Colored Contacts Prescription For Astigmatism?

Filed under FAQ on advance for astigmatism
Hi I need an optometrist. I have recently been diagnosed with astigmatism in my “left eye”. And I really would like to wear colored contact lenses. I have found several brands that could work with correcting my astigmatism & a variety of colors to choose from such as: Soleko Queen, Waicon, Durasoft 2 and 3.
All these brands allow me to input customized measurements. With that in mind….I want to have a prescription colored lense that won’t show my natural hazel eye color. So I need help from an optometrist on this forum who could suggest which measurement translates the iris part of the eye? And to go higher or lower what’s the range?
The purpose again is to have a custom colored contact made to cover the natural eye color of the IRIS (hazel)… 
(This was for Durasoft 3 Optfit Toric)
DIA 14.5
SPH -3.50
CYL -1.25
AXIS 180
MEDIAN
and
DIA 14.5
-4.25
BC 8.60
Median
The 14.5 is the diameter of the lens, that is what will more than cover the iris.
I hope you realize that you have about a 50/50 chance, or less, that they will work for you, vision wise.
The Opti-Fit torics usually had to be altered from the prescription by as much as 20 degrees in order for it to stabilize where it should. In other words, ordering it at 180 axis doesn’t mean it will sit at 180 on your eye, it may rotate to 10 or 20 degrees either side of the 180, or even more…blurring your vision. Often , in order to get 180, we have to order it at 160 or 170 , or 10 or 20…there is no way to know without a trial fitting.
Torics can’t be bought without having had a trial fit to see what adjustment has to be made , especially the old technology lenses like the Durasoft Opti-fit , which were never that good a toric lens to begin with.
I think you will find that no site is going to send them anyway unless you have a valid prescription for them, and they will check with your Dr.
It’s the same with any toric lens brand, you just don’t know how it will fit until a trial fitting is done. They are a lot more complicated than regular spherical lenses like your other eye.
