Because the bee’s eye cannot see red, a white phlox blossom looks blue-green. As explained recently by Dr. Kenneth M. McCrea of Bucknell University in Lewisburg, Pa., an authority on insect vision, the flowers look white to human eyes because the retinas are sensitive to red, green and blue, which produce white when mixed.

Dr. Roy Chuck, chair of ophthalmology and visual sciences at Montefiore Medical Center and the Albert Einstein College of Medicine in New York City, said, “We’ve seen lots of cases of laser burns , usually from researchers giving presentations, but now we’re seeing more cases of people ordering these products over the Internet, though eye injuries in lay people are still pretty rare.” Chuck said that children shouldn’t have access to laser pointers. “They’re not giving presentations, so why would they need to have them?” He said that when it comes to laser toys — like those used for laser tag — buying a well-known name brand may be helpful in this case. “When you’re buying off the Internet, it’s not as regulated and you just can’t tell what the strength of the laser is,” noted Chuck. Schmid added that lasers used in toys will generally be labeled as Class 1, although he said that products aren’t always labeled properly.
