Put on your new glasses, go to the optical shop for a double check-up and look at astigmatism table with one eye. If you still feel that there is a particularly thin black line or solid line (if astigmatism table is a dotted line), it means that astigmatism has not been corrected.

In addition, it is necessary to confirm which eye is the main eye and whether the corrected vision of both eyes is the same or close. If the vision of the accessory eye is better than that of the main eye, it needs to be adjusted.

The astigmatism axis does not change much, so it will not have much influence. Moreover, it can be clearly said that the glasses three years ago were optometred according to the computer optometry instrument, and the astigmatism axis was not fine-tuned at all.
