Smart glasses
My idea is to create smart glasses. The eyeglasses will automatically adapt the wearer's head position, adjusting their focus as needed.
There will be an LCD-like layer in the glass that can change structure when excited by an electrical current, adjusting the focus. The frames will have a built in accelerometer that can detect movement, such as lowering the head to read.
What is more, the glasses are supposed to have both manual and automatic modes.
