I have a weird gray floater in my right eye. Over the course of the day, it has become more noticeable and tonight, driving after dark, I have occasional bright flashes in my peripheral vision. My night vision is considerably diminished. Now, trying to read my computer screen, I see a diffuse sea of tiny black specs floating in my vision field. It s like looking through a fine mesh screen. Is this a medical emergency? I am out of town.... on a Friday night. Thanks
