    No, dry eyes and astigmatism are two different eye conditions. When a person’s cornea, the clear, dome-shaped tissue that covers the front of the eyeball is more oval or egg shaped like a football instead of round like a basketball, and it creates two focal points instead of one, and light rays entering the eye are focused to a blurry spot rather than a sharp point on the retina in the back of the eye, so astigmatism happens. Nearsightedness and farsightedness can cause astigmatism. Dry eye happens when the eyes are not sufficiently moisturized. It can cause redness, foreign body sensation, tearing, and pain. And it is a different eye condition with astigmatism.

    As fasr as i know, dry eyes are caused by not sufficiently moisturized in the eyes, thus cause to redness, foreign body sensation, itching, tearing, and pain in the eyes. But Astigmatism is caused by the clear, dome-shaped tissue is more oval or egg shaped that make the people get blurry spot when the light enter the eyes. So, they have no any connection to each other. From this point, personally, i don't think dry eyes can cause astigmatism.


    Dry eyes are most possible to affect one's eye sight, such as near sight and blurred vision. But it's hardly to cause astigmatism by dry eyes. An optical system with astigmatism is one where rays that propagate in two perpendicular planes have different flocci. I have astigmatism and every time I must add spectacle lenses power. Astigmatism is an optical defect in which vision is blurred due to the inability of the optics of the eye to focus a point object into a sharp focused image on the retina. This may be due to an irregular or toric curvature of the cornea or lens. Blurry vision, squinting, asthenopia, fatigue, or headaches are the most common signs of astigmatism. If you really find that you get astigmatism, you can correct them by wear eyeglasses, contact lenses and refractive surgery. After I checking out astigmatism, my oculist warned me to wear eyeglasses to correct them until they are okay.

    If the eye in different warp of refractive status or the diopter is not consistent, especially corneal surface curvature radius is not a spherical, you may easily get astigmatism. The eye is in the absence of control mode. The eye of different warp inflectional after in the retina can't form a focus. And the formation of focal line is not similar as ones with normal eye sight. Thus, the retina of the objective image blurs the refractive error state which is called astigmatism. Usually people with astigmatism are born to be. However others may get this because of bad use of eyes. If you get astigmatism, you will find that your eyes may easily get dry. You'd better not use eyes in front of computers for a long time. You could use the eyes drops often and use warm compress to release the eyes.
