Recently, I observed that the mirrors in most barbershops (in India) are placed at a large distance away from the customers (at least three feet). Barbers usually ask myopic customers to remove their glasses during the haircut. This creates a problem because the image is made at least six feet away from cusomers. Most myopic people are unable to see things clearly at such a distance without their glasses. 
A possible solution is to place the shelves sideways and hang the mirrors on walls(the mirror should not be more than a feet away from the customer). Placing the shelves sideways is a potential solution because mirrors are placed three feet away just to accomodate the shelves. Barbers should not face any problem with this and the myopic customers will only be happier.
