Is the depression film the same as the lens?

Wearing a pair of small glasses and a blue eye patch is a classic image of amblyopic children. It is inconvenient to wear a pair of glasses at an early age, and an eye patch really brings a lot of trouble to children. Many children refuse to wear eye masks or secretly take them off at school, which affects the effect of amblyopia treatment. In view of the fact that children can't insist on using eye masks, doctors use atropine mydriasis to suppress the vision of healthy eyes. The effect of this method on the vision of healthy eyes cannot be quantified. Atropine mydriasis will cause photophobia in healthy eyes and bring great discomfort to children.

Now you can choose a semi-permeable membrane called pressure sensitive membrane to stick on the lens, which can replace the ugly eye mask. This kind of laminating film has different densities, and it can reduce the quantitative vision to below 1.0 to 0. 1 when it is attached to the lens of normal eyes. Compared with the traditional covering method to treat amblyopia, pressing film has the following advantages. First, the appearance is beautiful. Fear of being laughed at by classmates with blindfolds is the main reason why children don't want to be blindfolded. With this translucent film, the appearance of glasses has hardly changed, but children can't see clear objects through the lens, thus achieving the purpose of covering. Second, the vision of healthy eyes can be quantitatively suppressed to one or two lines of sight lower than that of amblyopic eyes. When the healthy eyes are completely covered, although it can stimulate amblyopia eyes, it can not exercise children's binocular visual function. However, using the suppression film, healthy eyes and amblyopic eyes receive images of external objects at the same time during treatment. Although the image is not clear enough, it is of great significance to establish binocular simultaneous vision and stereoscopic vision. At the same time, it can also avoid blind amblyopia during treatment. Third, improve children's visual quality in the process of amblyopia treatment. If the healthy eyes are completely covered by the traditional eye patch, it is inconvenient for children with amblyopia to study and live, which is also an important reason for the failure of covering treatment. The use of suppression film can make healthy eyes see blurred objects at the same time, reducing the discomfort of simple covering. Moreover, with the continuous improvement of amblyopia vision, we can replace the suppression film with lower density to improve the visual quality of children.

Inhibition film is a more scientific method to treat amblyopia. It is suitable for monocular moderate amblyopia with visual acuity above 0.3, which not only significantly improves the visual acuity of amblyopia eyes, but also effectively protects the binocular visual function of children. At present, it has achieved good therapeutic effect in clinical application.
