The patients which are of high prescriptions over +/- 4.00, might need to get the BVD (Back Vertex Distance).
The cylinder value is linked to astigmatism and helps in knowing about the curvature deviation of the eyeball. Through Cyl, it helps in telling the precise changes which will help you see clearly.
