Prolonged exposure to bright screens may also contribute to long-term issues like digital eye strain and the development of vision problems such as myopia.
Scientific studies on screen brightness and eye strain
Numerous scientific studies have investigated the relationship between screen brightness and eye strain. Researchers have found that increasing screen brightness leads to a higher level of eye strain compared to lower brightness settings. One study even found that reducing screen brightness by just 10% significantly reduced eye strain and improved visual comfort.
The anatomy of the human eye and screen brightness
To understand how screen brightness affects the eyes, it is essential to consider the anatomy of the human eye. The eye perceives light through the cornea and the lens, which focus the light onto the retina at the back of the eye. Prolonged exposure to high screen brightness can overstimulate the photoreceptor cells in the retina, leading to fatigue and strain.
How the eye perceives light
The eye perceives light through specialized cells called photoreceptors. Two types of photoreceptors, rods and cones, are responsible for vision. Rod cells are highly sensitive to low levels of light and are responsible for peripheral and night vision. Cones are responsible for color vision and detail, especially in bright light. When exposed to excessive screen brightness, these cells can become fatigued, leading to eye strain and discomfort.
Prolonged exposure to screen brightness and the eye’s health
Prolonged exposure to high screen brightness can have negative effects on the overall health of your eyes. Over time, it may contribute to the development of conditions such as digital eye strain, which can cause dry eyes, irritation, and blurred vision. It can also lead to eye fatigue and an increased risk of developing myopia, particularly if you spend a significant amount of time in front of screens without breaks.
