Amblyopia treatment does not happen overnight and requires a process. During this process, there is a possibility of a decrease in the effectiveness of the treatment. Many amblyopic children and their parents wonder about this. In fact, there is a big reason for this. 1. Inaccurate vision test results. Many amblyopic patients and their parents do not want to go to a regular hospital ophthalmology or optometry institution for cheap or convenience, and just find an optical store on the roadside and do a perfunctory job. The accuracy of the test results obtained in this way can hardly be guaranteed. In fact, a complete and accurate vision examination requires certain qualifications, equipment and professional staff. In this regard, the relevant laws and regulations in China have strict provisions. The average roadside opticians hardly have such strength. 2, lens damage. In amblyopia treatment, wearing glasses is the most basic treatment method. The lenses themselves have a certain service life, in addition to amblyopic children are generally younger, active and active, it is difficult to maintain the lenses as carefully as adults. Therefore, the lenses used by amblyopic children are more prone to scratches. Glasses are as therapeutic for amblyopia as medicine is for colds, and if the lenses are opaque due to wear or oil adhering to the lenses, it can affect the light entering the eyes and lead to a loss of vision with the lenses. If this situation is not brought to the attention of the parents, it is likely that the amblyopia treatment will be hindered by the impact on the light transmission of the lenses. 3. Poor patient compliance. Poor patient compliance is a problem that is often faced in amblyopia treatment. For example, some children may feel that the coverings are aesthetically displeasing and take them off secretly when their parents are not around. Other children may reject the idea of wearing glasses and often take them off and on. All of this can affect the effectiveness of amblyopia treatment. Therefore, children’s amblyopia treatment is inseparable from the supervision of parents. 4, not regular review. The most important role of amblyopia treatment is glasses, if a long time without review, glasses do not match the degree of the eye, not timely replacement of glasses, resulting in poor vision, or even wearing glasses is not as good as taking off the glasses vision, in the long run will certainly lead to a decline in the effectiveness of treatment.
