Men’s Health Week: 4 Vision Facts You Should Know

Men’s Health Week takes place across Canada from June 15 to June 21. This is an opportunity to highlight some of the unique factors men can face when it comes of their lifestyle, health and vision. We’ve put together some eye facts you may not know that specifically affect men. The goal of this list is to offer some insight and bring awareness to how men might experience their vision differently.  

4 Eye-Health Facts Unique to Men 

1. Colour blindness is more common in men 

According to the Canadian Association of Optometrists (CAOO), 1/10 men have colour deficiency. The reason why colour blindness is more prevalent in men than women is because of how the trait is passed down genetically through the X chromosome.  

Females have two X chromosomes, so if they are unaffected, they will only be carriers for colour blindness, but won’t have the deficiency. Contrarily, males have only one X chromosome passed down through the mother. If that chromosome is affected, they will have colour blindness.

2. Men are more likely to develop an eye injury than women  

A study conducted by the Canadian National Institute for the Blind concluded men reported eye injuries three times more than woman. In the overall study, 8.6% were due to a sport injury, and in 23.1% of the cases, sharp objects accounted for the primary cause of injury.  

Wearing proper eye protection is incredibly important to prevent eye injuries from occurring. CAOO reports over 90% of eye injuries could be avoided if proper safety equipment was worn.  

Wear CSA-certified safety glasses when using power tools, conducting yard work or any activity where there is a high likelihood of flying debris. Read manufacturer instructions when using chemicals and fertilizers for safe-handling instructions.

3. Men can detect visual motion faster than women  

In 2018, researchers found a behavioural sex difference in visual motion perception. In the study published in Current Biology, they asked over 250 participants to determine the direction of movement of black and white bars on a computerized screen. Men were able to identify the motion quickly, requiring only 1/10th of a second. Comparatively, women took 25% to 75% longer. The reason for this difference is still unknown but some researchers speculate that the presence of testosterone may have an impact in visual perception differences between the sexes. The 2018 study will be used as a basis for further investigations in visual motion.  

4. Men are less adept at distinguishing difference in colour 

While men may be faster at detecting motion, women have the advantage when it comes to distinguishing colour hues. In 2012 researchers at Brooklyn and Hunter Colleges of CUNY, compared male vs female eyes in relation to colour detection. On average, they found that men required a longer wavelength of specific hues than woman to experience that same colour. Meaning, their colour detection was less accurate. The scientists also found that men had a larger range within the colour spectrum that they were less adept at discriminating between colours.
