This is a difficult question to answer. Obviously too much light can damage the eye, which is why you should not look directly at the sun, but it is very difficult to quantify, as amount of damage varies with wavelength and length of exposure. It's often the uv light, which we can't even see, which does the most damage. If there is less light than this, then the eye is extremely adaptable and can work at a wide range of light intensities. The iris controls how much light gets in, opening the pupil wide in dim light, and we have two types of light receptor in the retina, rods, which operate well in dim light and cones, which work best in bright light.
What else can I help you with?
How much light should you let get into your eye a day?
A length of 500 m a day maximum
What is the name of the eye that controls how much light passes through the pupil is called the?
the colored part of human eye that controls how much light passes through the pupil is called the?
How much light do eye lids block?
About 75 %
Where should light be refracted by the lens of the eye in order to achieve clear vision?
Light should be refracted by the lens of the eye onto the retina in order to achieve clear vision.
How would you appply make up to bring out green eyes?
wear dark eye shadow if you have light eyes you should wear dark eye shadown and if you have dark eyes you should wear light eye shadow.
When the lights in a room are dimmed the eye adjusts to let in as much light as possible Which part of the eye is most likely to be involved in this process?
The iris is the part of the eye that controls the amount of light entering. When the lights are dimmed, the iris will dilate to allow more light into the eye for better vision in low light conditions.
Why do pupils in your eyes grow larger in the dark?
Just like the aperture on a camera, your pupil dictates how much light is let into your eye. So when you shine a light in your eye your pupil gets tiny, and in the dark your pupil gets large to let as much light in as possible so you can see better.
The colored part of the human eye that controls how much light passes through pupil is called?
the colored part of the human eye the controls how much light passes through the pupil is calles the
The coloured part of the human eye that controls how much light passes through the pupil is called what?
The colored part of the human eye that controls how much light passes through the pupil is called the iris.
Does the pupil absorb the light?
The pupil is actually the absence of the iris (colored part of the eye), so it only allows light to pass through it and helps control how much light passes to the back of the eye.
What type of eye protection should you wear when using high intensity light?
When using high intensity light you should use eye protection that is designed to reduce the light intensity sufficiently that your eyes will not be injured. Selecting the correct eye wear requires knowing how bright the light is and at what wavelengths the light is produced. Just picking up a pair of dark glasses may not provide the needed level of protection.
What is the sensor in your eye that tells you there is not much light?
The sensor in your eye that detects low light levels is called the rod cells. These cells are responsible for vision in dim lighting conditions, allowing you to see in low light.
