Intermittent blurred: Vision that varies with blinking can be secondary to dry eye syndrome. This is usually relieved with conservative therapy. Variable vision that varies day to day can be related to many more issues. They vary from cornea disease (abnormal swelling) to retinal disease (diabetic retinopathy). A comprehensive evaluation from your ophthalmologist will be able to pinpoint the exact cause.
