If the blurry light disappears after a few minutes or hours then it is most likely to be due to migraine
( the headache may not be present always, there are variants of migraine with absence of headache). The eye exam is invariable normal in case of migraine. But in case the blurry light persists then it is better to get the eye examined in detail by an ophthalmologist
especially for the back of the eye ( retina and macula
If the macula and retina too are found to be normal, then the most likely explanation for the blurry light is that of posterior vitreous
detachment(PVD).In PVD the thick gel at the back of the eye( called vitreous) gets detached from its surrounding retina . This results in retinal traction which results in the symptom of flashes of light
and includes color distortion. Flashes of light may not be prominent in some individuals. Once the vitreous gets detached completely , it may form clumps or strands and cause symptom of floaters such as dark spots, cobweb or thread like strands in the visual field. More often it is not a serious issue and does not require any specific treatment. A routine retina examination needs to be done by an ophthalmologist just to check for the intactness of the retina and to look for any peripheral retinal tears or holes, which if found, can be sealed by lasers.
Please let me know if you have anything else to ask in this regard.
