Vision Convergence Training Tool, 6Ft with 5 Beads, Pack of 3

This string provides a means to work on convergence problems. I have excellent vision in my eyes but when I'm tired etc. I start seeing double --especially watching the television. I can see improvement after just a few sessions of the exercises. Hopefully before long I will no longer have the problem. Comes with instructions in English! They just don't indicate how long one should do them. If you get one, practice at least a few minutes at a time.

It does exactly what it is supposed to do. It is of good quality and has been helpful.

Muy útil!

Effectively fulfills its function. Some of the beads are looser than others and their position needs to be corrected with each use. I would recommend this product.

The product was just like the description. I felt the paper on how to use this product. Was a little difficult to understand for me.0

One of the most important results I get from using this product is the tracking of both my eyes at the same time. It helps develop and improve my comprehension when studying and reading because both my eyes are now tracking at the same time which allows the information to flow to me without blockage. This product is now hanging from a wall in my office, and I use it every day for a couple of minutes to ensure my mind is opened to learning! Highly recommend!

This Brock string is much better quality than I expected. It's not medical grade, but the balls don't easily slide around when you're using it; they stay in place. But they are also easily adjustable for multiple exercises. The string is kind of a plastic string material, so it can stay pretty taut, which is necessary for the eye exercises it's used for. It's easy to tie and untie. I just tie it to a cabinet handle, and it works great!

Had a Brock String for one of my children some years ago. The beads were much larger than on this product, and therefore, easier to see. That can be important for someone trying to work on vision problems. The third bead out in the standard 3-bead set up is light green, which adds to the difficulty of being able to see it. Had to order larger replacement beads. Also note, the beads are not anchored in place with knots. You have to read the instructions, get out a ruler, and tie the beads n place yourself.

It arrived in a good condition, both the bead and the string are of good quality. The bead also doesn't shift easily so it is great!

Bom

Funciona bien.

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!
