Well, mine has. A lot. Basically, I can’t see. Contacts AND corrective glasses make the problem almost tolerable, but it pretty much stinks to have less than decent vision. I read this article on mercola.com with great interest. The ‘Bates Method’ seemed a little unusual, to say the least, but otherwise the information about supplementation and foods that might be helpful were all things that I would personally be willing to try. I think our addiction to electronics hasn’t done our eyesight any favors, and I was glad to have the input on brightness and glare that this article provided. Hope you find it helpful. Here’s to better vision!
