Spectacle Lenses are available in various types but they can be broadly classified into 3 types:
Single Vision Lenses
Varifocal / Multifocal Lenses
Single Vision Lenses:
Single vision has the same optical focal point or correction over the entire area of lens.
These are basic clear lenses without any coatings, however you can opt to have a variety coatings added.
These are standard index lenses which are just made flat to look cosmetically neat. These spectacle lenses are not thin just flat convex lenses, and come with Multi-Antireflection Coatings.
Advanced optical design technology allows aspheric eyeglass lenses to be made with flatter curves than conventional lenses, giving them a slimmer, more attractive profile. Conventional lenses have a front surface that is spherical, meaning it has the same curve across it's entire surface, much like a baseball. Aspheric lenses, on the other hand, have a more complex front surface that gradually changes in curvature from the centre of the lens out to the edge.
Double Aspheric / Bi-Aspheric:
By incorporating the latest double aspheric technology into DAS, the manufacturer is able to achieve the best optical performance amongst stock lenses available today. The double aspheric design enables a further reduction in unwanted astigmatism compared to aspheric design.
In today's world ones eyes are constantly focusing on computer screens, tablets and mobile phones. Focusing on close objects puts a strain on the eyes and especially when combined with long work hours this prolonged accommodative effort often leads to tiredness, headaches and blurry vision. Easy is a new generation of advanced prescription lenses that give relief to hard working eyes, in addition to correcting their vision.
Bifocal lenses contain two different prescriptions in the same lens. The primary purpose of bifocals is to provide the optimal balance between distance vision and near vision focusing needs. These lenses are available with the reading segments in a variety of shapes and widths including transition and sunglass options.
Varifocal / Multifocal
Progressive addition lenses, or multifocal lenses, are prescription lenses used to correct Presbyopia instead of bifocals and reading glasses. They are characterized by a gradient of increasing lens power, added to the wearer's correction for the other refractive errors. The gradient starts at the wearer's distance prescription at the top of the lens and reaches a maximum addition power, or the full reading addition, at the bottom of the lens. ‘We specialise in tailor made Freeform Varifocal Lenses’.
Office / Desktop Lenses
An office progressive ensures a smooth transition from mid to near distance vision. These lenses are designed to match user’s requirements from clear, sharp vision for the computer to reading a book.
Anti-reflective coating (also called "AR coating" or "anti-glare coating") improves vision, reduces eye strain
and makes your spectacles look more attractive. (www.allaboutvision.com)
Hard Multi Coating:
Achromatic coating delivers boundless vision. The revolutionary coating was developed for you through use of the High Graduation System (HGS).
HGS is an innovative calculation system for the design of multiple layers in a coating. It includes the arrangement and precision of multiple anti-reflection layers and the widening over the spectral range of visible light from 380 nm to 750 nm.
Honeycomb lenses utilise the ‘pin-hole effect’ to sharpen vision, and reduce eye strain and glare. They are ideal for Driving, Computer use and everyday wear. Pinholes work by letting into the eye only light rays entering at the centre of the pupil, focusing the image on the retina at the back of the eye.
BlueShield provides protection against the harmful blue rays in the light.
What is Blue Light?
Blue light itself is nothing new; it is as old as the sky above us. It has been present in natural light and in artificial light in varying concentrations. Blue light is visible light which radiates at a short wavelength placing it at one end of the visible light spectrum with a range of approximately 380-500 nanometers. Blue-violet light (380-455 nm) is very close in wavelength to ultraviolet light (10-380 nm), a well-known hazard to our eyes and our health if we are exposed to it in repeated, large doses. Now recent studies have revealed that blue-violet light can cause retinal cell death, contribute to cataract formation and accelerate retinal damage in those who have macular degeneration.
Internal MAR Coatings:
They also known as back surfaced anti-glare coatings used for Sunglasses to reduce ghost images.
Mirror coating on sunglasses decreases the amount of light passing through the tinted lenses and into your eyes. Your eyes will feel more comfortable and have less strain than if you were wearing tinted lenses without the flash coating.

Transitions ® Signature™ VII lenses replace Transitions® VI lenses as the most
balanced everyday lenses yet. They are more responsive in most situations. They
provide the ideal combination of darkness, fast fade back speed and indoor clarity.
Offering superior darkness outdoors, even in hot temperature, Transitions ®
XTRActive™ lenses are ideal for wearers who spend much of their day in bright,
sunny conditions. Indoors, they have a comfortable hint of tint. Specifically designed
to be extra dark outdoors, they also moderately activate inside the car.
FashionChrome is our stunning new stock range of flash mirror coatings on top of Transitions
XTRActive lenses. Available colours include Red Sunrise, Rose Gold, Mystic Violet, Silver Sky,
Royal Blue and Sea Green. FashionChrome combines the benefits of Transitions technology,
protecting eyes from the brightest sun and harsh artificial light, with thelatest Italian fashion.
Be cool, be fashion with FashionChrome!
Drivewear® lenses provide glare protection through polarization and enhance and protect vision through photochromics which respond to both visible and UV light. By combining the strengths of two of the most important technologies in eyewear today we have developed the lens of tomorrow, Drivewear®.
Tinted for Prescription Sunglasses:
We offer a full range of tints. You can choose from filters, solid or graduated single colour tints or even bi-colour tints. We offer polarized lenses which align light rays from the sun, giving you a crystal clear view at all times. We are also able to provide a variety of mirror coatings, offering up to 100% UV protection.
We specialize in all kind of lenses, from single vision to bifocals to progressive lenses.
Sports wrapped frames:
These days many different demographics enjoy sports. This is true of all ages, both young and old. Two-thirds of the population participate in sporting activities of which at least 60% of them require vision correction, and an excellent cosmetic look is required along with great corrective vision. Today sunglasses are a necessity for all. Most Rx sport lenses are compromised with a low base curve and inferior optical properties. These special Lenses are surfaced to accommodate the curvature of the frames to improve the optical properties and making them cosmetically appealing.
Polarised & Polarised Plus:
Light usually scatters in all directions; but when it's reflected from flat surfaces, it tends to become polarized — meaning it travels in a more uniform (usually horizontal) direction. This creates an annoying and sometimes dangerous intensity of reflected light that causes glare and reduces visibility. Polarized lenses contain a special filter that blocks this type of intense reflected light, reducing glare.
Polarized lenses enhance the most important functions of prescription eyewear: improvement of visual acuity and the ability to block blinding horizontal glare. No other lenses or treatments can achieve this result.
