## 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

### ⭐⭐⭐⭐⭐ 







  
  
    Very helpful.
  

*by P***K on Reviewed in Canada on 5 October 2024*

Honestly, it's amazing as a cheap eye convergence device. helps me a lot with my problems. Deep down I feel really petty about wanting to complain about how my mom when I was younger refused to get me one of these. Like dude, they're so cheap too. It trains the part of your brain that moves the muscles very well.

### ⭐⭐⭐⭐⭐ 







  
  
    Great concussion tool
  

*by S***I on Reviewed in the United States on 27 September 2024*

Instructions Have colors of beads in a specific order that doesn’t match the actual string order. I tried to remove and replace beads but had a hard time stringing them. So purchased another also stringed incorrectly. Not sure color order makes a difference but I thought the tool was still effective.

### ⭐ 







  
  
    Overpriced for a string & 5 beads
  

*by B***R on Reviewed in Singapore on 10 February 2024*

Beads unfixed. No loop for fixing or holder. Just a piece of string and 5 beads. Disappointing.
