How to enter option box --Understanding Your Prescription

OD (oculus dextrum) indicates that the readings are for your right eye.

OS (oculus sinistrum) refers to your left eye.

The SPH (Sphere) box shows a measurement of how long sighted (hyperopic) or short sighted (myopic) you are.

If you are short sighted, the SPH value will have a minus (-) sign before it.

If you are long sighted, the SPH value will have a plus (+) sign before it.

diplopia


The (D) stands for dioptres which is the standard measurement that is used. If the SPH value is between 0 and 3.0D then you have a mild prescription. 3.0 to 6.0D is moderate and 6.0D and above is a high prescription.

line


The CYL (Cylinder) box shows the strength of any astigmatism.

An eye with astigmatism will not be perfectly spherical and will be like a rugby ball in shape. Astigmatism can be plus (+) or minus (-) and is also measured in dioptres.

If one of your eyesight is Myopia -2.50, please select 0 for CYL and AXIS.

line


The AXIS box shows the orientation of the cylinder (from 0-180 degrees).

If you can not find your AXIS in the Options box, Please round off to the nearest integer in AXIS. EX) AXIS is 153 >> Select 150

Since glasses are away from the eyes are contact lenses are attached to the eyes, there's a difference in the vertex distance. I recommend you to check your vision of your lenses precisely.
