Prescription Lenses | Eyeglass guide

At Mahdi Opticals we offer a wide variety of lenses and add-ons for your eyeglasses. Our prescription lenses are manufactured by the world’s leading suppliers like Essilor and made with high quality acetate frames. Here’s a brief summary of the type of optical lenses you can find at our store located in Nairobi.


Single Vision Lenses

Single vision glasses are designed to help people who require correction of far-sightedness, near-sightedness or astigmatism. These eyeglasses have just a single optical prescription correction and they distribute focus evenly over the entire surface area of the lens. It is the standard lens choice. Single-vision lenses use one prescription over the whole surface of the lens thus correcting either near, intermediate or distance vision. If you have multiple prescriptions, you would require bifocal or multifocal eyeglasses.


Progressive Lenses

Progressive or varifocal lenses provide a smooth transition from distance correction to near correction, eliminating segment lines and allowing clear vision at all distances, including intermediate, near and far. Progressive lenses are designed to incorporate both near and distance correction thus allowing you to see everything clearly with a single pair. They provide a gradual transition in strength from top to bottom, making it convenient for intermediate viewing distance too. 


It may take a bit of time and practice to adjust to progressive lenses. We advise that you look through the correct part of the lens, i.e the lower part when you’re reading, straight ahead for distance and in-between for computer work. You might also experience some blurriness on the edges but this sensation generally goes away after a few days.



Bifocal Lenses

The primary purpose of glasses bifocals is to provide the optimal balance between distance vision and near vision focusing needs. Eyeglasses with bifocal lenses are available with the reading segments in a variety of shapes and widths including bifocal sunglass options.



Lens Coatings & Filters


  • Anti-scratch coating

Having an anti-scratch coating will make your lenses resistant to the scratches that are liable to occur through everyday usage.


  • Anti-glare coating

Also known as anti-reflective coatings, this coating enhances the way you see the world by allowing more light to pass through the lens while eliminating glare, so you have clear vision on the job, in the classroom, around the house and behind the wheel.
