Feeling Odd with New Glasses: Is It Normal or Time for an Eye Check? - Ophthalmology

When you get a new pair of glasses, it's not uncommon to experience some odd sensations or visual distortions, especially if there have been changes in your prescription or the type of lenses used. Based on your description, it sounds like you are experiencing a few different issues, including a sense of distortion and possibly an incorrect fitting of the glasses.
Firstly, the feeling that the floor appears to slope upwards or that objects look smaller can be attributed to a few factors. One possibility is that the optical center of the lenses is not aligned properly with your pupils. This misalignment can lead to visual distortions, making it difficult for your brain to process what you're seeing clearly. If the lenses are too far apart or too close together, it can create a sensation of seeing the frame of the glasses in your peripheral vision, which can be distracting and uncomfortable.

Another factor to consider is the type of lenses you have. If you have progressive lenses or bifocals, the transition zones between different prescriptions can sometimes cause visual distortions, especially if you are not used to wearing them. This can lead to feelings of dizziness or discomfort as your eyes and brain adjust to the new visual input.
Additionally, if your new glasses have a different curvature or thickness compared to your old pair, this can also affect how you perceive your surroundings. Thicker lenses can sometimes create a "fishbowl" effect, where peripheral vision is distorted, leading to feelings of unease or odd visual perceptions.

It's also important to consider the adjustment period. When you first start wearing new glasses, especially if there has been a significant change in prescription, it can take time for your eyes and brain to adapt. This adjustment period can last anywhere from a few days to a couple of weeks. During this time, you may experience some discomfort, including headaches or a feeling of pressure around the eyes.

However, if these sensations persist beyond a week or two, or if they worsen, it is advisable to return to the optician or eye care professional for a follow-up examination. They can check the fit of the glasses, ensure that the prescription is correct, and make any necessary adjustments. It’s crucial to address these issues early on, as prolonged discomfort can lead to eye strain or other complications.

In summary, while some odd feelings with new glasses can be normal, especially during the adjustment period, it’s essential to monitor your symptoms. If you continue to feel discomfort, or if your vision does not improve, seeking professional advice is the best course of action. Your eye health is paramount, and ensuring that your glasses fit correctly and provide the right prescription is crucial for maintaining clear and comfortable vision.
