Many ophthalmologists are familiar with the concept of patching a child’s eye to treat amblyopia by forcing the brain to use the weaker eye. Some may even have experienced patching themselves. But this kind of treatment means that the dominant eye remains unused and the two eyes don’t work together. Researchers are now looking into more modern ways of treating the condition, including video games (1) – and now, a special type of movie.
Dichoptic therapy uses both eyes at the same time. In the case of the movies, viewers wear special glasses that partially block the images presented to each eye, so that one eye “fills in the blanks” for the other.
