Because the vision on the outside is your peripheral vision, not our main vision, and there are less colour receptors around the edges of the eyes.

What do you use the sides of your retina for?
The retina has two types of cells used in vision, rodsand cones. Cones, concentrated in the center of the retina, serve both color vision and the highest visual acuity. Rods, concentrated away from the center -- at the "sides," as you phrased it -- are responsible for night vision, for our most sensitive motion detection, and for our peripheral vision (vision of objects to the side, away from the center). Paradoxically, your night-vision is enhanced it you do not look directly at objects that are in relative darkness. If you drive at night on poorly lighted roads, for example, you can enhance your night-vision of passing cars and of the sides of the road by looking straight ahead: the rods will detect motion, objects on the periphery (the sides), and objects in relative darkness. If you were to look directly at objects in darkness, you would be stimulating the cones, in the center of the retina, and your night-vision would be less effective.
Island a has an area of 30 square kilometers island b has an area of 400 square kilometers the islands are near each otherwhich is the hiest percentage?
Island a has less biodiversity and higher percentage of edge effects than island b.
What are the best contacts if your eyes are getting really dry and blurry and you have astigmatism?
theres: Soft Toric Lenses - Toric lenses have two powers in them, created with curvatures at different angles (one for astigmatism, the other for either myopia or hyperopia). There's also a mechanism to keep the contact lens relatively stable on the eye when you blink or look around. To provide crisp vision, toric contact lenses cannot rotate on your eye RPG(rigid gas permeable) Lenses - Unlike hard plastic lenses, RGP lenses are gas permeable. That is, they allow oxygen to pass through to the cornea. They are less expensive and more durable than soft contact lenses, and provide wearers with clearer, sharper vision. Unlike soft contact lenses, RGP lenses have a low water content and therefore, resist protein deposits and bacteria. Because they are rigid, they hold their shape when the wearer blinks, allowing for crisper vision. Other benefits include ease of handling and ease of care. Because they do not contain water, proteins from the eye do not build up on the lens, so the lens stays cleaner, and requires less maintenance. RGP's are not for every patient. Because of their rigid form, they require more break in time for the patient to become comfortable with wearing the lenses. Also, if you discontinue wearing your RGP lenses for a few days, it may be difficult to become used to wearing them again. RGP's differ from soft contacts in that becoming comfortable with wearing a rigid lens requires the patient to wear their lenses all the time. Soft contact lens users may discontinue wearing their lenses for a few days, and immediately be comfortable with having them inserted again.
Why view transparent cells with less light?
1. to get a slightly better contrast 2. because light is accompanied by heat and it will soon dry the slide
Does eye color effect sun sensitivity?
Yes it does. Your iris determines how much light goes through the eye, and the darker it is, the less light can go through. This affects mostly your peripheral vision, because it helps the rods to work better in "dimmer" light. Does that help?
Why is your vision around the edge less sharp and colourful than your front-on vision?
because of your mum
Is a gyro sharper or a straight cable?
A straight cable will be sharper, have less play in the system.
Why is your vision around the edges of your view less sharp and colourful than you front on vision?
The retina does not have a uniform distribution of sensors, the rods (for low light levels) and cones (for color vision). There is a spot in the middle of the retina called the macula, where sensors are particularly dense. That is why you see more detail directly in front of you, and less detail in your peripheral vision.
What animal has the best eyesight?
Great horned owls have the best eyesight ever.If you placed a newspaper on a chair, a Great Horned Owl could make out every word on that paper from 50 yards away. They can see almost that well in the dark.The sea animal with the best vision is the Mantis Shrimp, which can see in a broad spectrum of light that includes infrared and ultraviolet.In fact, humans could have the best the vision, why? Many animals have special types of vision, for example, eagles have extremely sharp vision, but lack color. Us humans have every single type of vision. Our cones in our eye, see color, eagles' cones aren't as adapted as ours. We can detect around 10 million colors, focus from Miles/km to inches in less than half a second, we have around 180 degrees of vision, sharper vision that a camera, we can see detail in a bright light, or even during night time. Not to mention around 30 frames a second, well that's a rough estimate, as some people can notice flickers of 1/200th of a second. Vision is very tricky, as I said before, eagles may have sharper vision, but us humans... we have it all!
What is a bearing edge on drum shell?
It is the surface of the drum shell that actually touches the drum head. The area of this surface is less than that of a cross-section of the whole shell, since it is created by making an angled cut into the shell around the rim. The thickness or thinness of the bearing edge affects the tone of the drum; finer or sharper bearing edges yield a brighter tone, while thicker bearing edges yield a warmer tone. If the bearing edge is not perfectly level and perpendicular to the cylinder of the shell, the drum head will not seat properly and the tone of the drum will suffer.
Why are dogs bites less dangerous than a human bite?
noot true and dogs have sharper teeth
Why is vision less important for mammals than most wertebrates?
Vision is not less important in mammals than any other family of vertebrates.
What do eye vitamins do for your eyes?
The most common is Vitamin A. The derivative of this is Beta-cerotine which helps to ad pigment to retina which in turn aids in vision. Other vitamins like E and C will help overall too.
Did Edge beat John Cena in less than two minutes?
i think that edge did beat cena in less than 2 minutes because cena was bleeding
Why It is easy to cut vegetable with a sharp knife than a blunt one?
The sharp edge of the knife has less area than the blunt edge. So we are able to cut easily using less strength with a sharp edge of the knife.
Who would wear spectacles?
Someone with less than perfect vision.
Who has better peripheral vision older or younger people?
Younger people mostly have better peripheral vision due to less eye damage.
