DUCOSunglasses for Men Carbon Fiber Temples with Rectangular Polarized Metal Frame Sunglasses DC8206

Do these sunglasses fit a skinny head or would they be a bit loose ?

Can i watch tv in these without the tv screen turning blue? I ask because i suffer with migraines and watch tv with polarized sunglasses on!

Can Duco confirm these are UV 400 protected?

what is the arm length please or temple length is it ? These said 155 is that correct as 145 is to short for me .. many thanks
