Thanks for your response, Caroline. I know OPCs are supposed to be good for treating glaucoma, but my problem is that I get a severe allergic reaction whenever I try to take them. Grape seed extract seems to be worse for me than pycnogenol. I’ve also gotten similar reactions to red wine extract and resveratrol.

The astaxanthin is interesting. I’ve read a lot of good things about it, but I haven’t tried it yet. I do take lutein with zeaxanthin, and Life Extension has a product that combines all three together in one softgel.
