Yeah I agree with you. It’s one thing to say the school can’t promote a religious creed to the pupils, it is another to limit self-expression of dress when it doesn’t impact other students

I like this thought because my personal experience is wearing regular perscription glasses and staring at a screen 10-14 hours every day with no eye strain or headaches. My sister loves and swears by the blue light filtering (but doesn’t wear glasses otherwise)
