Hi all, I have asthygmatism and myopia, and recently heard that asthygmatism could be a problem for becoming an ATP. How serious is it really? I appreciate your responses.

As long as you have the corrective lenses prescribed by a doctor, it shouldn't hurt you at all. I have the same thing, and wear glasses, and with my glasses, I can see just fine. You should consult your local Optometrist and Optician, and find out what lens is right for you.

Ditto to what he said as far as the FAA is concerned. (I've got astigmatism and I'm near sighted. I hold a 1st class medical and it's not an issue.) As far as the Columbian regulations go, I don't have a clue but I would think that it would be easy enough to find out - just go talk to a local aviation medical examiner.

Thanks for the responses. I will try to find what the regs are here in Colombia.

I think I can expect to find something similar to the FAA regulations, many countries seem to have rules alike to those of the FAA. Right?

From what I understand astigmatism just means you don't have 20/20. I have one in one eye, and I'm still PQ'ed for the Air Force... You should be fine as long as they can properly correct it with glasses or PRK...

Astigmatism is not merely not having 20/20 vision. It is caused by an irregularly shaped cornea and is corrected with eyeglasses, contact lenses or refractive surgery. Sometimes incorrectly called a "stigmatism," astigmatism may accompany nearsightedness or farsightedness. Simply put, near or farsightedness is caused by a mis-shaped eyeball; astigmatism is caused by a mis-shaped lense and you can one condition with or without the other.

Regardless, at least in the U.S., most eye problems are not a problem for the FAA as long as you are corrected to 20/40 (for a Class III) or 20/20 (Class I & II).

Nothing to do with aviation, but which kind of measure is this 20/20 or 20/40 ?? What are the meaning of this numbers?

I always wondered about this ...

Thanks

Imagine your eye as a basketball.

If you press on two points of the basketball, you have two focal points in effect. This is astigmatism. We use a cylinder shape in a corrective lense to work this little problem out and get it to basically one focal point, which when then correct with standard powers.

So, with Astigmatism, your corrective power will read: -1.75 -1.25 @ 093

non astigmatic correction will simply be -1.75 (or whatever your correction is)

All of these conditions are correctable to a vision that is basically normal/typical.

I guess 20/20 has something to do with distance in feet. It must be seeing some standard thing (like text, or a figure) at a distance of 20 feet, clearly. 15/20 would mean seeing it from 15 feet which means less clear vision. Just a guess

I think its something...like, if you have normal vision, then you have 20/20 right...but if you have downgraded vision such as I do (I think I have something obscene like 20/400 uncorrected, but I wear glasses)...I think that means that what a normal person can see 400 feet away, I would have to be 20 feet away to see (w/o correction)...

Hi, I'm an Optometrist. Blatant Echo and Jetguy are pretty much on target.


As for 20/20, it's means that at 20 feet, I see what I should see at 20 feet.

Whereas 20/60 means that at 20 feet, I can see what an uncorrected eye can see at 60 feet. THat i the simplest way to explain the "20/20" phenomenom.


As for astigmatism, it's just a very BIG and Nasty sounding word that really means nothing harsh.

Patients tell me thay have stigma, stigmatism and I have even had a few tell me they have the "stigmata"(thats a classic) But the word sounds MUCH worse than the meaning.

Hi Mirrodie (and others..)

Thanks for clarifying the issue... indeed I never heard this kind of measure here... only the numeric terms, like, -1.5 and so on...
