Ted, I need reading glasses to read, but have over the years realized I will NEVER remember to bring the stupid things with me to the hives, and so as events progress, I never had them with me when I needed to see eggs... I have learned through persistence, the right distance to hold the frame, and the correct angle to hold the frames to get the sunlight into the bottom of the cells, and CAN usually spot eggs, but thats not how it started. Took me a good while and lots of swearing, walking back to get the glasses etc...
Now, i also realize you wear glasses, so wearing two pair would be bothersome... So I considered options.... A magnifying glass means you have to have one hand to hold that magnifying glass, so maybe a small table/cart with a mounted/lighted magnifying glass you can stick the frame under? I had one I used to make small parts when i was a gunsmith.. LOVED that thing... Other option is bifocals and a hat with a light on it? WHITE LED makes the eggs more visible to me, they almost glow... I just... CANT... remember to bring it with me....
You have seen/used the magnifiers I use to punch cells with, they work very well too... so long as... yeah, I remember to bring them.....
