The simple eye of the human louse consists of two apparatuses: dioptric and light sensitive. The dioptric apparatus contains only a biconvex lens, which represents local thickening of the cuticle. The eye lacks the crystal cone (Semper cells) and special pigment cells.

- Intracellular recordings from photoreceptors in the cockroach's compound eye revealed two types of cells: UV-receptors (peak sensitivity at 361 nm) and green-receptors (peak sensitivity at 503 nm).
- The spectral response of the whole eye, measured through electroretinography (ERG), showed two peaks around 350-370 nm and 500 nm, with a dip between 400-430 nm.
- These findings support the notion that cockroaches have dichromatic vision, meaning they perceive two distinct ranges of colors.
[Similarity in the behavior of insects and vertebrates in solving difficult visual tasks].

June 1979
Field experiments on elaboration of conditioned differentiation reflex in melliferous bees led the authors to the conclusion on convergent similarity of some characteristics of insects' and vertebrates' behaviour while solving difficult visual tasks. The similarity is expressed in phenomena of 1. "unlearning", or transition to choices at random, during repetitive difficult differentiations; 2.

Majority of cells had the curve of spectral efficiency of 540 nm. This curve coincided practically with the curve of spectral efficiency measured with ERG.
