The new lenses are too bright and dazzling?
Hello, I have myopia of -500 and astigmatism of -200.
Recently, I got a new pair of glasses (the frame was not changed).
My old glasses had spherical lenses, while the new ones have aspheric lenses.
The new glasses have an increase of 25 and 50 degrees in astigmatism, but the myopia degree has not increased.
However, when wearing the new lenses, I find them extremely bright and glaring, especially at night when traffic lights are blinding.
The optometrist only advised me to adapt to them.
What could be the reason for this, and what should I do?

Hello, it should be related to the difference in transmittance.
If you still cannot gradually adapt after a month, you should consider getting a replacement (currently, glasses come with a warranty period of 2 to 3 months, so remember to take advantage of it).

More Info
When you experience discomfort with your new glasses, particularly feeling that they are excessively bright or glare-inducing, there are several factors to consider. The transition from your old spherical lenses to new aspheric lenses can significantly affect your visual experience. Here’s a breakdown of why this might be happening and some suggestions on how to address it.
Understanding the Change in Lenses
1. Lens Design: Spherical lenses have a uniform curvature, which can provide a more consistent visual experience. Aspheric lenses, on the other hand, are designed to reduce distortion and provide a wider field of view, especially for higher prescriptions. However, this design can also lead to a different perception of brightness and glare, particularly if you are not accustomed to them.
2. Increased Astigmatism Correction: You mentioned that your astigmatism has increased by 25 and 50 degrees. This change can affect how light enters your eyes and is focused, potentially leading to increased sensitivity to light and glare. The brain may take time to adjust to the new way light is processed through these lenses.
3. Lens Coatings: If your new lenses have different coatings (e.g., anti-reflective coatings), this can also influence how light interacts with the lenses. Anti-reflective coatings can help reduce glare from lights, but if they are not present or not functioning well, you may experience more glare.
Why You Might Feel Discomfort
- Adaptation Period: It’s common to experience an adaptation period when switching to new lenses, especially if there are significant changes in prescription or lens type. Your eyes and brain need time to adjust to the new optics.
- Environmental Factors: The lighting conditions in your environment can also play a role. Bright lights, especially LED lights, can create a harsh glare that may feel more pronounced with new lenses.
- Eye Health: If you have underlying issues such as dry eyes or other ocular conditions, these can exacerbate sensitivity to light. It’s essential to ensure that your eyes are healthy and that any discomfort is not related to an eye condition.
What You Can Do
1. Give It Time: Allow yourself a few days to a couple of weeks to adjust to the new lenses. If the discomfort persists beyond this period, it may be worth revisiting your optometrist.
2. Check Your Fit: Ensure that your glasses fit properly. Misalignment can cause visual distortions and discomfort. The optical center of the lenses should align with your pupils.
3. Consider Lens Adjustments: If the brightness and glare remain bothersome, discuss with your optometrist the possibility of adjusting the prescription or exploring different lens options, such as lenses with a different coating or even a different design.
4. Use Anti-Glare Solutions: If glare from lights is a significant issue, consider using anti-glare glasses or lens coatings that can help mitigate this problem.
5. Monitor Your Eye Health: If you experience ongoing discomfort, including headaches or visual disturbances, it’s crucial to have a comprehensive eye exam to rule out any underlying conditions.
6. Environmental Adjustments: When possible, adjust your environment to reduce glare. For instance, using softer lighting or avoiding direct bright lights can help ease discomfort.
Conclusion
Feeling that your new glasses are excessively bright and glare-inducing can be attributed to several factors, including the transition to aspheric lenses, increased astigmatism correction, and potential environmental influences. While some discomfort is normal during the adjustment period, persistent issues should be addressed with your eye care professional. They can provide tailored solutions to ensure that your vision is comfortable and clear. Remember, your eye health is paramount, and any ongoing issues should not be overlooked.
