<p dir="auto">YSK that black backgrounds are harder to read for people with astigmatism</p>
<blockquote>
<p dir="auto">Dark mode can also affect people who have astigmatism, a common condition where vision becomes blurred because of the curvature of the eye. A study published in Ergonomics in 2013 found that for people with standard vision in the daytime, white text on a black background is often better for proofreading and clear vision. <strong>A person with astigmatism in one or both eyes, though, might experience problems reading in dark mode.</strong> People with astigmatism may find that white letters begin to bleed into the black background during dark mode, making them harder to read. It's a phenomenon known as halation. If you can't really focus when your phone's on dark mode, you may need to get an eye test.</p>
