National eye week: eyesight can be improved by playing video games, an expert suggests

Reading Time: 2 minutes


Feel Good Contacts believe video games can have a variety of benefits to your eyesight.
Sharon Copeland, Contact Lens Optician for Feel Good Contacts has outlined the four major benefits video games have on your vision:
“Playing video games can benefit our vision in numerous ways, despite contrary beliefs and the bad reputation they have gained. Here are four ways in which playing video games can benefit our vision:
1. Improved visual acuity
Playing video games challenges the eye muscles to move and focus quickly, therefore improving visual acuity. Visual acuity is the clarity or sharpness of vision. Opticians will check their patients’ visual acuity by getting them to do a visual acuity test whereby the patient will be asked to read out letters or numbers from a chart at a distance. It’s normal for our visual acuity to deteriorate as we age.
2. Improved peripheral vision
Playing action games and first-person shooter games such as Call of Duty sharpen and improve peripheral vision.
These games often have real-life settings such as cities and jungles. While the player may be focused on where they are shooting, their brain is absorbing the whole screen, which often features moving people and objects in the background. Therefore, they are training their peripheral vision, which is incredibly beneficial in real life when noticing things such as trees, moving cars or people. We use our peripheral vision when walking and driving, for example.
3. Improved contrast sensitivity
Video games can even improve your ability to perceive and differentiate between shades of grey and improve contrast sensitivity and visual sensitivity to colour. If you have a low visual sensitivity to contrast, you may face a challenge when driving at night, especially if it’s foggy outside. Contrast sensitivity is one of the first visual capabilities to fade as we age. Nevertheless, according to Daphne Bavelier of the University of Rochester, certain video games can improve your sensitivity to contrast in colours.
4. Improved amblyopia
Amblyopia is also known as ‘lazy eye syndrome’ and occurs when the brain cannot process information from one eye and, as time goes on, starts to favour the other eye.
A study has shown that playing video games can help children to improve their amblyopia. In this study, players who engaged in video games while wearing an eye patch on one eye recognised a dramatic improvement in visual acuity after 20 two-hour sessions. The results were compared to another group of participants who underwent the same experiment but shorter. This group noticed dramatically less improvement in their amblyopia.”
