Took a little longer to get to this than I'd hoped, but my eye doctor gave me a free sample of Vuity eye drops. These are a slightly different product than the Vizz drops I wanted, but I gave them a try today anyway.
I put one drop in each eye and within about 10 minutes they were a little red and I started to get a mild headache.
After another 20 minutes the redness was gone, and the headache was lessening. By 45 minutes the headache was gone.
It's a little hard to put visuals into words, but I'll try.
There was a definite improvement in what I could see or read within about 36 inches. Beyond that I can't say there was a difference.
As an example, I could easily read the ingredients on the back of an energy drink, or all the text on my driver's license, but still can't read anything smaller than that. I should note that I normally cannot read either of those without my glasses.
I also noticed that the room seemed dim. I'd say it's comparable to wearing light tinted sunglasses indoors. Not really an issue, but I'm not sure I'd want to drive at night like this.
As far as shooting pool, the benefits were small. As I mentioned it seems the vision improvement was all within three feet, so beyond that no real change. I did find it easier to see the gaps when racking the balls and making sure I had full chalk coverage on my jump cue, but as far as general shot making, I didn't think it was any better or worse. I was also able to see/use the CompuSport and Fargo apps on my phone.
I may try them again over the next few days just to see if my results change at all from repeated use, but after one try, I'm not totally sold on it.
I would still like to try the Vizz brand just because they claim they have fewer side effects and last longer, which might give it more value, but it would likely be just for convenience of reading things etc and not really for pool.
