What kind of blinds and which direction. Mini blinds. In width, draw the blind all the way up, hold tightly, and a hacksaw can be used to cut the ends. A power miter saw can be used if you hold the blind VERY tight and go VERY slow on the cut. If not experienced I would use the hacksaw. You can only shorten them by about 2 inches in width. In length, the bottom rail come off, shorten how ever much needed and reinstall the the bottom.

Which color do colored blind people read best?
Revision: Just because you are blind doesn't mean that you are illiterate. Blind people read braille.
Another answer
Probably a bold black color. Being colored blind you can still see, it just means you can't see certain colors. These people don't need to use braille
What color can color blinds not see?
Red and Green
There are many different forms of color blindness. To keep the answer brief, though, there are 3 basic types of deficiencies: Red-Green, Blue-Yellow, and Monochromatic. The most common form is red-green color blindness, also called Deuteranopia.
In my opinion, this is a very hard question to answer because you are asking what someone perceives, which can be caused both by the cones in your eyes as well as the brain. As a person with a color vision deficiency, I have problems telling the difference between red & green, blue & purple, pink & red, yellow & red, yellow & orange, and dark green, dark brown, and black.
An analogy that I have often used to describe how colorblind people see the world uses a paint palette. People with normal color vision have the same three colors on their paint palettes. People who are colorblind usually have three colors as well but they are not as divided. So, when mixed, the colors are not as distinctive as a person with normal color vision causing the color confusions.

What is the best type of solar pool cover blue bubble or clear diamond or other?
blue bubble, dark asorbs heat white or clear reflects it, 2nd Opinion Answer: I do not agree with blue bubble. I have used both and the clear diamond solar cover heats my pool beyond anything a blue cover could do. Clear does not reflect it magnifies. Think of you car on hot summer day. When you get in your car it is like an oven from the sun going through the windows. My pool gets so warm with the clear cover I have to add water to cool it down. Pool reaches 90 with ease. Once I had an extra 2 foot by 30 foot strip and I layed it on grass to use as a slip and slide. Big mistake! It burn my grass in minutes like a giant magnifying glass. I am still debating if the clear diamond is better than the clear bubble because the diamond only lasts a couple years then it falls apart. You have to cover it when you have it rolled up or the sun will kill it. FAZD...
What is the cure for damage optic nerve?
Nerve damage is very difficult to repair. Currently there are no treatments that are widely used, though several procedures are being researched. The foremost of these is stem cell research.

Color blindness is hereditary . It is a defect that limits the ability to see different colors. Some people can't see the color red. But environmental that I am not sure
Blue with white, add small amounts of blue to white until you reach your desired shade. It is easier and will use less paint if you add the darker colour to the lighter colour.
How is the term color blindness misleading?
It is a misleading term because people with color blindness are not blind. Rather, they tend to see colors in a limited range of hues; a rare few may not see colors at all.
What do total color blind people see?
That depends on the type of color blindness. There are three basic variants of color blindness.
Red/green color blindness is the most common. The affected person cannot differentiate between red and green.
Blue color blindness is an inability to distinguish both blue and yellow, which are seen as white or gray. It is quite rare. A total inability to distinguish colors is exceedingly rare. These affected individuals view the world in shades of gray. They frequently have poor visual acuity and are extremely sensitive to light, which causes them to squint in ordinary light.
it is different for different people
according to the trichromatic theory, color information is processed in the brain by comparing the relative activations of three different types of cone receptors in the retina. these three types of cone receptors are either sensitive to blue, responding best to short wavelengths of light, green, responding best to medium wavelengths, or red, responding best to long wavelengths. when colorblind, one or more of a person's cone receptors may be "filled" with the wrong photopigment color. this leaves less functional cone receptors. therefore, dichromats (people left with only two types of cone receptors) are incapable of distinguishing between some or all colors, depending on which cone receptors are lost. for instance, if the green cone receptor is accidentally "filled" with blue pigment then the ability to see green is lost. that person would only be able to blue and red and their derivatives. so, the colors a colorblind person can see all depends on which cone receptor color(s) are missing.
I am colour-blind because i can't see the colour green, but it doesn't show a diffrent colour, it hurts my eyes it is a blur. but i can still see it but not very effectively. I can see all the other colours but just not Green.
I hope this has answered your question
Well They Can See Black nd Only Black Because My Uncle Is Blind And I Asked Him One Day And He Said He Could Only Se Like Black When You Close Your Eyes Soo There You Go :-)
If you are color blind to all colors, your vision will be in black and white, (the colors you will see are black in the range from black to white). If you are only to a certain color, that certain color will be seen in black or white, depending on the shade. Hope it helps! :-)
There are two types of color blindness. The one I know about, is red-green. Its where they tend to flip these colors. People who are color blind don't technically see only black and white, they just confuse most or all their colors.
if your colour blind there are few colours you can see. Some people can't see dark others light, It depends on what you can and can't see. I have a friend and he can't see fluorescent colours. some may only see grey , black and white. Some may see blue and green
Contrary to popular belief, only a rare percentage colorblind people can only see in black and white. More commonly, colorblind people difficulty telling two colors apart, or being able to identify what color an object is. Colorblind people don't see anything "wrong", their perception of color is just slightly different. Only in a minority of colorblind people is colorblindness a major disability.
color blindness, apart from popular belief, is not the condition where you can only see black and white or shades of grey (this is only in extreme and rare cases.) a color blind individual can see most colors perfectly fine. the most common colors people have trouble distinguishing would be red from green (and sometimes brown), and purple from blue, and sometimes dark yellow with light green. although in my case of color blindness it is so mild that i can tell what any color is, i just can't those damn plate color tests. color blindness sucks, especially if you want to join the military! hope this answered your question.

Is the best color of solar cover black blue silver or clear?
I was told by a pool supply store in Cleveland, Ohio, that they have heard of more instances of the black covers falling apart than the others. The guy in the store suggested it is because the black absorbs more of the sun's heat, causing the more rapid breakdown in the material. He had heard nothing about the clear covers, but speculated that it would hold up better than the black. Swimming pool covers help retain pool heat by reducing evaporation. For this purpose, color does not matter. At night any cover will have about the same effect. During the day though, solar energy from the sun heats the pool. You see all sorts of claims from cover manufacturers that their blanket "heats" the pool. This is false. All blankets block some of the solar energy coming from the sun. So which one blocks it the least? According to a government report I read, clear covers block 5-15% of the sun while colored ones block 20-40%. It's clear that clear is the way to go (sorry about the pun). The question then becomes, should I uncover my pool during the day when it is not in use? It depends. On calm, humid days, take it off for maximum heating. On dry, windy days, the evaporation loss outweighs the cover loss, so leave it on. Always leave it on on cloudy days and at night. Dave O
