Claims55
An anti-static, anti-reflection, transparent coating for a transparent ophthalmic lens, the coating including at least one electrically conductive layer, wherein the sheet resistance of the coating is between about 107 ohm/square to about 1010 ohm/square and the luminous transparency of the ophthalmic lens, when coated on both sides with the coating, is greater than about 95% and the luminous absorption due to the coating is less than about 1%.
An ophthalmic lens having an anti-static, anti-reflection transparent coating, the coating including at least one electrically conductive layer, wherein the sheet resistance of the coating is between about 107 ohm/square to about 1010 ohm/square and the luminous transparency of the ophthalmic lens, when coated on both sides with the coating, is greater than about 95% and the luminous absorption due to the coating is less than about 1%.
A method of fabricating a transparent ophthalmic lens, the method including the steps of:
- providing a transparent ophthalmic lens;
- and
- forming on a surface of the ophthalmic lens an anti-static, anti-reflection transparent coating having at least one electrically conductive layer, such that the sheet resistance of the coating is between about 107 ohm/square to about 1010 ohm/square and the luminous transparency of the ophthalmic lens, when coated on both sides with the coating, is greater than about 95% and the luminous absorption due to the coating is less than about 1%.
