Question

If one eye is set closer to a person's nose than is the other and the optical centers of the lenses are placed symmetrically in the frames, the wearer's lines of sight will not pass through the optical centers of the lenses. The error is not too serious if the lenses are of the _________ power and are ______ strong.

Answer 1

The error in vision when one eye is set closer to a person's nose than the other can be corrected with converging (convex) lenses, which are prescription glasses for farsighted people.

Step-by-step explanation:

When one eye is set
closer to a person's nose than the other, it results in a condition known as
asymmetrical convergence. This means that the lines of sight from the two
eyes do not pass through the optical centers of the lenses, resulting in an
error in vision.

To correct this error, the lenses need to be of
converging (convex) power. These lenses are also referred to as
prescription glasses for farsighted people. The lenses are designed to
converge the rays from close objects onto the retina, allowing the person to
see objects at close range clearly.
