Visual difficulty may complicate some daily activities such as buying fruit, completing your studies or even some jobs which require color detection as part of their responsibility.

Once visual anomalies have been detected, it is important to see your family doctor or a professional ophthalmologist to diagnose the disorder. Generally, a Ishihara test is usually carried out. This is a medical test carried out with some sheets of paper containing numbers made up of different coloured dots. If your eyesight is regular, you will be able to distinguish the number or figure, whereas someone with color blindness will not. Have a look at the picture below and see if you are able to detect the number 10, your eyesight is fine. If not, you might want to see a doctor for more tests.

One of the best resources to treat color blindness is the use of special lenses. These lenses which have a filter designed to alter the spectrum of light so that the eye receives similar stimuli to those received by a regular eye. Doing so will help improve color blindness and make vision more normal. With these special lenses, colour blind individuals will be able to see more colours and shades which, without them, would be impossible. Corrective glasses are a great option as they are suitable for 80% of colour blindness cases.

As mentioned above, colour blindness is not a serious disorder, nor does it cause significant difficulties in everyday life. However, it is very important to identify eye problems in a timely fashion as they can be decisive when carrying out certain activities, studies or work.

Approximately 1 in 12 men are color blind, but it is much less common for women as only about 1 in 200 have color deficiency. This is because men only have one X chromosome, whereas women have two. For a woman to be color blind they would need to have both X chromosomes as carriers, which is significantly less likely. There are some myths about what types of profession which allow you to work as someone who is color deficient. Depending on your level of deficiency, it is still possible to be an airline pilot, fireman or police officer, although in severe cases they can pose too great an impediment to the job.
