Here are my findings:
1) Day 1 and 2 I used the drops about 30 minutes before my dive op picked me up. I never noticed the “ache” in my eyes noted in post #5. Just too much going on right before you start diving. I did notice the drops made my far off vision just a little funky. Some random “interference” looking areas. My close up vision was definitely better than without the drops. Both of these days were full sun.
2) Days 3 and 4 were both overcast and so I did not use the drops. I did not want to make the dive seem darker, which the drops will do. My dive computer on days 3 and 4 was just a little unclear, as you would expect with my slight farsightedness. Day 5 will also be overcast, so I do not think I’ll use the drops.
Essentially, as noted by mbs above, I don’t really need the drops to read my computer. They do make it easier. However, as my eyesight degrades over time (and we all know it will), I do think I’ll try using them before I start with the magnifiers in the mask.
