Will this improve bad case of myopia in adolescent?

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.

Will this exercise help achieve fusion if the eyes are slightly turned inwards, rather than outwards?

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.

How long do you needto do this to get results?

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.

Does this fix eye asymmetry?

Hi, This product is intended for convergence training where the eyes work together to perform convergence at each bead.

S**O

A good length of string.

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!

Troppo caro per un cordino e 5 pallini di plastica colorata

È utile ma vale un decimo del prezzo che l'ho pagata. Potete farvela da soli

Overpriced for a string & 5 beads

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

Well-Made Training Tool

The 10 ft Brock String is sturdy and comes in a slim metal box. The build quality is great, but the instructions were only in Chinese—so I recommend watching a video to learn proper use. I’m using it for diplopia exercises, and it works well.

Bien pero...

Lo usé pero es el típico artículo que usas dos días y después te aburre . O estás muy concienciado o es un desperdicio de dinero.
