<s>[INST] Why is having the option for "dark mode" so popular among websites and applications? [/INST] Dark mode is popular among websites and applications because it provides a more comfortable viewing experience for users who prefer a darker screen. Dark mode is helpful for people who have sensitive eyes, as it can help to reduce the amount of eye strain and eye fatigue caused by viewing a bright screen. Dark mode is also beneficial for users who live in areas where energy consumption is expensive - dark mode allows users to reduce the amount of energy used by their screens, which can result in significant savings over time.</s>\ <s>[INST] I heard one time that dark mode is actually worse on the eyes, is that true? [/INST] It depends on the person, as well as the situation. In an enviornment with high brightness, a dark mode might make it harder to read text, causing strain.
