Of the myriad problems that may occur in vision, some of the more common ones are blurriness, blind spots and floaters. Objects appear blurred when the capacity of the eye to focus wanes. Blind spots are holes in the visual field due to local insensitivity of the retina. Floaters may occur due to a variety of reasons as well.
If you experience any of these problems, you must make it a point to visit your doctor, because many serious systemic diseases, like diabetes, or high blood pressure, could lie behind these seemingly innocuous symptoms.
