I recently had a whiplash injury to my neck, and since then my vision has got darker and goes in and out of blurry, the quality of hd images or videos no longer look sharp anymore. ive had an mri on my brain and orbits and come back clear. ideas?

Some of the responses, might be delayed. A visit to the Ophthalmologist and possibly a Neurologist, should be considered; MRI not withstanding

Please get a completed dilated exam with an Ophthalmologist to determine the reason for this .

I too, would strongly urge visit to ophthalmologist, as your neck injury may have included trauma to the eyes.
