I'm  regularly wearing glasses since past few years, but since  last 1 week I'm experiencing slightly foggy vission in my left eye. When I look at a street light I see the light around the bulb spreaded, it seem like glare not any halos or starburst. It only happens in my left eye and my right eye is fine that's why I can tell the difference between clear and not clear vision. I'm not having any headaches. I have myopia but I think my right eye vision has improved and left vision has gone down a bit. When I look at a window or something with not very bright light but big source, it feels like I'm looking through a little bit foggy glass. I'm worried and your analysis would definitely help.
