Many children who do not learn well and are labeled by teachers or parents as bored with school, lazy, ADHD, etc., are in fact mostly just suffering from a visual impairment. Once this visual impairment is lifted, the child’s academic life can be turned upside down. According to U.S. data, its cure rate is 90 percent. Unfortunately, this disorder is very subtle and not easily detected. Most children, until they drop out of school, do not know the original cause. 1. Most learning is done visually According to statistics, 80% of people’s information acquisition is done visually, and this is especially true for students. Reading, spelling, writing, copying, slating, looking at the computer, and other common ways students learn, are all related to their visual abilities! Like a scanner, the performance of a child’s eye to quickly scan, visually distinguish, transmit, integrate, and understand information determines the quality and speed with which it can do this work. Many students’ visual ability happens to fall short of learning requirements, thus seriously affecting academic performance, and can even cause children to give up on themselves as a result, seriously affecting their healthy growth. 2.What are the visual abilities that are related to learning? Vision is a concept greater than visual acuity. A child with 1.0 or even 1.5 vision is not necessarily a good vision. The 1.0 visual acuity we are talking about is a measure of the eye’s ability to see small objects – visual acuity – but this ability is not the same thing as the ability to learn through reading. The visual abilities that affect learning include not only clear vision, but also binocular coordination, hand-eye coordination, visual perception, visual memory, visual imagination, sweeping vision, gaze, and reading comprehension (I will cover each of these abilities in a future article). If these abilities are not developed or are poorly developed, learning will become very difficult. 3.What are the signs of visual impairment? According to the latest data from the United States, about 1/4 of children and 7/10 of troubled adolescents suffer from visual impairment that affects learning. Visual impairment usually has the following manifestations: avoid close eye work, as little as possible; take a long time to do homework, far beyond the requirements of the topic; do homework scribble, sloppy, tired to cope; often uncomfortable, fatigue, inattention; appear myopia or monocular inhibition; learning completely unable to keep up with the progress; timid and isolated, not confident. 4.How to solve visual impairment after it appears? These learning-related visual impairments (also known as visual disabilities) can be quickly and completely cured when detected in time, however, the treatment methods are completely different from the traditional methods of medication, injections and surgery. One type of approach is to use progressive multifocal lenses, bifocals or prisms to solve visual problems, but such specially customized glasses are generally based on different purposes and have special methods of use, and must be used according to the requirements of specialists. For example, some glasses are for training and some are for weight reduction, and the usage of course varies for different purposes. Another type of method is visual training, through a series of complex and varied training activities, so that the child gradually builds up the visual ability to efficiently acquire and understand external visual information. Usually, these training activities are very diverse, varying from person to person, using different tools and methods, and are often adapted from time to time, often in a dizzying manner. While visual training and vision therapy has been a very mature profession in Europe and the United States for nearly 100 years, with some training methods already certified by the F-D-A, in our country this work is just beginning. In the Vision Therapy Clinic at SUNY Optometry, there are nearly 1,000 patients receiving vision consultations and vision training every month, most of whom are adolescents. 5. How can I detect my child’s vision problems early? Many children with vision problems have very normal vision. The traditional light box vision chart is unable to detect visual impairment, and many visual problems that affect learning are therefore ignored. If you want to check whether your child has visual problems that affect learning, you should always seek professional eye specialists and use professional equipment for examination. However, attentive parents or teachers can use the following clues to do a preliminary screening. If your child has one of the following manifestations, you should seek a visual examination by an eye specialist as soon as possible.
