I'm an optical retailer, and our computers only allow us to enter a double aspheric lens if the cyl is equal to or greater than 1.00. If it is under, it will only let us enter a regular aspheric lens.
The only lens we have in double aspheric is Trivex.
My question is whether a double aspheric lens would adversely affect anything if the script has a low or nonexistent cyl.
