The eyes primarily detect light signals in the form of visible wavelengths, which range from approximately 400 to 700 nanometers. Specialized photoreceptor cells, known as rods and cones, convert these light signals into electrical impulses that are sent to the brain for interpretation. Rods are sensitive to low light levels and help with night vision, while cones detect color and detail in bright light. Together, they enable the perception of images and colors in our environment.
Our eyes have severl million sensory cells which can detect the light waves coming from any object and on the basis of wavelength of that waves brain transmit the colour signal to the cells of eyes..
Compound eyes detect motion, and simple eyes detect light. or The compound eyes are used to "see". The simple eyes are used to detect light intensity.
The light that our eyes can detect is known as visible light.
Tears are produced by the lacrimal glands in response to emotions, irritants, or to moisturize the eyes. When our eyes detect something irritating, a signal is sent to the brain which triggers the release of tears to help protect and lubricate the eyes.

Your eyes can detect visible light, which is a form of electromagnetic radiation that falls within a specific range of wavelengths. This is why your eyes are sensitive to colors and brightness levels in the environment.
The minimum detectable signal in a radar system is the weakest signal that the system can detect reliably against background noise. It is determined by the receiver's sensitivity and the signal-to-noise ratio of the system. A lower minimum detectable signal indicates that the radar system can detect weaker signals.
Everything except visible light (cosmic, X-rays, radio, infra-red, ultra-violet, etc.).
