What does this mean glasses?!
Question: I am reading off my prescription...
I just went to the eye doctor today, and need information.
Right eye: -+25 -200 axis 45
Left eye: -300 +100 axis 145
Also Trifocal and I'm 28...
Middle: +200
Bottom: +400
Eye Doctor told me my vision can only be good at 20/40, What does this mean?
I cannot see close up nor faraway, She mentioned Astigmatism... other than that no idea??

I have just answered your follow up question, but thought I'd stop here.
I agree with the person above that you have probably read or typed the prescription incorrectly. Lets make a few other corrections. There should be a decimal point two places from the right in the numbers 25, 200, 300, 100 and 400. Also the first 200 and the 100 should both have the same sign, since only one refracting instrument was used to test your eyes and refine your prescription. I'll assume that it should have been a minus (-) sign in both. So it should read.
R.E.: +0.25 -2.00 axis 45
L.E.: -3.00 -1.00 axis 145
The -2.00 and the -1.00 indicates how much astigmatism you have. Significant but certainly not a very large amount. The 45 and the 145 are numbers to show how the astigmatism is situated in each of your eyes.
As I said in answer to your later question, this is a strange prescription for a 28 year old. You need an explanation for why your best corrected vision is limited to 20/40 and why you need multifocal lenses. Ask the doctor. Perhaps there is something in your history that you are not telling us.
Astigmatism is when the eyeball or lens is technically mis shaped. It's like taking a paper towel tube and squishing it a little. As for the rest I'm not sure
The 20/40 part means that you have to be at 20 feet from an object to see what a " normal" eye can see at 40 feet.
20/40 means you can still get a drivers licence...but you are right at the limit.
I think you mixed up the + and - signs on one of the eyes ?...the 2.00 on the right and the 1.00 on the left should both either be + or -...not one of each. That changes the whole thing.
That is a strange and rare kind of Rx for a 28 year old.
You are nearsighted and have astigmatism. Mild to moderate in both cases. You don"t need trifocals at your age and I would bet that you will only wear your glasses for a short period of time and will get a distance only prescription for glasses.
it's kind of complicated to explain everything on the prescription, but the first numbers correct your lens (the first part of your eye) and is called the sphere. the second number is the cylinder, and is the degree of astigmatism you have - the higher the number, the more astigmatism you have. that's caused by the eye being more football shaped than perfectly round, and it causes images to be slightly distorted. the axis is the placement of the cylinder, or the astigmatism correction. If you think of a circle labeled with degrees, the axis is the degree on the circle. The middle and bottom are the same as the spherical correction on the main prescription - you need those corrections when your eye muscles aren't very good at changing and focusing at different distances anymore. that's why you need three different corrections.
being corrected to 20/40 means that you can see at 20 feet what someone with perfect eyesight can see at 40 feet. if you remember the eye charts they had you read, it means you probably won't ever be able to see the bottom lines clearly, but you can always just get closer to something or hold a book closer to your face. 20/40 isn't that bad.
hope that helps.
