Purple-shaded glasses to spot garden trouble in advance

These plant examining glasses bring technology developed by NASA andthe Department of Agriculture and brings to your humble backyard. Putthese on and you'll be able to see areas of your lawn that may need alittle help long before you'd observe the problems with your nakedeyes. The lenses block out the green reflected by chlorophyll in thehealthy areas of your lawn and garden, causing those areas to show asblack or gray. Any unhealthy spots, deficient in chlorophyll, will showup as pink, red or coral colors. It's the plant equivalent of full-bodyMRIs that detect problems before their symptoms surface.
