Lens Complexity
A simple pair of glasses has spherical lenses of similar power. If one eye is weaker than the other, or you have astigmatism, lenses to compensate for that are more complex. The reduced lens method recommends that you start with small and even spherical reductions first, then after you've accomplished a few of those, then work on reducing complexity.[2][3] Guide:Reducing lens complexity
Components
There are three major components in your lens complexity.[2]
Dipoter Ratio
The difference between your left eye and right eye spherical correction. The reduced lens method recommends that you start reducing the dipter ratio only you have done with astigmatism.[2]
Astigmatism Correction
You may reduce your close-up astigmatism correction first, then work on reducing your astigmatism for distance.
Astigmatism Correction Difference
The difference between your left eye and right eye cylinder correction.
