I posted a photo on August 26th of a grizzly bear and a deer that were in knee deep water and said: The chance of a bear catching deer is so low it is not worth wasting the energy trying. As proof of that statement here is a grizzly and deer almost side-by-side on dry land and still the grizzly has no interest.
Most bears have the equivalent eyesight as humans; however, like humans, there is quite a bit of variation. Some bears have great vision, and some, especially older bears, may have degraded eyesight. But as a general rule, bears see things in better detail than deer, and about the same as humans.
Part of the poor vision myth comes from the fact that because their noses and hearing are so good that they do not rely as much on their vision. If the wind keeps our scent from the bear we are ignored. What about hearing you say? I have noticed that the bars tend to look up the beach to were normal danger might occur and it appears that they also hear the echo of our motors from that direction and do no look toward the boat. Thus good viewing of black bears.
