It works by gently pressing on the cornea, reducing its curvature, and thereby refocusing the light directly on to the retina to restore it to the shape of someone with normal vision. It is like reshaping the eye back to the normal state.
The reshaping is temporary, however, because the cornea will gradually spring back to its original shape, so the lenses must be worn every night.
To get the right pressure, the curvature of the eye is measured – a procedure known as corneal topography. The lenses are then shaped to these contours, so pressure is applied evenly over the front of the eye.
This technique, known as orthokeratology. It’s thought the Chinese slept with small weights or sandbags on their eyelids to reduce short-sightedness.
It was found the new generation of overnight lenses can improve vision by around 70 per cent after one night, often correcting sight fully within a week.
