Yes, cataract is one of the reason to give rist to blurred vision in reality. As we know that cataracts occur when there is a buildup of protein in the lens. In that way, it will just prevent light from passing clearly through the lens, causing some loss of vision. And it can be caused by irritants, so at that moment, it will lead to some other eye problems, such as blurred vision. To relieve the symptom, I will suggest that you should not touch eyes unless hands are clean. For the home remedy, you can put a damp, warm washcloth held over the infected eye a few times. In this way, it will do a help to the double vision. At the same time, you'd better use some eye drops with anti-inflammation to let the eyes get release.In addition, you could accept the medical treatment which will make you feel better. Hope you can restored to health soon.
