## Questions & Answers

**Q: Will this improve bad case of myopia in adolescent?**
A: This device improves depth perception, the ability of both eyes to focus at the same distance.  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. 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!
