Well, of course not. Dry eyes can not be a sign of the early pregnancy. As we know that if you do not have the necessary balance of these three layers in your eyes, or if your eyes do not make enough tears to coat the eye, you may have dry eye. Generally speaking, there is nothing to do with the early pregnancy. Of course, in some cases vitamin deficiency may contribute to dry eye problems, such as vitamin a deficiency. So if you do not intake enough vitamin A, you may also experience problems with dry eye. To treat it, you can take some foods which are rich in vitamins such as the fishes and some other vegetables. Besides, if you have dry eyes, you may experience scratchiness, itching and burning on the surface of your eyes. So anyway, it can be dangerous. Also, there are also some other reasons which can lead to dry eyes, such as the eye strain.
