I’ve gotten a couple of emails recently asking how to order contacts online, mostly referring to Circle Lenses. The first contacts I ever ordered online were actually NOT Circle lenses. They were my Red Vampire Contacts. My eye doctor helped me with the ordering process and explained to me what I needed to look for when placing an order.

First up, you need to know your base curve, your prescription and normal diameters.
My Base curve is 8.6.
My normal contacts range from 14 to 14.2 in diameter.
My prescription is -9.0 and -9.5.
I also try to go for the highest water content possible because my eyes are sensitive, so usually at least 38%
If you have an astimatism it’s much trickier and you will definitely need your eye doctor’s help. Contacts for astimatism are weighted, so most types of colored contacts aren’t offered in astigmatism format.

My Red Vampire Contacts are completely red, with no black, and they’re larger than the colored part of my eye.
Their diameter is 14.5.
Their base curve is 8.6.
I ordered them in my prescription of -9 & -9 (at the time I wore -9 in each eye).
Their water content is 38%
My eye doctor informed me that because the diameter was a bit larger than normal, that my eyes would get tired faster while wearing them. He also said that because of the way they were shaped, they would color the edge of my vision, which they do. So he recommended that I wear them for no more than 6 hours at a time. My eyes really do get tired after wearing them, and they do color the edge of my vision enough that I’m not comfortable driving in them. However, for wearing around a convention at night, they’re really cool.

When I ordered my Circle Lenses, I made sure to choose lenses that most closely matched my regular contacts in diameter, curve and water content.

My Purple Angel Series lenses are:
Diameter 14
Base curve 8.6
Prescription -9.0 & -9.5
Water content is 38% to 42%

My Geo Nudy Blue are:
Diameter 14
Base curve 8.6
Prescription -9.0 & 9.5
Water content is 38%

My Geo Tri Color Green are:
Diameter 14
Base curve 8.6
Prescription -9.0 & -9.5
Water content is 38% to 42%

My Max Pure Pink lenses match my Red Vampire Contacts in size:
Diameter 14.5
Base Curve 8.6
Prescription -9.0 & -9.5
Water content is 42%
Because the water content is so high in the Pure Pink I ended up wearing them for 13 hours without meaning to. Mostly because they just didn’t tire my eyes out the way my Red Vampire contacts do.

One of the interesting things that I’ve noticed from going to conventions over the years is the number of booths selling specialty contact lenses. Normally they always sell plano (no prescription) lenses, with an option to order from them online for prescription. We bought Ray a really cool pair of cat slit pupiled contacts one year at Dragon Con.

Bear in mind, I am not an eye doctor. If you have any questions about contacts and ordering, you should speak to your eye doctor. Additionally, you should get your eyes examined before wearing contacts to make sure that you can comfortably wear them.
