I have practiced actual sun gazing in the past and it helped lower my eye pressure (glaucoma) some, but not enough to heal the issue.
Warning: If anyone tries to look at the sun for long perioeds of time, you must do it exactly right, or you could injure your eyes severely! Usually the directions are to start when the sun is going down at evening or coming up in the morning, and you do it for only a short time like ten seconds. Each day you add a few seconds and reach 30 minutes or more. I did this myself and it did not injure my eyes, but I did it according to the instructions of experts in the field.
My recommendation is don't try it until you have done your own research thoroughly. I have also gazed at the sun with my eyes closed and it is a very warm, energizing feeling. Just my two cents.
