Head mounted display and method

1. A head mounted display for a user that uses a display screen to produce images comprising:

a frame having a first face which holds the display screen, a second face which holds a first reflecting surface; a third face which holds a pair of lenses; a fourth face which holds a second reflecting surface and a fifth face which is flat having only two eyeholes and a nose hole that is positioned on the nose of the user and is perpendicular to the third face, with the eyeholes aligned with the eye of the user, the light emitted from the display screen is reflected by the first reflecting surface to the pair of lenses, which focuses the light as it passes through the lenses to the second reflecting surface, which reflects the focused light to the eyes of the user through the eyeholes, the pair of lenses have their optical centers biased away from their physical centers, the first face disposed above the fifth face so the display screen is above the user's eyes, the first, second, third, fourth and fifth faces can fold onto themselves into a flat shape, the fourth face directly connected with the fifth face; and

a strap which attaches to the frame and fits about the user's head to hold the frame to the user's head.

a frame having a first face which holds the display screen, a second face which holds a first reflecting surface; a third face which holds a pair of lenses; a fourth face which holds a second reflecting surface and a fifth face which is flat having only two eyeholes and a nose hole that is positioned on the nose of the user and is perpendicular to the third face, with the eyeholes aligned with eyes of the user, the light emitted from the display screen is reflected by the first reflecting surface to the pair of lenses, which focuses the light as it passes through the lenses to the second reflecting surface, which reflects the focused light to the eyes of the user through the eyeholes, the pair of lenses always maintain for any field of view two separate non-overlapping images for the user's eyes, the first face disposed above the fifth face so the display screen is above the user's eyes, the first, second, third, fourth and fifth faces can fold onto themselves into a flat shape, the fourth face directly connected with the fifth face; and

a strap which attaches to the frame and fits about the user's head to hold the frame to the user's head.

3. A method for viewing images by a user comprising the steps of:

placing a head mounted display on a head of the user, the head mounted display having a frame having a first face which holds a display screen, a second face which holds a first reflecting surface; a third face which holds a pair of lenses; a fourth face which holds a second reflecting surface and a fifth face which is flat having only two eyeholes and a nose hole that is positioned on the nose of the user and is perpendicular to the third face, with the eyeholes aligned with the eye of the user, the head mounted display having a strap which attaches to the frame and fits about the user's head to hold the frame to the user's head, the first face disposed above the fifth face so the display screen is above the user's eyes, the first, second, third, fourth and fifth faces can fold onto themselves into a flat shape, the fourth face directly connected with the fifth face; and

emitting light from the display screen which is reflected by the first reflecting surface to the pair of lenses, which Focuses the light as it passes through the lenses to the second reflecting surface, which reflects the focused light to the eyes of the user through the eyeholes, the pair of lenses always maintains for any field of view two separate non-overlapping images for the user's eyes.
