Hello, Welcome to Just Answer
Do you experience any other eye symptoms like floaters, reduced vision?
No. This just began a few days ago, with a sort of color distortion.
The most common cause for flashes of light at this age is posterior vitreous detachment(PVD). In this condition the thick gel at the back of the eye gets detached from its surrounding retina . This results in retinal traction which results in the symptom of flashes of light and includes color distortion.
And just what should I do~ if anything...
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.
Can this develop suddenly? I have just had (last month.) an eye exam, and passed with flying colors!
The only concern is that of a remote possibility of a retinal tear extending into a frank retinal detachment which is characterised by symptoms of sudden increase of flashes or floaters and a curtain or veil falling in the feild of vision. This requires urgent treatment by a retinal specialist.
PVD can occur suddenly at anytime and is a diagnosis of exclusion and does not show any signs as such.
You are welcome.
