Am I in the severe astigmatism range?!
Question: So I'm looking at my eye prescription and I have no idea how bad my astigmatism is.
Right eye : -4.75 -3.75x165
Left eye: -7.00 -2.75x010
Is it that bad? What's the number cut off between moderate astigmatism and severe astigmatism? Which decimal number accounts for the severity -- the decimal number before the "x" or the decimal number after?
Can I still order colored contacts with the same power but without the astigmatism numbers? I need your expertise!

There's no official marker for severe astigmatism and, provided it's regular astigmatism giving a good optical correction, and is not progressive, suggestive of keratoconus, the amount is not terrible medically significant.
The most practical issue is the availability of disposable contacts which becomes more restricted with anything over -2.00, and over -3.50 there are few ready-made lenses and custom ones are usually required.
The number after the x (axis ) is just a compass orientation in degrees and 10 is no better or worse the 170 (both meaning 10 degrees off the horizontal, with opposite inclinations.)
It reports the direction in which the astigmatic component needs to be applied.
Your astigmatic element is sufficiently large that leaving it out of an Rx would make a significant difference. To a rough approximation, it would lose you four lines of a test chart in your right eye and three in your left, possibly more depending on your pupil size and other factors.
Contacts could be made for your Rx with colour and toricity but only, I think, as custom lenses. Durasoft 3 Optifit Toric Colors, for example, but you'd need a specific Rx from your practitioner. The axis direction may not be the same in contacts as spectacles, or from one brand of contacts to another, and it matters.
You shouldn't wear contacts without the proper astigmatism size. I have a slight astigmatism and tried to wear regular contacts that ended up scratching my eye. It's best to get contacts specifically for astigmatism. Fresh look has some, they come in honey, grey, green and blue.
To put it simply, no, you can't order contacts with that prescription....especially colored ones.
Your astigmatism correction is the - 3.75 & the -2.75...contacts would be quite useless for you with out having that part corrected.
That isn't a prescription for contacts anyway...all those numbers would be different for contacts. Even the -4.75 and the - 7.00 would have to be changed in a contact Rx.
That power isn't available in colors as pedestal said, except as a custom made lens. Which aren't disposable, and would cost you way over 200.00 for 1 pair.
You would have to go to the Doctor's again to be fitted with those if you really wanted them.
Yes your astigmatism is pretty bad, but I'm not sure what is really considered "severe." You wouldn't be able to get fresh-look color blends for astigmatism with that prescription because the cylinder on those don't go that high. You might be able to use durasoft optifit toric color blend lenses, those run pretty expensive but have higher cylinders available. Also that brand is a yearly contact so you would only need to buy one pair for the year.
high astis is more than -300 and ur happens to be in that range. Yes, but it will be very blur for u
