What is the natural science reason to wear blue light eyeglasses instead of just turning one’s computer display’s blue lights off or very low in spaces where there are no other sources of blue light than the screen the person is watching? Suppose that the person has perfect visual acuity without eyeglasses. Suppose also that all other possible protective measures achieved by the blue light eyeglasses are achieved by other means, such as by using UV filtering eyeglasses of the same shape and frame material and frame color as the blue light eyeglasses assuming that the blue light eyeglasses do have such protection. Economic, ease of use, technical savviness, time needed to configure the display or other such reasons are out of scope of the question. Other situations where there is blue light are also out of scope just as the overall harm caused by blue light.

    I suppose my explanation is out of scope, but that’s the only real reason that I know of.

    It really isn’t. This question is circular and relies on a presupposition that becomes ridiculous from the subsequent arbitrary rules imposed.

    ;tldr OP’s question is out of scope for ELI5

        Other situations where there is blue light are also out of scope just as the overall harm caused by blue light.

        Your question becomes ‘why wear eyeglasses to filter blue light when there is no blue light?’ The answer is “Science doesn’t say that”.
