I have noticed over the past week as the sun goes down right around 2 to 3 hrs before dark my eye site gets real blurry kind of like looking through a glass makes me feel kind of dizzy and out of balance then when its completely dark it goes away and my eye site returns to normal and the dizzy out of balance feeling goes away. It never happens during the day time only at dusk.
Not at all sure, but could you have retinitis pigmentosa? That’s known to shut down night vision eventually, perhpas it just started for you and only affects vision as light levels are varying so much.
