Balance Glasses Prescription

What does balance in eye perception mean? 3

Here is my prescription:

Right eye 4.25 +150 axis 115

Left eye balance (I think it says)

This means that no prescription can be used for this spectacle because the vision of this eye is impaired, such as poor eyesight or overall in this eye. A lens is inserted into your eye to balance your eyesight so that it does not look bad. For example, Libra as your left eye, I assume you have little or no vision in that eye. So since you have a lot of vision in your right eye and for that eye your lens will be thick enough to replace the lens, the same lens will be applied to the other eye so that your lens is not visible through the thick and thin lens. ۔ .
