Horizontal Lines Of Light In The Eye

At night, If we watched the lights on the road with eyes half closed, everything seems blurred into perpendicular lines. If you tilt your head, and all lines should be tilted, too, a sign that it happened in the eyes.
The problem here is the reflection of light on a tear in the upper eyelid and lower lip, the reflection of water in miniature. Eyes saw a bright light is normal, because the reflection coupled with tears. When eyes almost closed, tears flooded fit directly in front of the pupil, so the reflected light formed a long lines at the retina.
