The value written right after the sphere one in a prescription is your astigmatism prescription. When the value in the column is equal to zero, either you have no astigmatism, or the power of astigmatism happens to be so small that it does not need correcting with eyeglasses or lenses.

But when the value in the column precedes a minus sign, then you have nearsighted astigmatism. Also, when the power has a plus sign, you have farsighted astigmatism.

The Axis value will range between 1° to 180°, which is extremely useful in rectifying astigmatism. However, to reduce mistakes, the doctors write the axis value as three digits. For example, an axis quantity of 65 is 065.

Furthermore, when an eyeglass prescription comprises cylinder power, it also includes the value of the axis. Contrarily, when it does not have any cylinder power, then there will be no axis value.

Note: When doctors write freehandedly, the axis figure comes after an X sign.

ADD gives patients a positive vision at a considerable range for near-point and reading activities. Generally, this value is nonexistent in adolescent eyeglass prescriptions. Yet, some adolescents still can develop near-focusing issues and may need an ADD power.
