intro & question

Hello, I am new to the group. My name is Trudy and my husband has epilepsy (almost 30 years now). Most of the time he can avoid things which are triggers, but still has multiple grand mals each week, also several petites each day. Recently several of his triggers have become more sensitive. The one I am seeking help on today is a sensitivity to patterns. One example: our church is in the midst of remodeling, and have torn out the old carpet, exposing the concrete floors, with old glue stains, and patched areas which have been caulked. This causes my husband to go into seizures -to see the scattered patterns the floor makes. We have tried very dark sunglasses, and it has helped a little, but now even that doesn't seem to do the trick. The blind association said they make black out glasses out of safety glasses and paint with Krylon Fusion. Currently I lead him around while he closes his eyes in the areas where the floor is exposed. But, as I said, it is getting more sensitive, and yesterday he had troubles while riding in the car, to see the patterns on the bridge (not reflecting lights, just the cracks between panels and the weeds growing in cracks, etc). Are there other options to reduce his sensitivity other than forcing him to be blind? I read the article about fireworks (which defintiely do send him into seizures) and saw the suggestion that the pattern be less than half the visual field. Great idea and we will try to do that when possible, but I am not sure how we can apply that here, as my husband has very good peripheral vision, and even when it is off to the extreme side or bottom, it still bothers him. We would rather have some non-medicinal answers as medicine doesn't seem to do alot for him. Thanks for any suggestions!
