On a compatible device, you can find the Night Shift options by heading into Settings, then Display & Brightness and then Night Shift. This is the resulting screen:<\/p>\n
You can fiddle around with these settings as you see fit. As a general rule, however, the warmer display you are exposed to in the late hours, the better you should be able to sleep that night \u2013 at least in theory. Still, we\u2019re more interested in how Night Shift could affect your eyes specifically\u2026<\/p>\n There is some anecdotal evidence that Night Shift could indeed be relatively eye-friendly; Tech Insider<\/em>\u2019s Dave Smith reports, from his personal experience<\/a>, that \u201cusing Night Shift is definitely easier on the eyes\u201d. However, reactions from eye health experts have been more mixed\u2026<\/p>\n Andy Morgenstern, who chairs the American Optometric Association\u2019s recently-formed technology committee, has cited blue light as a source of eye strain. He has further explained to The Verge<\/em><\/a> that, while blue light doesn\u2019t strictly harm the eyes like UV light, which can lead to cataracts, using Night Shift to lower it could result in fewer instances of headaches, blurry vision and dry eyes.<\/p>\n Nonetheless, Morgenstern has warned that the optimal level of blue light for relieving eye strain is unclear. Therefore, using Night Shift to lower the concentration of this light only incrementally could barely address eye strain at all. \u201cImagine adjusting your medicine to compensate for flavour,\u201d he says.<\/p>\n Also, the excitement around Night Shift could distract from other, arguably bigger risks to eye health arising from avid use of smartphones and tablets. Both Morgenstern and Geoffrey Goodfellow, an associate professor at Illinois College of Optometry, have pointed out that a major cause of eye strain is spending too much time looking at objects at overly close range.<\/p>\n Goodfellow explains that our eyes have a default focus of about 20 feet ahead, and \u201cweren\u2019t meant to stare at something a foot and a half away for hours and hours and hours\u201d. The increasingly common practice of constantly looking up close at things has, Morgenstern says, led to nearsightedness rates going \u201cthrough the roof\u201d during the last two decades.<\/p>\n Still, for all we\u2019ve just said, there doesn’t appear likely to be any harm in using Night Shift regularly, should you have a device that can draw upon it. While using it hasn\u2019t been strictly proven to prevent eye strain or such associated side-effects as headaches, it could still be worth a shot \u2013 particularly if you\u2019re having trouble sleeping, the main issue that Night Shift is intended to tackle. And there\u2019s certainly evidence that a lack of sleep can adversely affect your eye health<\/a>, too.<\/p>\n Of course, you can also keep eye strain at bay by, whenever you are preparing to look at your iPhone or iPad\u2019s screen for an extended length of time, putting on glasses with lenses built to your most recent prescription.
