We encounter many children in our clinic who have very different corrected visual acuity in both eyes and very severe amblyopia in one eye. The traditional treatment for this type of amblyopia is to use an eye patch to cover the good eye and exercise the eye with poor vision. However, this method is very difficult for older children, especially those who go to kindergarten or school, because in kindergarten and school children already have their own social activities, and wearing a large and thick eye patch is often laughed at by other children and affects the child’s psychological development, and many children immediately remove the eye patch as soon as they arrive at kindergarten or school, which seriously affects the This seriously affects the effect of amblyopia treatment. Moreover, the use of eye shields completely covers the good eye, so the child usually sees with only one eye, and there is no stereopsis in one eye. This is not conducive to the development of stereopsis in amblyopic children on the one hand, and on the other hand, life is not convenient, especially when walking and climbing stairs is not safe enough. Foreign studies have also shown that the effect of using both eyes together for amblyopia treatment is far better than using one eye. Therefore, for such babies, we can use a special suppression film. This suppression film is designed with different levels of 1.0 0.9 0.8 0.6 0.4 0.3 0.2 0.1 light sensitivity, which can be individualized to the child’s vision and can be changed as the child’s vision improves. The application of this technology not only discards the disadvantages of traditional eye shields that affect the appearance and increase compliance with treatment, but also makes training more personalized and can be adjusted accordingly with the treatment process.
