Nice White Parents. Because the lens is not flexible like ours, an insect cannot focus properly resulting in less detailed view of their surroundings.
However, an insect vision is very efficient when it comes to detecting movement. Today's digital cameras are built using charge-coupled devices, or CCDs, which have millions of imaging units. They are built on flat planar , rigid silicon wafers. But does the camera actually let people see the world the way a bug does?
This helps them snatch their prey. Male flies, in addition to having bigger eyes, have more specialized acuity zones than their female counterparts. He literally stalks her. Humans are pretty good at seeing colors. We can see about 10 million different colors with three types of cones. Insects and crustaceans use opsins to detect light. Mantis shrimp have 16 opsins and were previously thought to hold the world record, being able to see trillions of colors, until some dragonflies butted in.
Certain species of dragonflies were found to have over 30 opsins, but we are uncertain of their specific ability to distinguish colors. Using the mantis shrimp , the color differentiation capabilities of the compound eye is being reconsidered.
In both of these cases, these animals are fast predators and need to be able to distinguish edible things from not edible things. Their resolution may be worse than ours, but they can see harmful and damaging UV wavelengths.
This is used by pollinators many of which are pollinators like hover flies! Insects can also see polarized light, and many use it to navigate and for mating. A flower photographed under white and UV light. The UV image shows the nectar guide for insects like a landing strip. Normally, the inside of the ommatidium is lined with pigment cells. This prevents light seeping into the adjacent ommatida. A fisheye lens photo of the Jefferson Memorial.
