Symptoms of Optic neuritis

Pain: most people with optic neuritis have eye pain that worsens with eye movement. This is sometimes perceived as pain behind the eye. 

Blurry vision: most people experience reduced vision that appears within hours or days, and usually recovers within a few weeks. The degree of vision loss varies, and in some cases may be permanent. 

Loss of visual field: dark areas may appear in any part of the visual field, but often in the central zone.

Loss of colour vision: optic neuritis often affects colour perception. Colours may appear dulled, as if there was less light.
