------------------------------------------------ One eye has vision ranging from 20/20 to 20/40, while the other eye has vision ranging from 20/50 to blindness (with glasses).

Visual acuity is a measure of how well a person can see objects at a certain distance. The numbers 20/20, 20/40, and 20/50 indicate the distance at which the person can see compared to someone with normal vision. In this case, one eye has better vision, while the other eye has limited vision with glasses.

Explanation:

20/20, 20/40, and 20/50 refer to the visual acuity of an individual's eyes. Visual acuity is a measure of how well a person can see objects at a certain distance. In this case, 20/20 means that the person can see at 20 feet what a person with normal vision can see at 20 feet. 20/40 means the person can see at 20 feet what a person with normal vision can see at 40 feet. Finally, 20/50 means the person can see at 20 feet what a person with normal vision can see at 50 feet. So, one eye is able to see at a slightly further distance compared to the other eye, and the second eye has limited vision with glasses.
