Smartphone Self-Test for Eye Health: 10 Seconds to Know Results
SingTao · 1 SOURCESabout 2 hours ago5 MIN
Summary
A Japanese TV program has introduced a simple smartphone-based method to check eye health in just 10 seconds. Japanese ophthalmologist Dr. Morioka Kiyofumi explains that photographing your eyes in low light can reveal whether you have red eyes (healthy) or black eyes (eye fatigue). The program also shared three practical techniques to relieve eye strain that Hong Kong residents can use anytime, anywhere.
Key Points
- The self-test uses a smartphone camera to photograph your eyes in a dark room; red pupils indicate healthy eyes while black pupils signal eye fatigue
- Dr. Morioka Kiyofumi, speaking on the TV program "Before and After Being Taught" (教えてもらう前と後), explains that tired pupils lose their ability to dilate properly in darkness
- To relieve fatigue, look at distant scenery—cloudy skies are preferable to clear skies because sunny conditions contain more blue light that strains the eyes
- The recommended compress technique is one minute of cold compress followed by three minutes of hot compress; cold reduces swelling while heat promotes circulation
- For quick relief in 10 seconds, massage the temples using the handle of a toothbrush to relax eye muscles and improve blood flow around the eyes
- Hong Kong's Department of Health notes that six common age-related eye conditions include drooping eyelids, dry eye syndrome, excessive tearing, presbyopia, and floaters
