Convert Eyeglass Prescription to Reading Glasses:How To

Sphere power is the main strength of your eyeglass prescription, and it is written in increments of 0.25. The add stands for the additional correction that is used for reading glasses. Essentially, the formula for converting an eyeglass prescription to reading glasses is adding your sphere power to your add power.

Difference in Prescription

+0.75 sph and -0.50 Cyl 180 degrees. If I convert this in +cylinder, it will be:+0.25 sph and +0.50 Cyl 90 degrees. These two are the same. So if you look to your new prescription (also written with +cylinder) you will see that the differences are small. Same with the left eye:Old:+2.00 sph and -0.50 Cyl 180 degrees is EyeWorld Understanding spherical aberrationThe average spherical aberration of the anterior cornea surface is slightly positive (between +0.27 and +0.30 m), remaining stable throughout life. 2 The natural crystalline compensates for this positive spherical aberration, inducing a negative spherical aberration of 0.20 m, leaving a slightly positive total aberration of +0.10 m. Spherical aberration of the lens changes over time unlike spherical aberration
