Hybrid multifocal contact lenses |
摘要 |
The invention provides a multifocal ophthalmic lens that is a hybrid lens in that it combines both soft lens material and rigid lens material. The lens is more comfortable to wear than a rigid lens and yet it provides correction for astigmatism without the need for the addition of cylinder power.
