WebGeneral expression for the aberration coefficient of spherical aberration of a spherical thin lens is: with n being the refractive index, q= (R2+R1)/ (R2-R1) the lens shape factor, and p=1-2f/I the lens position factor ( f is the lens focal length, and I the image-to-lens separation). For object at infinity, f=I and p=-1, and. WebAs at Visit 1, spherical over-refractions were performed with spherical contact lenses to ensure the optimal spherical equivalent was used for visual acuity testing, and spherocylindrical over-refractions were performed with toric contact lenses to correct any residual lower-order aberrations that remained, leaving only higher-order aberrations ...
