Have your blood pressure checked as retina vessels get significantly affected, sometimes leading to vision loss when you suffer from high blood pressure.

Quit smoking if you can since the over 400 chemicals in that single stick of cigarette aren’t good at all for your retina especially since they may clog it; but eat more fruits and vegetables as these, especially green leafy vegetables, have lots of antioxidants that aid the retina ward off any harmful effects.
