When it comes to understanding prescription changes and the safety of new glasses, it's important to consider several factors that can affect your vision and overall eye health. Based on your description, you have been wearing glasses for four years, and your prescription has changed from -2.25 to -3.00 diopters. You are experiencing discomfort, including feelings of dizziness and nausea, after getting your new glasses.
Firstly, it’s essential to recognize that a change in prescription is quite common, especially for individuals with myopia (nearsightedness). As the eye grows and changes over time, the degree of myopia can increase, necessitating a stronger prescription. However, the transition to a new prescription can sometimes lead to discomfort, particularly if the new lenses are not properly aligned or if there is a significant change in the prescription.

Here are some potential reasons for the discomfort you are experiencing:
1. Adjustment Period: When you switch to a new prescription, your eyes may need time to adjust. This adjustment period can last from a few days to a couple of weeks. During this time, you might experience symptoms like dizziness, nausea, or even headaches. If these symptoms persist beyond a couple of weeks, it may indicate that something is wrong with the prescription or the fit of the glasses.

2. Lens Type and Design: Different lens designs (single vision, bifocal, progressive) can affect how you perceive your surroundings. If your new glasses have a different lens design than your previous ones, it could contribute to discomfort. Additionally, if the lenses are not properly centered in front of your pupils, it can lead to visual distortions.

3. Incorrect Prescription: Although you mentioned that the prescription is the same (-3.00), it’s possible that there was an error in the lens manufacturing process or in the way the prescription was interpreted. It’s always a good idea to double-check the prescription with your eye care provider to ensure accuracy.

4. Visual Fatigue: If you spend a lot of time on screens or reading, your eyes may become fatigued, especially with a new prescription. This can exacerbate feelings of discomfort. Make sure to take regular breaks using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds.

5. Underlying Eye Conditions: If you have a history of eye conditions, such as retinal issues or glaucoma, it’s crucial to monitor any changes in your vision closely. Sometimes, discomfort can be a sign of an underlying issue that needs to be addressed.

To address your concerns about whether wearing these new glasses is harmful to your eyes, here are some recommendations:
- Consult Your Eye Care Provider: If the discomfort continues, make an appointment with your eye care provider. They can assess the fit of your glasses, check the prescription, and ensure that there are no underlying issues affecting your vision.

- Give It Time: If the glasses are new, allow yourself a reasonable adjustment period. However, if symptoms persist beyond two weeks, seek professional advice.

- Consider Lens Options: If you find that the current lenses are not suitable, discuss alternative lens options with your eye care provider. There may be different materials or designs that could alleviate discomfort.

- Practice Good Eye Care: Maintain regular eye exams, practice good eye hygiene, and manage screen time to reduce eye strain.
In conclusion, while a new prescription can sometimes lead to temporary discomfort, it’s crucial to monitor your symptoms and consult with your eye care provider if they persist. Your eye health is paramount, and ensuring that your prescription is accurate and comfortable is essential for maintaining good vision.
