| abstract |
An ophthalmic lens and a method for providing a thin coating thereon is disclosed. The coatings render the surfaces of the devices resistant to abrasion and have an SEB abrasion resistance of at least 20 psi. They are optically clear, aberration-free, and provide essentially exactly an optical surface having the desired surface configuration. The coating compositions employed contain reactive ethylenically unsaturated groups and are applied to a mold face and partially reacted. The coated mold is then used to cast the ophthalmic device. |
