You hold one end of the string at your nose while the other end is fixed to a wall or anchor point. By focusing on each bead along the string, you practice visual convergence — the ability of both eyes to work together to focus on a single point. The five colored beads on this set allow for progressive training at different distances.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this Brock String at home without professional guidance?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! This tool is designed for easy home use with a very short learning curve. Simply attach one end of the string to a fixed point at eye level, hold the other end lightly to the tip of your nose, and focus on each bead one at a time. Many users are able to start their eye coordination training sessions right away.\u003c\/p\u003e\n\u003ch4\u003eQ: Is the iron storage box included, and is the set portable?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. Every set includes a compact iron storage box measuring 11.4 × 8.3 cm (approx. 4.49 × 3.27 in), which keeps the string and beads dust-free and neatly stored. Its compact size makes it easy to toss in a gym bag or backpack for training on the go.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is a Brock String and how does it work for eye training?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A Brock String is a classic visual training tool used by vision therapists and athletes alike.
