If you have two distinct prescriptions, bifocal glasses are worth acquiring since they can fit both in one lens, allowing you to effortlessly transition between the two.
Wearers can, for example, spend the most of their time gazing through the distance component of their lens, then rapidly switch to near-sighted activities like gazing at their phone or a computer screen by staring through the bottom section of their lens. This is more convenient than continually switching between two pairs of glasses.
The bottom half of a bifocal lens, which accommodates near vision, can be designed in a variety of ways. The form of this part of the lens changes based on the demands of the wearer. A half-moon, circle, narrow rectangle, or the whole bottom half of the lens are all possible shapes.
Varifocal lenses combine three prescriptions, generally far vision, intermediate vision, and close vision. Bifocal lenses combine two prescriptions, but varifocal lenses include three prescriptions.
Varifocals, unlike bifocals, easily transition between prescriptions with no discernible line between them. As a result, they appear more like regular spectacles in Bangladesh, whereas bifocal glasses are more noticeable.
It gets more difficult to read or focus on stuff up close as we become older. Presbyopia is a condition that occurs as people become older and is a natural component of the aging process. You may be experiencing presbyopia if you find it difficult to use a phone or read a book up close and must hold objects far away to see them well.
It may be time to acquire bifocal or varifocal spectacles if you currently wear glasses and notice presbyopia. If you don’t currently use glasses, single-vision lenses may be all you need. Our varifocal lenses are accessible to see on the prescription journey, but if you’d like to learn more about our bifocal alternatives, make an appointment with one of the recognized opticians in Bangladesh to discuss your alternatives.
