Just a foreward: I've read through everything I could find, but couldn't get a straight answer. This new website is kinda annoying, I lost all my bookmarks :p

I wear glasses/disposable contacts. I am nearsighted, same in both eyes. I have a very slight astigmatism, but I don't wear corrective lenses because it isn't significant enough for me to. Would I need a waiver?

Thanks!
 
What’s the prescription of your contacts or glasses?

Also, how can you say you don’t wear corrective lenses but earlier in the paragraph you say you use glasses/disposable contacts?
 
Sorry, meant to say I don't wear corrective lenses for the astigmatism

And the prescription is relatively minor. Ill put it here in a few hours when I get hone
 
Alright, prescription:
Power: -3.75
BC (Base Curve) 8.5

Still looking for an answer, but thanks all.

I'm going to assume the -3.75 is the sphere not cylinder portion of your prescription. If so, then you meet the refraction standards for the USCG.

If you have a certain degree of astigmatism and your prescription takes that fact into account, then there would also be a number associated with the cylinder portion of your prescription. Right now, you've provided only -3.75 but I'll assume it's the sphere.
 
I can give y'all the exact numbers on my contacts. I don't really have anything ekse.

D: -3.75
BC: 8.5
 
You’re within standards.

D stands for diopters and your sphere is -3.75.
 
The prescription doesn't cover the astigmatism. The effect was so minor that it didn't make sense for me to buy new glasses & contacts for them

Plus the contact brand I use doesn't make 1 days for astigmatisms

My guess then is your astigmatism is better than the -1.00 standard for cylinder so you’re good to go there too.

Isn't the -1.00 standard only for being a pilot? I got the following from the USCGA site:

Eyes and Vision
  • Uncorrected visual acuity worse than 20/400 in either eye
  • Vision not correctable to 20/20 in either eye
  • Refractive error exceeding plus or minus 8.00 diopters (spherical equivalent)
  • Astigmatism exceeding 3.00 diopters and anisometropia exceeding 3.5 diopters
  • Refractive error corrected by orthokeratology, kerato-refractive, PRK, laser or any other corneal enhancement

You are correct. Aviation is -1.00 diopters for cylinders (astigmatism).
