Final answer:
Esophoria is a condition causing inward eye deviation. Prisms with base-out orientation can help correct the misalignment of eyes in esophoria.
Step-by-step explanation:
Esophoria is a condition that occurs when the eyes tend to turn inward, causing a person to have difficulty keeping their eyes aligned properly. In such cases, the use of prisms can be helpful.
Prisms can be used to adjust the direction of light rays entering the eyes, helping to correct the misalignment and improve binocular vision. In cases of esophoria, prisms with base-out orientation are commonly used.
These prisms refract (bend) light towards the outside, which helps to shift the perceived image slightly outward. This can mitigate the inward deviation of the eyes caused by esophoria.
