An optometrist recommended corrective lenses for me as well to deal with slight astigmatism, and I gave it a shot for about 10 weeks before stopping it because it just never got comfortable. I've noticed that frequently putting them on/off causes a hint of a lingering headache, but I'm guessing that could be due to my eyes/brain trying to re-focus constantly.
These days, I've just made font sizes larger in the primary programs I use â" Terminal, IDE, mail, web browser, etc. That's made things much easier to read by taking much less effort. I've made a similar change on my mobile devices (laptop, phone). I figure every bit helps in reducing/slowing down the degradation of vision.
