Does Vision Use Chemoreceptors?

Chemoreceptors detect the presence of chemicals. Thermoreceptors

Thermoreceptors
A thermoreceptor is a non-specialised sense receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range. ... For cold receptors their firing rate increases during cooling and decreases during warming.

Is vision a Chemoreceptor?

There are four main modalities: the light senses (photoreception; i.e., vision), the mechanical senses (mechanoreception; i.e., touch, balance, and hearing), the chemical senses (chemoreception; i.e., taste and smell), and the electric sense (electroreception) of certain fish.

What sensory receptors are involved in sight?

Photoreceptors are neurons in the retina of the eye that change visible light from the electromagnetic spectrum into signals that are perceived as images or sight. Rods and cones are two types of photoreceptors located at the back of the eye.
