Simple eye in invertebrates. A simple eye (sometimes called a pigment pit) refers to a type of eye form or optical arrangement that contains a single lens. A simple eye is so called in distinction from a multi-lensed compound eye, and is not necessarily at all simple in the usual sense of the word. The eyes of humans and large animals, and camera lenses are classed as simple because in both cases a single lens collects and focuses light onto the retina or film.
The normal reaction to a bee sting is a bit of temporary pain at the location of the sting, some itching and some swelling. Some parts of the body are more sensitive than others and swelling is most noticeable on the face. Bee stings are a normal part of life in the country and a normal part of working with bees.ees and wasps and hornets are different in the way they sting and the venom they carry. Hornets and wasps do not leave a stinger behind. Bees usually leave a visible stinger in the wound and it should be removed by brushing or scraping it off as soon as possible to minimise the amount of venom received.
