What is the opinion of Reddit about the
CALIDAKA Blue Light Blocking Lens,Replaceable Anti Blue Light Blocking Eyeglasses Lens with Frame Protection Accessories for Oculus Quest VR Headset?

Anything like that with such a curved surface is hard to get on and have no bubbles or other issues. You probably need to wait for a third party one to come out. Currently your other options are glasses spacers that are just thick rings around the lenses or you could order the prescription type lenses or blue light blockers to add a second layer of glass in between as a safe space. These ones aren’t too expensive https://www.amazon.com/dp/B08JLFCBKJ/ref=cm_sw_r_cp_apa_i_xu3.Fb1YVKH6J?_encoding=UTF8&psc=1
