Blue Light Blocking Lenses

Devices like smartphones, tablets and computers monitors are an integral part of the modern day world. It’s been shown that these devices cause eyestrain with extended use, and it’s largely due to the amount of blue light emitted by these screens. Blue light can cause eyestrain and affect sleeping patterns, which in turn can affect work performance and overall well being.  At Zoom Optics, we can protect your eyes from the harmful effects of blue light with our Blue Light Blocking Lenses. Even if you don’t need a prescription, we can supply protective Blue Light Blocking lenses to help your eyes throughout the day.

Single vision & Bi-focal lenses

Single vision lenses are the most commonly prescribed lenses; these have the same focal power over the whole lens. They’re set to be used for one viewing distance only, and correct the wearer’s vision either up close or at long distances for an affordable yet perfectly serviceable option.

Bi-focals are a versatile option that are designed to offer two fields of vision. They have no correction for the intermediate distance, though. The lenses are sectioned into two distinct parts. The larger top part of the lens allows the wearer to see distant objects, whilst a small part of the bottom section allows the wearer to see objects in close distance. Generally, the wearer looks up when focussing on points further away, and down when focussing on reading material.


These revolutionary lenses allow the wearer to see both close-up and far off objects seamlessly. Instead of just having two lens powers like bifocals, multifocals lenses allow a progression of lens powers, giving focus at all distances. With a continuous, gradual change from distance to intermediate to near vision, you get the best of both worlds, from the one set of lenses. Zoom Optics has access to  the latest multifocal lens designs, allowing more natural vision and aiding easier adaptation, even for those who have had trouble with multifocals in the past. They may take a bit of getting used to, but once you’ve had a bit of experience wearing these innovative lens types, you’ll wonder how you did without them.

Lens Materials

Standard Plastic

Compared to glass lenses, plastic lenses are more impact-resistant and lighter than glass lenses, making them the standard in the optical industry. UV protection and tinting can also be added to the lens to further meet your needs. Because of their cost-effective nature, safety and versatility, plastic lenses are a popular and attractive option.


Polycarbonate is one of the strongest, safest materials around, and lenses made of this material are very popular for several reasons. Because of their innovative construction, polycarbonate lenses are up to 27% lighter than ordinary plastic lenses, allowing the wearer a higher degree of comfort. They’re also a lot thinner than other lenses; making them less noticeable when fitted to a wearer’s frames, as well as being 10 times more impact-resistant than ordinary plastic lenses, reducing the risk of eye injury. Need protection against the elements? These lenses block 100% of UV rays for a comprehensive option.


Hi-Index lenses are perfect for those with higher strength prescriptions. Available in a number of indexes, these lenses can be made thinner, lighter and flatter than was previously possible for a convenient option. The lenses are compressed, which allows for better optical viewing without compromising their aesthetics. Previously, people with a high prescription would have to suffer through the discomfort of wearing heavy, bulky lenses, but Hi-Index lenses feel lighter on the nose. The flatter shape also prevents distortion of images, making them a great option for many people.

Lens Options

Multicoats & Antiglare Coatings

All lenses should really come with multicoats & antiglare coatings. These coatings allow more light to focus into the eye and give a sharper, clearer image and reduce eyestrain. All camera lenses come multicoated for sharper images, why not expect the same from your glasses?


A super convenient options which gives your vision correction as well as glare & UV protection all in the one set of lenses. These lenses change to dark when outside and crystal clear when back inside after only a few minutes.

Sunglass Tints & Polarised Lenses

Zoom Optics can customise most sunglass frames to include your prescription lenses. We can also do polarised lenses in your prescription into your favourite sunglass frame to give you maximum glare protection so that you can enjoy all your outdoor activities naturally and comfortably.
