This is Dr. David

his flashes of blue and black could have been from temporary small blood clots to his brain or eyes.

temporary small blood clots can be called TIA or transient ischemic attacks.

the risks for blood clots increase as we all get older.

he should see his doctor and tell them about these flashes and visual changes and get blood testing for D Dimer to see if he is at risks for small blood clots

he might need ultrasound scans of his carotid arteries and his heart to check for sources of plaques and blood clots as well

he should get an up to date eye exam as well

let me know if you have questions.
