When it comes to eye health, most people know that eye lenses are an important part of keeping your vision clear. But what do you need to know about eye lenses?
What should I know about this?
Here is a quick guide:
There are two main types of lenses: corrective and non-corrective. Corrective lenses are used to improve vision, while non-corrective lenses are used for protection or cosmetic purposes.
Corrective lenses can be further divided into two categories: single vision and multifocal. Single vision lenses correct for one type of refractive error, such as nearsightedness or farsightedness. Multifocal lenses correct for multiple types of refractive errors, allowing you to see both near and far objects clearly.
Non-corrective lenses include contact lenses and sunglasses. Contact lenses are usually worn to improve appearance, but they can also be used for therapeutic purposes.
