Contact lenses definitely possess more advantages than the standard eyeglasses when it comes to convenience and aesthetic appearance. These lenses are often used to correct refractive errors like Astigmatism, Myopia (nearsightedness), Presbyopia, and Hyperopia (farsightedness). Refractive errors are either inborn or acquired, but Presbyopia comes with aging and will require the use of multifocal contact lenses.
Multi-focal contact lenses are used to correct Presbyopia. The condition occurs when the aging lenses lose their elasticity and thus cannot correctly focus the light on the affected person’s retina. Impaired focus on the retina secondary to faulty lens accommodation will result to overlapping myopia and hyperopia. The condition is usually corrected with the use of bifocal eyeglasses, however, with contact lenses becoming the norm, multi- focal lenses also evolved to cater to individuals who wish for the benefits and conveniences contact lenses offer.
Contact lenses used by patients with Presbyopia work in the same way the bifocal eyeglasses does. It grants the wearer multiple levels of corrective power which may be classified as simultaneous, translating, and the recent hybrid multifocal contact lenses. Simultaneous lenses have areas that differ in corrective power and allow the eyes to focus on far and near objects all at once. Translating lenses, on the other hand, have two distinct areas that functions like the regular bifocal glasses. Translating lenses are subdivided into two parts, the bottom half is used focusing on close objects whereas the upper half is for far objects, it is available only in hard contact lenses. The hybrid multi- focal lenses sport a soft rim and a hard inner section and boasts of providing the wearer with crisp vision without an extensive adjustment time.
The market offers all of the aforementioned multi-focal contact lenses. For safety reasons and to prevent inconveniences, it is best to seek professional advice on what will work best for you and your lifestyle that fits your budget.
