An aspheric lens, or apshere, is an optic with surfaces defined via a polynomial equation. Aspheres exhibit rotational symmetry around the optical axis, but their radius of curvature alters in line with its distance from the center. Image Credit: PI (Physik Instrumente) LP Aspheric lensesdeliver...

What is an IOL implant? Anintraocular lens (IOL)is a clear, artificial lens an eye doctor implants inside your eye. Most IOLs are used to replace your eye's natural lens if you have cataracts. Doctors can also use IOLs to correct your vision even if you don't have cataracts. This is...
Laser eye surgery is also an alternative way to treat hyperopia, as well as other refractive errors. What type of lens corrects hyperopia? Aspheric high index lenses are used to correct hyperopia. Depending on how strong the prescription is, spherical lenses can also be used to correct hyper...

aA higher index lens is used for very strong prescriptions to minimize the visual appearance and physical weight, as well as to mitigate the distortion that some people experience at the edge of lens of great strength of correction, as our higher index lens are aspheric. 一个更高的索引透镜为...
Be aware, though, that high-index aspheric lenses reflect more light than standard plastic lenses. For the best comfort and appearance, make sure the lenses includeanti-reflective coating, which eliminates distracting lens reflections. High-index aspheric lenses for children should be made of lightwe...
