Optical Frames are the part of a pair of glasses that holds prescription lenses in the proper position. These are frames in which opticians can mount different types of prescription lenses. They are best suited for a particular visual requirement. Optical Frames, when worn with corrective lenses, can help sharpen your vision for different activities like reading, driving or computer use.
Uses of Optical Frames
1) Vision problems: The lenses in optical Frames focus light rays properly on the retina in the eye.
2) Distance lenses: For fitting lenses suited for distance correction.
3) Reading lenses: Provides vision correction for people suffering from presbyopia or long sightedness. This correction is usually for reading or computer use.
4) Multifocal lenses: These are lenses that provide both near and distant correction.
5) Protection: Optical frames protect against flying debris for construction workers, lab technicians or welders.
