Two purposes of the eye blinder are

[Silverobama]

I was in a shopping mall and a promoter was selling some eye blinders. I don't know if I call them right so I included the picture.



The promoter said:

The material used to make the eye blinders are pure cotton and two purposes of our them are protecting the eyes from strong lights and assure you a good sleep quality.

Please help me to make the italic sentence natural.

The material used to make the eye blinders are is pure cotton and two purposes of our them are they serve to protecting the your eyes from strong lights and assure you of a good sleep quality.

I’ve only ever heard them called eye masks or sleep masks.

 

[Silverobama]

I’ve only ever heard them called eye masks or sleep masks.

The material used to make the eye masks/sleep masks are pure cotton and two purposes of them are protecting the eyes from strong lights and assure you a good sleep quality.

Is this version natural and grammatical?

You have repeated one serious mistake that tedmc pointed out and ignored his other improvements.
