Dark Mode has become a go-to feature for many smartphone and computer users, with its sleek aesthetic and dim lighting widely believed to reduce eye strain. However, medical experts now caution that this popular setting might be causing more harm than good.
The Hidden Risk of Dark Mode
A report by TTV News highlights the case of an engineer who preferred using Dark Mode for web browsing and coding. Over time, he began experiencing swollen and uncomfortable eyes.
When he sought medical advice, tests ruled out serious issues like glaucoma. Surprisingly, his symptoms improved only after switching back to a white background.
Dr. Lü Da-wen, an ophthalmologist and director at Taiwans Tri-Service General Hospital, explained that Dark Mode can actually increase strain on the eyes. When using Dark Mode, pupils dilate to let in more light, which, over time, can lead to excessive tension in the muscles around the eyes.
The Science Behind Eye Strain
When the eyes are constantly overworked, it can lead to eye strain syndrome, said Dr. Lü. This is especially true for individuals with presbyopia (farsightedness), where the muscles around the eyes are already under significant tension.
In a dark environment, the pupils naturally dilate. With prolonged exposure to a dark screen, this dilation increases. The constant effort to adjustespecially when transitioning to a brightly lit environmentcan trigger headaches, migraines, or even dizziness.
For older individuals or those with irregularities in their sympathetic nervous system, these sudden adjustments can cause bouts of vertigo, Dr. Lü added.
Expert Advice: Find a Healthy Balance
So, whats the solution? Dr. Lü and other experts recommend sticking to screen settings with natural tones, like white or gray backgrounds. These colors mimic real-world lighting conditions and are gentler on the eyes.
Most importantly, if your eyes feel tired, step away from your devices and allow them to rest. Frequent breaks, proper lighting, and mindful usage are key to maintaining eye health.
While Dark Mode might look cool and feel comfortable at first, its important to consider its long-term impact on your eyes. Could this simple habit be doing more harm than good?
