Unique and Rare Optometry Cases
Most of us think of eye features only in terms of whether or not they can see clearly with or without corrective lenses. Other than the itching and burning when we spend too much time looking at a computer screen, we’re pretty oblivious to the workings of our eyes. However, for a few of us who have a rare optometry situation, life is a bit different. Here are a few of the unique and rare optometry cases that some people face in their daily life
- Colour Blindness – This condition is mostly determined by an X chromosome recessive gene that is hereditary in nature. Because it is in the X chromosome, women are less likely to have colour blindness as they need two of the recessive genes – one from mom and one from dad. As a result, less than one percent of women experience colour blindness. Men, on the other hand, only need one X chromosome, so roughly eight percent of men are colour blind. There are different types of colour blindness, with red/green being the most common and blue/yellow being rarer. The rarest is monochromacy, which leaves only shades of gray. Corrective lenses can be used to minimize the effect of colour blindness in cases that aren’t too severe.
- Heterochromia – This rare optometry case affects only 6 in 1,000 people. Heterochromia is when a person (or animal) has two different eye colours. It can occur at birth genetically or develop later in life because of trauma or disease. If you’ve had it develop, it is important to visit an optometry professional. There are different categories of heterochromia. Some cases have completely different colour irises, while others have just a patch of a different colour or a ring around the pupils that is different.
- Blindness – Blindness can be from birth or happen later in life from disease or injury. It is the most drastic and difficult of all optometry cases in terms of lifestyle adjustments to be made. One of the best ways to avoid later-life blindness is to schedule regular optometry visits and follow the advice given for good eye health.
