Astigmatism is a common eye condition that's easily corrected by eyeglasses, contact lenses, or surgery.

Astigmatism is caused by an eye that is not completely round. This is one type of refractive error. Astigmatism occurs in nearly everybody to some degree. For vision problems due to astigmatism, glasses, contact lenses, and even vision correction procedures are all possible treatment options.

A person's eye is naturally shaped like a sphere. Under normal circumstances, when light enters the eye, it refracts, or bends, evenly, creating a clear view of the object. However, the eye of a person with astigmatism is shaped more like a football or the back of a spoon. For this person, when light enters the eye it is refracted more in one direction than the other, allowing only part of the object to be in focus at one time. Objects at any distance can appear blurry and wavy.

What Causes Astigmatism?

Astigmatism is a natural and commonly occurring cause of blurred or distorted vision. The exact cause in not known.

What Are the Symptoms of Astigmatism?

People with undetected astigmatism often have blurred vision which can be associated with fatigue and eyestrain. While these symptoms may not necessarily be the result of astigmatism, you should schedule an eye exam if you are experiencing one or more symptoms.

How Is Astigmatism Diagnosed?

Your eye doctor can diagnose astigmatism with a thorough eye exam. Astigmatism may occur with other vision problems such as nearsightedness and farsightedness. Because astigmatism may increase slowly, you should visit your eye doctor whenever you notice changes in your vision.

How Is Astigmatism Treated?

Almost all degrees of astigmatism can be corrected with properly prescribed eyeglasses or contact lenses. For a person with only a slight degree of astigmatism, corrective lenses may not be needed at all, as long as other conditions, such as nearsightedness or farsightedness, are not present. If the astigmatism is moderate to high, however, corrective lenses are probably needed.




There wasn't any mention of depth perception or difficulties in seeing 3D images on a 2D screen (which I still would consider that part of your depth perception).

Wikipedia gives a more detailed explanation of astigmatisms (eye).

I also have Astigmatism in both eyes but can see 3d just fine. It's up close where my Astigmatism gives me issues.

There are cases of astigmitism that can't be completely corrected with surgery. I know because I am one of them. Mine is severe enough that the doctor said I'd probably only see about 20% better than without surgery, meaning I would still need glasses.

Besides, I actually like my glasses

That's the best description I've had yet. Thanks as I too have astigmatism for years and sometime I love my glasses and sometimes not too much.
I can see 3D just fine. I don't like the way it's used, but that's something else.

No one can tell me what the other condition is?

Could it be too much superiority of one eye over the other?

I honestly don't know what it is called, but you can mimic some of that condition if you cover 1 eye.

...then he would be Joe The PIRATE!

Arrrgh!!!!!

This is interesting and I know how hard it is to keep up with all the changing technologies so as far as karaoke is concerned I don't even try. It is just a hobby and only for personal use in my case so I'll just stick with the CD+Gs I have and hope they don't wear out before I do.

First, that would mean that eye superiority may have something to do with it.

Second, being Original Manufacturers' Disc based, maybe...um.. Fred the pirate?

Disc vs HD has nothing to do with the graphics showing and whether someone could see them or not.
