Light entering the eye needs to be focused accurately on the retina to permit sharp vision. There are two main structures in the eye that is responsible to focus the light accurately: the cornea at the front of the eye, and the natural lens, situated behind the colour of the eye. Some people need the help of spectacles or contact lenses to improve and sharpen their vision, but there is an alternative.

As an ophthalmologist, Dr Frikkie Hartog offers two corrective eye surgeries to eradicate the need for spectacles entirely.
