Every comprehensive eye exam at Stonewire Optometry starts off with a basic colour vision screening. This is because approximately 5-7% of men have some form of colour vision deficiency, which might help to explain some of our bad fashion choices we make. Women can also have colour deficiency problems, but it’s certainly much more rare but always worth noting. That’s because most colour vision problems are hereditary in nature, but occasionally colour vision deficiency may be a sign of an ocular disease or side effect of a medication. As such, we always want to know if the problem is new or long standing.
Unfortunately, most men never realize that they have a colour vision problem and only discover it during a job application physical. The police department, fire department, Canadian National Railway, Canadian Pacific Railway, Air Line Pilots, welding inspectors and a host of other professions all require successful candidates to possess adequate colour vision. As such, it’s often a very negative moment in eye care when an optometrist has to inform a patient that they don’t meet the vision requirements for their dream job.
Currently there is no treatment or cure for colour deficiency. However, this may not be the case for long. A recent study performed between the University of Washington and the University of Florida was able to restore colour deficiency through gene modification therapy in monkeys.
