Re: Sun Gazing
About 6 weeks ago following a fairly lengthy sun-gaze, I got bright spots that didn't completely go away for about 2-3 days. This sort of freaked me out. Usually I only gaze with the sun virtually on the horizon. It's my understanding that the sun should be 10degrees or lower in the sky, especially when starting out, and I was pushing it at this time as it was maybe 10-14 degrees.
When judging height of the sun in degrees, remember to judge by the actual horizon, and not any mountains/trees/buildings etc... that are obscuring. If you have a view of the actual horizon such as the ocean, a good way to tell if it's 10degrees or less is to see if you can repeat the distance between the horizon and the sun a minimum of eight more times before you reach the point in the sky that's directly above. (ie. If 90deg is the point right above you, sun should be <10deg.)
As for any lingering effects of the long-ish lasting bright spots, I'm not too sure...! But my eyesight feels ok now. Foods rich in vitamin A and bilberry seem to help. If done in moderation and at safe levels, especially when beginning, there's a lot of evidence to suggest that sungazing can really help your eyesight.
