Ps. Trivex Polycarbonate 1.60 index 1.67 index Human eye 59/59 56 45 30 42 32 45 Eyecare professionals have long sought to understand the exact nature of the vision-degrading effects of low Abbe value, and how they can calculate at what point Abbe will have a negative impact on a person’s acuity or contrast sensitivity. The majority of your Rx is your astigmatism which at axis ~180 means all the thickness will be vertical. The impact resistance of Trivex is comparable to Polycarbonate. Optical clarity (central). I assume you are getting lenses online or from a box/chain store who employ sales clerks and not opticians. However, unlike polycarbonate, Trivex has an Abbe value of 45, making it optically superior. Location 660 West Cherry Street North Liberty, IA 52317.
