass prescription can occur for several reasons. The increase of approximately 50 degrees in your prescription could be attributed to a few factors:
1. Eye Strain and Fatigue: Prolonged use of computers, especially late into the night, can lead to digital eye strain, also known as computer vision syndrome. Symptoms include blurred vision, dry eyes, and discomfort. This strain can temporarily affect your vision, making it seem like your prescription has changed. If your eyes are fatigued during the exam, it may lead to an inaccurate measurement.

2. Different Testing Conditions: If you had your eyes examined by different optometrists, variations in testing conditions could lead to discrepancies in your prescription. Factors such as lighting, the equipment used, and even the time of day can influence the results. It’s best to have your eyes checked under similar conditions for consistency.

3. Natural Changes in Vision: It’s also possible that your vision has genuinely changed. Factors such as age, health conditions, and lifestyle can all contribute to changes in your eyesight. For instance, if you are experiencing more stress or fatigue, this could exacerbate any underlying refractive errors.

4. Relaxation of the Eyes: When you have your eyes examined, it’s crucial that your eyes are relaxed. If you were using your glasses frequently before the exam, your eyes might not have had enough time to relax, leading to a potential overestimation of your prescription. It’s advisable to take breaks from screens and give your eyes time to rest before an eye exam.

5. Prescription Accuracy: If you suspect that the new prescription is incorrect, consider getting a second opinion from another optometrist. They can perform a comprehensive eye exam and confirm whether the new prescription is appropriate for your needs.

To mitigate eye strain while studying, consider the following tips:
- Follow the 20-20-20 Rule: Every 20 minutes, take a 20-second break and look at something 20 feet away. This helps reduce eye fatigue.

- Adjust Your Workspace: Ensure that your computer screen is at eye level and about an arm's length away. Proper lighting can also reduce glare on your screen.

- Use Artificial Tears: If you experience dryness, using lubricating eye drops can help keep your eyes moist.

- Limit Screen Time: Whenever possible, try to limit your screen time, especially late at night. This can help reduce strain and improve your overall eye health.

In conclusion, while a change in your eyeglass prescription can be concerning, it’s essential to consider various factors that could contribute to this change. If you continue to experience discomfort or if your vision seems to worsen, I recommend consulting with an eye care professional for a thorough evaluation. They can provide you with the best advice tailored to your specific situation. Take care of your eyes, especially during your studies, and ensure you’re giving them the rest they need!
