This one, unlike most on the market, is actually of a decent length, long enough for those of us training our eyes to see at mid-distance. One word of caution: don't be tempted to remove or rearrange the balls, as it is almost impossible to thread them back on the string. Good value. Give it a try!

Myopia is the inability to see beyond a given (near) distance. This may help improve myopia, but is not the intention. I use it to improve my focus n the front sight of my air rifle. **Q: Will this exercise help achieve fusion if the eyes are slightly turned inwards, rather than outwards?** A: If you believe the research, based on how it works, all eye muscles should be strengthened. I bough it to help me to hopefully correct my blurred Red Dot. It took about 8 weeks before I noticed a change. Good Luck. **Q: How long do you needto do this to get results?** A: I really don't know. I've been doing it for a few months--a regular, brief daily routine--along with remembering to be aware of seeing out of both eyes, rather than ignoring my lazy eye. Don't know how long it will take to get results -- but I think of the words of my meditation teacher when asked a similar question: "try it for a couple of years and see what you think . . ." Good luck and if it's not helping, check out the book, 'Fixing My Gaze'. There's some good information in there. **Q: Does this fix eye asymmetry?** A: Hi, This product is intended for convergence training where the eyes work together to perform convergence at each bead. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A good length of string. *by S***O on 1 September 2025* Broc strings require patience and consistency of use.
