An ophthalmic lens is any type of lens specifically designed to correct, protect, or enhance human vision. This includes lenses found in prescription eyeglasses, contact lenses, and certain surgical intraocular lenses (IOLs) implanted during cataract surgery.
read more about ophthalmic lens ...An ophthalmic lens corrects vision by precisely bending (refracting) incoming light onto the retina. These contact lenses are individually surfaced to correct specific refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, allowing the wearer to achieve clear sight.
Yes. An ophthalmic lens is subject to rigorous quality control standards, including international ISO standards, to guarantee that the optical power, center thickness, and surface quality meet the specified prescription precisely. These standards are important for patient safety and visual performance.
Management depends on the type:
Eyeglass lenses: Should be cleaned with appropriate solutions and microfiber cloths to prevent scratches and maintain optical clarity.
Ophthalmic lenses are provided by optometrists and ophthalmologists. For contact lenses specifically, Lens.com provides a substantial selection of all major lens brands, enabling you to order the exact lenses specified in your prescription for convenient delivery.
Are contact lenses ophthalmic lenses?
Yes. Contact lenses are highly specialized, thin ophthalmic lenses that sit directly on the eye.
What is the difference between a lens and a prism?
A lens corrects refractive error, while a prism is used to shift the image to help align two eyes that are not working together.
Can I use the same prescription for contacts and glasses?
No. Contact lenses sit directly on the eye, so the prescription power must be adjusted from the glasses prescription.
