I recently started wearing glasses at night due to my Astigmatism, I have 20/20 vision with a clarity of 6/6 so the DVLA are happy for me to drive without specs. So I don’t need glasses as such but they do improve my night vision. With a prescription 0.75 in each lens for distance i didn’t get them from the optician’s they wanted 200 squid, I purchased a vintage pair of titanium seiko glasses from early 80’s and had them reglazed so under 80 quid all in. I also purchased a test pair for £12 from one of them super cheap online prescription glasses maker to make sure they made any difference
