10 Things Only The Colorblind Would Understand

10 Things Only The Colorblind Would Understand

Most people dismiss colorblind people as having a minor problem with red and green. As we shall see below, color vision deficiency (CVD) is not as simple as that! About 8% of males (one in twelve men) have this condition while females suffer more rarely from it (5%). While it is normally an inherited condition, many people may suffer from it later on in life when it is caused by other illnesses such as diabetes or as a side effect of medication. Here are 10 things that the colorblind will understand only too well. It is much more than an eye health problem.

1. People think their world is only in black and white.

When people see the world in black and white, this is not the usual color blindness at all. It is a condition known as achromatopsia and sufferers see the world in different shades of grey. It is rather like viewing the world on an old black and white TV. Fortunately, this condition is very rare and about 1 in 33,000 people are affected.

2. People think the colorblind mix up red and green.

It would be great if it were that simple. They think that they just get their reds and greens confused. But, if you look at the actual cause of color blindness, it tells a different story. The eye has certain nerve cells, called cones, in the retina which can differentiate color. When this is defective, the eye fails to pick up the red elements so the colors of red and green appear to be the same color, a shade of light brown, in many cases. Another example of this red/green color blindness is that there is difficulty in seeing the red element in purple so they will have problems in distinguishing blue and purple.

3. People think it is a minor problem.

Many people dismiss color blindness as a minor disability. But the reality of life tells a different story. Colorblind people have difficulty when they do not realize their child may be getting sunburnt! They may have problems when gardening or when they have to prepare food, not to mention when buying clothes. Laying the table may become problematic when they select the ketchup instead of the chocolate sauce for the dessert. Glasses which can help block glare can usually help a little in better distinction of colors.

4. Colorblind children have problems with food.

Imagine telling a colorblind child to eat up his spinach. The problem is that it appears to him as a rather unattractive brown color which will remind him of something else which is totally disgusting. Similar problems arise when they have to distinguish between an unripe green banana and a nice yellow ripe one.

5. People think that colorblind people can adjust easily.

In many cases, colorblind people adjust and they can tell the difference between red and green traffic lights by their position. But, in many cases, their choice of career can be limited as they will have problems with colors. Becoming a fashion designer, graphic designer or an electrician are usually impossible for people with this condition.

6. Effects on the business and the economy are rarely taken into account.

It is only recently that the idea of changing colors in reports, graphs, presentations, brochures, colored house plans and maps to become more color-blind friendly has begun to make an impact. The truth is that all this colorful information may not be fully accessible for a small minority, around 10%. If the reds and greens are seen as brown, it may be impossible to fully understand a report, graph or a PowerPoint presentation.

7. Food marketing needs to take color blindness more seriously.

We seem to live in a red/green world. From traffic lights to the green economy and food packaging these two colors are everywhere! Let us take an example from supermarkets which use a red/green traffic light system which warn people of levels of fat, salt and sugar. A quick glance to spot the red colors which are unhealthy will do for most of the population. But for those who are suffering from CDV, then they have to read the actually detailed info on the label which is usually far too small anyway. This will affect about 5% of customers.

8. LED lights are infuriating.

Most warning systems use red and green to signal that a device is on standby. The red/green system is also used to indicate whether a battery needs charging. For the colorblind, this can be frustrating to say the least because they never know what is really happening. It is always the same old color!

9. Working in a safe environment is important.

Most employers have never even bothered to reflect on whether their premises are actually safe for the colorblind. Are the warning signs for health and safety using color as the main component? If they are, then this may lead to accidents. Health and safety authorities in the UK warn that under sodium lighting, red is not easily read by people with normal vision.

10. Using a computer with colorblindness.

British Telecom have issued a short guide for web designers to help make their pages more color-blind friendly. Keeping in mind such things as luminosity with background will make the text more readable. This is an excellent initiative because most web designers have never even taken this into consideration. It is high time they did!

Are you or a loved one color blind? How do you cope? Let us know in the comments.

How to Tap Into the Power of Positivity

How to Tap Into the Power of Positivity

As it appears, the human mind is not capable of not thinking, at least on the subconscious level. Our mind is always occupied by thoughts, whether we want to or not, and they influence our every action.

“Happiness cannot come from without, it comes from within.” – Helen Keller

When we are still children, our thoughts seem to be purely positive. Have you ever been around a 4-year old who doesn’t like a painting he or she drew? I haven’t. Instead, I see glee, exciting and pride in children’s eyes. But as the years go by, we clutter our mind with doubts, fears and self-deprecating thoughts.

Just imagine then how much we limit ourselves in every aspect of our lives if we give negative thoughts too much power! We’ll never go after that job we’ve always wanted because our nay-saying thoughts make us doubt our abilities. We’ll never ask that person we like out on a date because we always think we’re not good enough.

We’ll never risk quitting our job in order to pursue the life and the work of our dreams because we can’t get over our mental barrier that insists we’re too weak, too unimportant and too dumb. We’ll never lose those pounds that risk our health because we believe we’re not capable of pushing our limits. We’ll never be able to fully see our inner potential because we simply don’t dare to question the voices in our head.

But enough is enough! It’s time to stop these limiting beliefs and come to a place of sanity, love and excitement about life, work and ourselves.

So…how exactly are we to achieve that?

It’s not as hard as it may seem; you just have to practice, practice, practice. Here are a few ideas on how you can get started.

1. Learn to substitute every negative thought with a positive one.

Every time a negative thought crawls into your mind, replace it with a positive thought. It’s just like someone writes a phrase you don’t like on a blackboard and then you get up, erase it and write something much more to your liking.

2. See the positive side of every situation, even when you are surrounded by pure negativity.

This one is a bit harder to put into practice, which does not mean it’s impossible.

You can find positivity in everything by mentally holding on to something positive, whether this be family, friends, your faith, nature, someone’s sparkling eyes or whatever other glimmer of beauty. If you seek it, you will find it.

3. At least once a day, take a moment and think of 5 things you are grateful for.

This will lighten your mood and give you some perspective of what is really important in life and how many blessings surround you already.

4. Change the mental images you allow to enter your mind.

How you see yourself and your surroundings make a huge difference to your thinking. It is like watching a DVD that saddens and frustrates you, completely pulling you down. Eject that old DVD, throw it away and insert a new, better, more hopeful one instead.

So, instead of dwelling on dark, negative thoughts, consciously build and focus on positive, light and colorful images, thoughts and situations in your mind a few times a day.

If you are persistent and keep on working on yourself, your mind will automatically reject its negative thoughts and welcome the positive ones.

And remember: You are (or will become) what you think you are. This is reason enough to be proactive about whatever is going on in your head.
