Prescription Eyeglass
What does sphere and cyl mean on my eyeglass prescription?
sphere Cyl
OD -0.75 DS
OS -0.75 DS
This is how the prescription reads.I wonder if it is only a reading glass strength.
sphere cylinder axis
A spherical correction corrects refractive error of the eye with a single convergent or divergent refractive power in all meridians.
A cylindrical correction corrects astigmatic refractive error of the eye by adding or subtracting power cylindrically in a meridian specified by the prescribed axis.
The Axis indicates the angle in degrees of one of two major meridians the prescribed cylindrical power is in. Which major meridian is referenced is indicated by the cylindrical correction being in plus or minus notation. The axis is measured on an imaginary semicircle with a horizontal baseline that starts with zero degrees in the 3 o’clock (or east) direction, and increases to 180 degrees in a counter-clockwise direction.
