Hello! Thank you for your questions regarding rapid vision changes and eye pressure concerns. Let’s address your inquiries one by one.

1. Rapid Changes in Vision: It is indeed concerning to see a significant increase in your right eye's prescription, especially if it has increased by 100 degrees in just three months. While it is possible for myopia (nearsightedness) to progress, especially in individuals with high myopia, such a rapid change could also be influenced by several factors. Lack of sleep, such as staying up late to finish reports, can lead to temporary visual disturbances, including eye strain and fatigue, which might make your vision seem worse. Stress and prolonged near work can also exacerbate these symptoms. However, if the increase in your prescription is confirmed by a professional examination, it is advisable to monitor this closely. Regular check-ups with an eye care professional are essential, especially for individuals with high myopia, as they are at a higher risk for complications such as retinal detachment or other ocular issues.

2. Eye Pressure Measurements: Your eye pressure readings of 20 mmHg in the left eye and 21 mmHg in the right eye are within the normal range, but they are on the higher end of what is considered acceptable. Normal intraocular pressure (IOP) typically ranges from 10 to 21 mmHg. However, it’s important to note that what is considered "normal" can vary from person to person. Factors such as corneal thickness, age, and individual eye anatomy can influence how your eyes respond to pressure. Since you have a history of high myopia, it is crucial to keep an eye on these readings, as elevated eye pressure can be a risk factor for glaucoma, especially in individuals with myopia. Regular monitoring is essential, and if you notice any symptoms such as eye pain, headaches, or changes in vision, you should seek immediate medical attention.

In summary, while a 100-degree increase in prescription in a short time can be alarming, it may be influenced by lifestyle factors such as lack of sleep and eye strain. Your eye pressure readings are slightly elevated but still within a generally acceptable range. It is advisable to maintain regular check-ups with your eye care provider to monitor both your vision and eye pressure, especially given your high myopia. If you experience any new symptoms or changes in your vision, do not hesitate to reach out to your eye doctor for further evaluation. Taking proactive steps in eye care can help prevent potential complications in the future.
