What is the spherical equivalent of +2.00 +5.00 X 180?

• A. +5.00
• B. +4.50
• C. +7.00
• D. +3.50

Answer: (B)

To determine the spherical equivalent of a prescription given in cylindrical form, such as +2.00 +5.00 X 180, the process involves converting the cylindrical component to its spherical equivalent. The formula for calculating the spherical equivalent is: Spherical Equivalent = Sphere + (Cylinder/2) Here, the sphere is +2.00 and the cylinder is +5.00. Calculating the spherical equivalent: 1. Start with the sphere: +2.00 2. Divide the cylinder by 2: +5.00 / 2 = +2.50 3. Add this value to the sphere: +2.00 + +2.50 = +4.50 Thus, the spherical equivalent of +2.00 +5.00 X 180 is +4.50. This makes the second option the correct choice, as it accurately reflects the conversion process for obtaining the spherical equivalent. The other options either represent values that do not follow the spherical equivalent formula or do not accurately result from the calculations involving the provided prescription values.

To determine the spherical equivalent of a prescription given in cylindrical form, such as +2.00 +5.00 X 180, the process involves converting the cylindrical component to its spherical equivalent.

The formula for calculating the spherical equivalent is:

Spherical Equivalent = Sphere + (Cylinder/2)

Here, the sphere is +2.00 and the cylinder is +5.00.

Calculating the spherical equivalent:

1. Start with the sphere: +2.00

2. Divide the cylinder by 2: +5.00 / 2 = +2.50

3. Add this value to the sphere: +2.00 + +2.50 = +4.50

Thus, the spherical equivalent of +2.00 +5.00 X 180 is +4.50. This makes the second option the correct choice, as it accurately reflects the conversion process for obtaining the spherical equivalent.

The other options either represent values that do not follow the spherical equivalent formula or do not accurately result from the calculations involving the provided prescription values.
