Patent ID: 8434870

Claim:
A method of simulating an optical effect of an optical lens for a potential wearer, the method comprising: using a first camera to take a first image of a scene through a first optical lens, the first optical lens having optical characteristics according to a first ophthalmic lens design, the first camera being provided with optics arranged to simulate the optical characteristics of a human eye; and transferring the first image to a display device so as to display the first image on the display device for viewing by the potential wearer enabling the potential wearer to visualise the optical effects of the first optical lens on his viewing ability, replacing the first optical lens with a further optical lens having optical characteristics according to a further ophthalmic lens design, different to the first ophthalmic lens design; taking a further image of the scene using the first camera through the further optical lens; and transferring the further image to the display device so as to display the further image on the display device for viewing by the potential wearer so that the potential wearer can compare the optical effects provided by the first optical lens with the optical effects provided by the further optical lens.
