I’m not much of a lunar observer but enjoy observing it when it’s less than half full (not too bright) and like viewing along the terminator (the division between the dark and light side of the moon). When it’s full the detail gets a bit harder to discern. Mars probably is a blurry blob at present (haven’t checked lately) but Jupiter should show some bands. Play with focus and a higher power eyepiece (10mm should be fine) and make sure you’ve let the scope cool down (around 30 minutes or so). See if you can find a nice adjustable chair to observe with (an observing chair is well worth the investment). It will make the process a bit more relaxing and should assist with relaxing the eyes :-) There’s lots of trial and error to start with (identifying stars, getting used to setting things up, trying different eyepieces etc.) so aim to keep it simple and roll with the punches.
