Colored spots and sparks in vision 24/7 for over a year? Have had every test possible everything comes back normal. What do you recommend? Help please

Colored spots. You need to work with your doctors to try and find the source. Ask if one of the medicines you are on could be the culprit. Do not stop these on your own.
Stop worrying. If everything has been normal then perhaps you should stop worrying about this and live your life. Not every phenomenon has a pathological cause or a medical explanation.
