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.

11 Hidden Benefits of Using Oil Diffusers

11 Hidden Benefits of Using Oil Diffusers

Affordable, relaxing, and healthy, oil diffusers are gaining popularity with people everywhere due to their extensive benefits. Oil diffusers work through the simple process of oil diffusion, which uses heat to turn oil into a vapor that is then spread around a living space. Diffused oil can have several relaxation and health-related benefits, including safe scent-dispersion, mosquito and mold defense, stress relief, and more!

Read on for 11 hidden benefits of using oil diffusers.

1. Safe Scents That Make Sense

Unlike candles or air fresheners, oil diffusers release cleansing molecules into your air that work to purify it, not overload it with unhealthy chemicals. Electronic diffusers also do not pose the fire risk that candles do. Plus, they contain the added feature of interchangeability, which means you change oil types for different scents and health benefits.

2. Stress Relief

Several lab studies have confirmed that diffusing essential oils like lavender have been shown to reduce stress and help relieve anxiety in medical patients. Preliminary studies have also shown that oil diffusers can help alleviate symptoms of depression.

3. Improved Sleep

Diffused oil has relaxing properties that can help people of all ages fall asleep quicker and sleep more soundly. Electronic diffusers not only have the option to mix and match different oil blends (Try a lavender, Bulgarian rose, and Roman chamomile blend to help with insomnia), they also run at a gentle hum that helps relax an agitated mind. Many also come with an auto shut-off feature to help conserve oils once you have fallen asleep.

4. Appetite Control

Much like gum, oil diffusers can help stimulate the senses in a way that works to curb appetite. New research has shown that diffused peppermint oil can help curb appetite by inducing a satiety response within the body. Diffused peppermint oil has also been shown to increase energy.

5. Bacteria and Mold Killing

When essential oils are diffused in the air, they break down free radicals that contribute to the growth of harmful bacteria. Eucalyptus, thyme, and tea tree oils are especially good for this purpose. Diffused oil is also highly effective when it comes to combating fungal yeast threats, as the oil help makes the air inhospitable for yeasts such as mold. Pine and red thyme essential oils are best for combating mold.

6. Decongestion and Mucus Control

Ever tried Vick’s Vapo-Rub? Its decongesting powers come from active ingredients made from the eucalyptus tree. In principle, oil diffusers work the same way as Vapo-Rub, except they diffuse their decongesting vapor all around the room, not just on your chest or neck. Oil diffusers have been known to cure pneumonia in lab mice.

7. Mosquito Repellant

Nobody likes mosquitoes — but when the trade-off means using repellants full of DEET, a toxic chemical that can be especially harmful to children, mosquito control can often seem like a lose-lose. However, scientists have shown that oil diffusers can be used as a safe and highly effective mosquito repellant. Studies have shown that a diffused oil mixture containing clove essential oil and lemongrass essential oil repelled one type of Zika-carrying mosquito, the Aedes aegypti mosquito, at a rate of 100%.

8. Pain Relief

While applying oils directly to areas of your body may be the most effective way to alleviate pain, diffusing essential oils can also be an effective means of pain relief. When we inhale healthy essential oils, they enter our blood stream and can help internally relieve persistent pain from headaches, overworked muscles, and sore joints.

9. The New Anti-Viral

Research into the anti-viral effects of oil diffusion is now just gaining steam. A recent study showed that star anise essential oil was proven in medical experiments to destroy the herpes simplex virus in contained areas at a rate of 99%. Another study showed the popular DoTerra oil blend OnGuard to have highly-effective influenza-combating powers.

10. Improved Cognitive Function

Diffusing essential oils has also been shown to improve cognitive function. Many essential oils have adaptogenic qualities, which can work twofold in soothing us when we’re stressed, and giving our bodies a pick-me-up when we’re feeling down or sluggish. By working to level out an imbalanced mood, diffused oils also help us to focus. There are also several essential oils which have been shown to help balance the body’s hormones. With prolonged use, these oils can work to repair the underlying causes responsible for hindering cognitive function.

11. Money Saving

With ten clear benefits of oil diffusers already outlined, there is one more that should now be obvious: using an oil diffuser will help you to save money. As an anti-viral, bug repelling, and stress-relief solution rolled into one safe product, an oil diffuser used with the proper oils will save you money on products you might otherwise be buying to help cure those pesky headaches or get your kids to fall asleep on time. If you’re wondering just how affordable oil diffusers can be, check the buyer’s guide to the best oil diffusers — you’ll be sure to find one that fits your budget!
