So... basically the goggles Maurice from Beauty and the Beast wears.

That's how I normally picture them. 

um ok...yeah I like this

so how would these work on a blind character?

 They wouldn't. The item states "While wearing them, you can see much better than normal..."

Sadly, the blind character cannot see normally. They can't see at all. You could argue that the blind person is picking something up, maybe feeling it out, etc. But these crystal lenses are meant to aid visually, something a blind person cannot benefit from.

So... Basically this is a good item for a Rogue?

Lazy bones. Put in the pictures of the items.

This makes a good trinket or "Lost Thing" in Wild Beyond the Witchlight.

In my game a Player had her "Keen Sight" stolen by a hag, meaning she had to wear thick glasses at all times or be rendered completely blind until she recovered the item.

Other low level magic items I used as PC Lost Things were;

• The ability to talk - Horn of Silent Alarm
• The ability to age - Orb of Time
• Memories of their siblings - Pipe of Remembrance
• Ability to smile - Wand of Smiles

You could rule that 'normal' is sighted vision causing the character to be able to see very well but only up to 1 foot. For a blind character you could rule that while wearing the goggles the crystal lenses vibrate as an echolocation function.
