Contact lenses for correcting severe spherical aberration |
摘要 |
The present invention is related to a contact lens for correcting severe spherical aberration. The contact lens of the invention comprises an anterior surface having a first optical zone and an opposite posterior surface having a second optical zone. The first optical zone is defined by a mathematical function including a conic term and at least one 4<SUP>th </SUP>or higher order mathematic term. The first optical zone, in combination with the second optical zone, provides a power profile in which the optical power of the lens decreases outwardly from the optical axis to the outer periphery such that the optical power at a 6 mm diameter is from about 1 to 5 diopters smaller than a manifest refractive power for an eye. The present invention also provides a series of contact lenses and a method for making contact lenses of the invention.
