i use glasses that are a 1.5 (plus or minus?) for looking at things more than 10ft away, but usually only need them for reading signs or driving, otherwise im a little blurry but 99% managable.
fractals dont seem affected, but visuals like grass moving or forming patterns are focused because the grass is in focus.
blurry vision isn't particularly psychadelic, it just adds to confusion, even when you're not tripping. I always wear glasses or contacts, whether I'm tripping or not.
blurry isnt the right term per se. i am competent without glasses, but if im driving its the difference between staring at a license plate 30ft ahead for 5seconds and reading 2-3 digits vs reading the entire plate in a quick glance.
im glad i dont need to wear anything (at least not yet), but i think id wear my glasses. contacts just freak me out for some odd reason. eyeball touching, eww
I have terrible vision (I can't even see the giant "E" at the top of the eye chart without my glasses), and yet my CEVs are always crystal-clear and sharply in focus. On the other hand, I don't tend to be all that interested in the visuals anyway. I don't know if that's connected with my bad vision or not, I never really thought about it before.
Aldous Huxley also had terrible eyesight, and he said in the Doors of Perception that he found no interest in the CEVs from mescaline, but he did enjoy the OEVs.
kingme, touching your eyeball isn't *that* big of deal, you could get used to it if you needed to.
I have better than perfect vision but my girlfriend wears glasses or contacts all the time. She's told me she prefers contacts for psychedelics, because of the area outside the lenses, of her glasses, stays blurry.
I have seen her remove her glasses during a mushroom trip for about half the time. Never asked why though.
