<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] Helpful in reducing eye strain. Dark mode doesn't directly reduce eye strain, but it can offer some relief. For example, in a dim setting, a bright screen has your eyes working harder. On the contrary, a dark screen in a brightly lit room will have the same effect.</s>
