Should I see the Optometrist again (long details, sorry)?

I have always been on the borderline of needing glasses. I had them when I was 6 or 7 until I was about 12 when I ditched them for typical high school social reasons. They did not have an effect on my vision, and when I go for checkups they still tell me I can have glasses but don’t need them.

I went in May last year, because when I studied intensely I would notice a halo-type effect around the words/letters I was reading. The person I saw said that tinted glasses may help, because I am sensitive to light, and to come back in 6 months for progress. I returned in September because it was bothering me again, and saw a different optometrist who recommended eye drops, because the problem was a bad refractive index when my eyes dry out. These have helped a lot.

My issue is, during the May appointment the lady placed a lens over text while I was reading it, and I was able to concentrate better and read a lot faster. The man in September solved my original problem, but did not run this test so I am left wondering if I am reading and concentrating at my potential, and whether my natural laziness is due to this issue. I am not sure if it is a big deal and worth shelling out the money for glasses for such a benefit. Can you offer any advice on this?
