In a highly competitive world, the need for speed takes a toll not only on the body, but also our eyes. Many fall prey, to a faster aging process of the eyes hence the requirement to get a multi-focal lens is more of a “when” rather than an “if” scenario.
Presbyopia is an eye condition that creates the need for a multi-focal correction much like myopia (nearsightedness) and hyperopia (farsightedness), presbyopia involves the inability of the eye’s lens to focus correctly. More commonly found among those aged 40 to 45, when presbyopia occurs, the eye has trouble focusing on up-close objects, creating a need for vision correction at reading distance.
People with presbyopia, often get by with over-the-counter “readers” that provide up-close correction, however those with other eye conditions in addition to presbyopia, need to get a prescription for bifocals, trifocals or progressive lenses. One needs to visit an optometrist or ophthalmologist to see which option is best suited for your need.
Bifocal: Provides two areas of correction, for near and distance.
Trifocal: Three areas of correction—near, distance and an intermediate middle zone for specific activities.
Progressive: A gradual progression lens that offers the widest range of correction. This lens is shaped to allow correction at nearly any distance, based on which part of the lens is looked through
