Human eye is most sensitive to(A) Red Colour(B) Green Colour(C) Violet Colour(D) Orange Colour? ›

This curve peaks at 555 nanometers of wavelength which corresponds to green colour in the normal visible spectrum of light, which means under normal lighting conditions, the eye is most sensitive to Green colour. So, the correct answer is Option (B) - Green.

The correct answer is Yellowish Green. The human eye is most sensitive to yellowish-green colour in the daylight. The sensitivity of the human eye to light of a certain intensity varies strongly over the wavelength range between 380 and 800 nm.

The human cornea is probably endowed with the greatest density of nerve fibres of any tissue in the body. For this reason it is assumed to be the most sensitive structure (1) a characteristic which is, of course, essential to elicit the palpebral reflex which shuts the eyelids and therefore protects the eye.

The measurement of the light wave is in wavelength. The figure 1 shows the relationship between eye sensitivity and colour wavelength and colour luminosity. From figure 1, green proves to be the most sensitive to our eyes while red and violet proves to be the least.

As we mentioned above, the human eye has three types of cones that allow us to see a certain range of light and, therefore, colour, on the electromagnetic spectrum – i.e. the visible light spectrum. These colours are blue, green, and red. But obviously, we see much more than just these three colours.

Lighter-colored eyes have less pigment to protect against sun damage and UV radiation compared to darker-colored eyes. This means that people with green, hazel, or blue eyes are more sensitive to light and more susceptible to UV damage.

The human eye is most sensitive to light in the middle of the spectral range. (500 to 550 nanometers). This approximates to green/yellow light.

Generally speaking, patients with lighter color irises, such as blue or gray, experience more light sensitivity than someone with brown eyes. The density of pigment in light eyes is less than that of a darker colored iris. When light hits a dark-colored iris, the higher density in pigment blocks the light rays.

Any bright light source, such as sunlight or artificial light, may cause discomfort. Light sensitivity may be a symptom of certain eye conditions or due to a migraine or a bacterial infection such as meningitis. Sensitivity to light can also be a temporary response following an eye procedure or surgery.

The human eye is most sensitive to yellow-green light having a frequency of about 5.45 10 Hz (a wavelength of about 550 nm).

How sensitive is the human eye to green? ›

A curve is obtained which shows the response of the eye under normal lighting conditions. This curve peaks at 555 nanometers of wavelength which corresponds to green colour in the normal visible spectrum of light, which means under normal lighting conditions, the eye is most sensitive to Green colour.

The sensitivity of the eye falls off as wavelengths get longer (redder). or shorter (bluer). Violet light has an even shorter wavelength than blue light, so it is farther from the wavelength of maximum sensitivity than blue light.

Colors that Grab Attention

As a bold color that stands out, it's easily noticeable, even from a distance. In addition, red has been shown to increase the heart rate and stimulate the brain, making it a powerful aid in attracting attention. Blue is another notable color for catching the eye.

Colors with shorter wavelengths (blues especially) tend to produce more eye strain than colors with longer wavelengths (like red and orange).

Yellow, pure bright lemon yellow is the most fatiguing color. Why? The answer comes from the physics of light and optics. More light is reflected by bright colors, resulting in excessive stimulation of the eyes.

Most Common and Rarest Eye Colors

It shows up in about 9% of Americans but only 2% of the world's population. Hazel/amber is the next rarest color after green. Blue is the second most common and brown tops the list, found in 45% of the U.S. population and possibly almost 80% worldwide.

Cheerful sunny yellow is an attention getter. While it is considered an optimistic color, people lose their tempers more often in yellow rooms, and babies will cry more. It is the most difficult color for the eye to take in, so it can be overpowering if overused.

In daylight, green is the most visible color from a distance for human eyes. In the darkness, however, yellow is the easiest color to recognize. The rods (small structures in the eye) are responsible for sight in low-light situations. And the cons are responsible for high-light conditions.

Red and orange seem to be the clear winner when it comes to eye-catching colors. These colors tend to stand out and are therefore used on many warning signs or safety equipment. Yellow is another color that comes in a close second to red and orange in popularity.
