The power of the same lens cannot be modified twice.

Because the power of the lens is fixed, the lens is disposable. After being cut and polished according to the power, interpupillary distance, and frame, it cannot be reused on other frames. Currently, there is no method to make adjustments.

If the power of your new eyes is not suitable, you can negotiate with the store to find the best solution and see if you can replace them with new lenses. If not, you will have to undergo an optometry test again.

When wearing glasses, there will be tested lenses for customers to wear and adapt to for a period of time. During this process, the power, interpupillary distance and other data can be modified and corrected according to their own experience. .

Extended information:

Under normal circumstances, there will not be much deviation after the glasses are fitted. If you feel there is something wrong with the prescription, you basically need to re-optometrically and re-fit glasses based on the newly measured prescription and other information.

When getting glasses, it is best to go to a professional hospital or optical center, so that the refraction will be more accurate, there will be no obvious deviations, and the comfort after wearing the glasses can be guaranteed. Moreover, these institutions are highly professional and have better after-sales services. If you encounter problems with wearing discomfort, you can communicate better and avoid unnecessary troubles.
