I am an optometrist and wearing phot solar glass has benefits but it needs to be prescribed for you from clinic. sunglasses have unwanted effects on your vision

Blue light filters are useless I mean they filter blue light, but it's not the blue light that is hurting you It's that you stare at ur pc or phone for a long time Notice that u would also have pain reading books for a long time Just don't use ur phone or pc on dark place, thats another science And the itching or pain or redness of ur eyes might be ur allergy to uv ray(sun) if thats the case solar lens might be a good choice Sunglasses might be best, but u don't wanna look ይርዳው ጤና right? :)
