As we all know people who wear glasses will use their hands to push glasses to adjust their own line of sight in order to see things better.Because the general spectacle lenses has a degree only in the middle place,once the stabismus,beyond the scope of degree we will not see,at the same time as the result of the frame block,large angle of view is often very vague.
Bubble glasses solves this problem.The glasses ,such as a container,store inside the liquid.At the same time,there is a bubble.This bubble is equivalent to the usual spectecle lens and it has a degree.Eyes through the bubble can clearly see objects.
