My eyesight kept getting worse
Over time I started seeing the taillights of cars in front of me double. If I had covered my left eye I would only have been able to make out the license plate on the car in front of me at a maximum distance of about five meters. At about ten meters, I could only see the general shapes. When I looked using both eyes, my healthy eye helped compensate for the problems my other eye was having. I also noticed that my spatial vision wasn’t very good anymore. If a car was coming towards me, I had to turn my head to get an idea of how far away it was from me. And any light source would have a very big halo around it.
