A dropping heart rate is a sign that your mind is calming way down. The same thing happens to me. Heart rate and blood pressure both drop. It is connected to the breathing rate. If you can reduce your breath rate down to 1-2 times a minute you can feel extreme calmness but it will greatly lower the heart rate. Just do some vigorous yoga or exercises after the meditation session to get the blood pumping again. Not sure about the eye issue. Maybe try open eye meditation.
