Dual Camera for iPhone 6 ?

I have a regular iPhone 6. But i want a dual camera lens ( housing) so I tried get a iPhone 8 Plus housing for a 6 or even a iPhone 7 Plus housing because I like their lenses. But the dual lens housing ( which I like ) only for the plus 6 . Like all the regular iPhone 6 housing got no dual lenses they have the circle type

Is there any way I can get a dual lens ( iPhone 7 Plus or iPhone 8 Plus ) housing for the regular iPhone 6 ?

Am I blocked? Can he see my msgs?

My guy friend and I had a bad fight but he said everything was fine. We both have iPhones but recently when I text him it turns from blue to green. Also when I call it goes straight to voicemail (no rings or nothing). So am I blocked? And if so is he receiving any of my green text messages or voicemails?

Do iphones cause brain damage&ear ringing?

Everytime and recently.
i'm using my iphone and i have a high pitched ringing noise in my ear drum.
i sometimes have pink eye or blood shot eyes.
I get a headache feeling my head is frying or about to burst.
i noticed the less i'm on, the less i feel pain in my head.
i usually relly on it cause i don't have a computer to use at closest local library
