Contact lens cleaning compositions with particles of variable hardness and processes of use |
摘要 |
Compositions and methods for treating a contact lens are disclosed. In one embodiment, the composition comprises an ophthalmically acceptable liquid aqueous medium and a plurality of particles which possess a hardness gradient. The hardness gradient of the particles is due to the particles having a relatively inelastic, water-impermeable core and a soft, water-permeable outer layer surrounding the core. The particles afford both high specific pressure on a contact lens surface and textural softness, which diminishes surface abrasion.
