These videos are fantastic, thank you. I am going through a retina wrinkle and flashes in my left eye. Something I never thought of happening at 62 years old. I wish you would do a video of how sarcoidosis effects the eyes. A disease I didn't even know I had until it effected my eyes.
Superb videos.. I would appreciate to see and hear an expert opinion from Dr. Blackwell on a trend to use the color combination balls in a sport... In past - until 1988 was used a white official FIVB ball in volleyball indoor... Nowadays v. balls are yellow with blue/or green pattern...This unfit pattern contributes to some unpleasant properties. Those balls function similar as a Newton disc...They create disappearing and blurring optical/visual illusions on PC screens when are quick and rotate. Moreover they do not have a contrast from surroundings.. It seems that officials do not care on health, sight, eyes of fans . Moreover this sport has lost the sponsors and access to TVs...
Great work on all these videos, thorough, thoughtful and very accurately presented on all parts!
