Stem cells from one eye show promise in healing injuries in the other.

I've been dealing with vitreous detachment (both eyes) and copious amounts of eye floaters for 2 months. Imagine shaking a snow globe with long stringy blobs and black dots. That's me right now every time I move my eyes. But I refuse to be "crabby". I've experienced miracle healings before by staying positive!

The more perpendicular you look (near side), the less it’s distorted. #SummerOfPhysics (A daily toot on physics in everyday life. That's the plan.) 1/n
It takes a minute for the (#colour sensitive) cones in your #eyes to adapt to the dark - and +10’ for the rods - so, keep one eye closed if you have to go to the bathroom at night. When you switch off the 💡again, that eye has maintained its dark adaptation. #SummerOfPhysics#Optics 12/n
