Abstract:
1. A method of treating an optical lens comprising: obtaining an optical lens to be treated; a placing the lens in an optical lens holder comprising a support and a first and a second arm defining a lens holder general plane, the first and second arms being relatively movable with regard to each other and each arm having spaced apart first and second end portions and an intermediate portion, the arms being mounted on the support through their first end portions and the second end portions of each arm adapted to accommodate an optical lens during use, whereby an optical lens can be maintained within the first and second arms with its optical axis orthogonal to the general plane of the lens holder through at least one contact point between the lens periphery and each of the first and second arms, wherein at least the second end portion of each arm comprises a material having a dielectric constant at 1 MHz equal to or higher than the dielectric constant of the optical lens material and greater than or equal to 3.0, and a specific heat (kJ kg treating the lens while it is in the holder, said treatment comprising a corona discharge treatment.
