Bees Are Supplied With Two Sets of Eyes; One for Near, Other for Far Sight

The eyes of an animal can only work together when they can be brought to bear ppon an object at the same time; so that, as a rule, the eyes of a fish must work more or less independently. This is sometimes also the case when the eyes can co-operate, as anyone who watches a plaice or other flat fish in an aquarium will soon discover. _ Many insects possess more than two eyes, which do not act together. A leech, for example, has ten eyes on the top of its head, which do not work in concert, and a kind of marine worm has two eyes on the head and ar row down each side of the body. SOme lizards have an extra eye on the top of the head, which does not act with the other two.

A bee or, wasp has two large, compound eyes, which possibly help each other, and are used for near vision, and also three little simple eyes on the top of the head, which are employed for seeing things a long way off. So that for close sight Inside the hive and for far sight the bees will never need spectacles.
