OS - "oculus sinister" means the left eye
OD - "oculus dextrus" means the right eye

The first number is number of diopters of correction your eye needs. A positive number means farsightedness. A negative number means nearsightedness. +050 can also be written as +0.50... This means you are mildly farsighted in both eyes.

In addition to that, you also have an astigmatism (an irregular curvature of the cornea) in both eyes, as denoted by the second and third numbers. The second number measures in diopters the severity of astigmatism that you have. Yours is fairly mild. The third number is the orientation (in degrees) of the astigmatism... in other words, the angle of the irregular curvature.

I'm extremely nearsighted with astigmatism in both eyes.... I learned how to read my prescription a long time ago. :)



You have mixed astigmatism due to irregular curvatures of cornea. In one axis curvature is lesser and in other it is greater than normal. The first number reffers a spherical power, second is a cylindrical power and the third is the axis of second. I think you havn't any loss of vision. You only suffering from headache or feeling tired with a little intensive work of your eyes.



Actually, you aren't farsighted at all just because there is a + sign there.

You have what is called mixed astigmatism. It is mild, and nothing serious.

If you find you have problems with mild headaches and slight blur , then get the glasses.
