Red or bloodshot eyes are caused by sudden rupture of the superficial blood vessels in the eye. They are not so much of concern, however if you have pain, watering, discharge…then it's a serious medical concern for which you should consult the eye doctor.
Sudden loss of vision is caused by ocular trauma, blockage of blood flow to the retina(venous or arterial occlusion) or separation of the retina from its normal position( Retinal Detachment). You should consult the Ophthalmologist immediately in such cases for the best outcome.
