Vision training, also known as visual training or vision therapy, refers to a collection of techniques and exercises designed to improve and enhance visual skills and abilities. It aims to develop and strengthen the coordination between the eyes and the brain, as well as improve visual perception, visual processing, and eye movement control.

Vision training is typically conducted under the guidance of optometrists, ophthalmologists, or vision therapists who specialize in diagnosing and treating various visual problems and conditions. These professionals assess and address issues related to visual acuity, eye teaming, eye tracking, depth perception, visual memory, visual motor integration, and other aspects of visual function.

The specific techniques and exercises used in vision training can vary depending on the individual's needs and goals. They may involve activities such as eye exercises, focusing exercises, eye-hand coordination tasks, visual puzzles, computer-based training programs, and specialized equipment like prisms, lenses, or filters.

Vision training is often prescribed for individuals with various visual conditions or deficiencies, including:

1. Amblyopia (lazy eye): Vision training can help improve the coordination and functioning of the lazy eye.
2. Strabismus (crossed or misaligned eyes): Exercises can help align the eyes and improve binocular vision.
3. Convergence insufficiency: Training can improve the ability to focus the eyes together, particularly for near tasks.
4. Visual processing disorders: Techniques are employed to enhance visual processing skills, such as visual discrimination, sequencing, and tracking.
5. Sports vision enhancement: Athletes may undergo vision training to improve hand-eye coordination, depth perception, and peripheral vision.

Vision training is a gradual process that requires regular practice and commitment. The duration and frequency of the training sessions depend on the individual's needs and progress. It is important to note that vision training should be conducted under the supervision of a qualified eye care professional to ensure proper assessment, personalized treatment plans, and monitoring of progress.
