Transpose the following into a minus cylinder: +3.00+1.00x180.

To transpose a prescription from plus cylinder to minus cylinder, you need to follow a specific process.

Starting with the given prescription of +3.00 +1.00 x 180, the first step is to recognize that the ‘+1.00’ represents the power of the cylinder, and '180' is the axis of that cylinder. To transpose this into a minus cylinder, you essentially switch the signs of the cylinder power and adjust the sphere power accordingly.

1. Keep the sphere power: The sphere (+3.00) remains as the base value.

2. Adjust the cylinder power: The cylinder power (+1.00) becomes -1.00 in minus cylinder form.

3. Change the axis: The axis of the minus cylinder is adjusted by 90 degrees. Since the original axis is at 180 degrees, the new axis will be at 90 degrees.

By applying these steps, you will arrive at a new prescription in minus cylinder form:

• Sphere: +3.00 stays the same.

• Cylinder: The power is now -1.00.

• Axis: The axis is adjusted to 90 degrees.

Putting this all together results in: +3.00 - 1.00 x 90,
