Does your licence demand that you wear glasses?
In that case, you have to show that your eye sight meets the minimum standard even uncorrected.
This affects a lot of people who have had laser eye surgery. Their licence contains the code and they haven’t updated because of the cost but their eyesight is adequate.
To do that though you would need an optician’s report and to go to court. They won’t drop this unless, of course, the optician’s report is overwhelming.
Can I clarify anything for you?
It would have to say categorically that your eyesight was diagnosed at X level and that level would need to be higher than the minimum the DVLA demand.
That is not usually too difficult. Opticians don't sit on the fence generally.
All the best.
