Detriment or Styles

Bear a physical resemblance to wearing a contact lens. It really looks like though, but it's not. It only resembles to lens maybe because of the vividness of the lights of the camera itself.  It appears like wearing a gray thin curved glass designed to fit over it to correct vision. But I'd rather choose wearing an eyeglass instead of this thing. Having a fear that it might make my eyes hurt or bleed, heck I'm filled with fear when it talks about eyes matters. 

I have so many apprehensions and feeling worries about this idea. Especially when sometimes being forgetful, I'm afraid I may not able to remove it when I go to bed and fall asleep. And all of a sudden, I abruptly rub it with my fingers, then that will cause my eyes to get hurt and worst will cause to bleed. Sufferings will be present.
