The question of how does colour blindness happen? Many people think that colour is something that everyone in the world will see, but in fact it is not a matter of colour vision but something completely different.

Colour blindness is usually not brought on by a single thing but rather a combination of different things. Some factors could contribute to this problem such as being over exposed to the sun (and not allowing your eyes to adjust accordingly) or also being under pressure, both from lack of sleep and also from being on the job. The effects of colour in your life are constantly changing as you go about your daily routine. If you have no idea what colour blinds are then here are some common symptoms of colour blindness. It is best to see a doctor to help in identifying exactly what the cause of colour blindness might be.

One of the biggest causes of colour blindness is the colour that your eyes actually see. Most people who suffer from this condition are actually totally unaware that they even have it. They cannot distinguish between shades of yellow and red and even when they do recognise these colours they are not able to tell the difference between light yellows and dark purples. It is very easy to be unaware that you have this condition and many people can live their lives in complete denial.

The most important thing to know about colour blindness is that is actually pretty easy to diagnose. Although, you might have had the odd “what colour is that” experience where you know that you are seeing something that doesn’t exist, your eye doctor can easily spot this with an eye chart. There are several different ways that your eye doctor will be able to identify your colour blindness, and the different methods may differ slightly from one doctor to another. This is so that your eye doctor can be able to find out which of the different forms of colour blindness you actually have.

One of the major ways that colour blindness occurs is through your genetics. If both parents have been born with this condition then it is more likely that the child that you will become will also have it. However, there are other ways that your eye doctor can help to identify your colour blindness. Your eye doctor will often take a test called a trichromatogram where he or she will look at the colours in your eyes.

The doctor will then analyse the colours that are in your iris and then compare the results to others and how similar they are to the other colours. This means that if you have different colours in your eyes it is much easier for him or her to find the ones that are causing problems for you. If the colors are different then there are likely to be different genes causing the problem. Therefore you will want to speak to your doctor about your colour blindness as soon as possible.
