Types of Lenses

At Eglinton Eyecare we believe that once you’ve found the perfect frame there’s absolutely no room for compromise when choosing the best lenses to put into it! After all it’s the lenses which make sure you have a perfect uninterrupted view of the world.

Whether you’re choosing the very latest technology in a varifocal or a more basic single vision lens our fully trained dispensing team will guide you through the process of choosing the lenses and coatings which best suit your prescription, your lifestyle and your frames. Over the last few years we’ve invested in state of the art technology to make these decisions as easy as possible!

When we discuss the lens options which best suit your needs, we will demonstrate to you the benefits of each lens/treatment using our Vision Consultant app on the ipad. We also know that no two people use their glasses the same way, that’s why we use Hoya’s “Visureal” iPad technology to dispense your lenses, ensuring that they are personalized to give you the best possible vision.

Our dispensing team will guide you through the process of choosing the perfect combination of frame and lenses to ensure your finished glasses look and feel their absolute best. We will use the latest technology from Hoya to demonstrate to you how we can reduce the weight and thickness of your lenses (by up to 50%), ensuring that you enjoy maximum comfort when wearing your glasses.

Single Vision lenses are the most basic of all lenses. They’re generally are the lenses of choice for most under-40 year olds, when a single vision lens will allow you to see well at most distances.

Varifocal Lenses

As we mature, so do our eyes. Basic single vision lenses then only allow us to see at one particular distance: generally far away, near or at an intermediate (e.g. computer screen) distance. When you reach this stage an additional prescription will be required to enable you see at different distances. Nowadays the most common way to correct this is with a varifocal lens. Varifocal lenses allow us to see well across all distances. The design of variocal lenses has improved dramatically over the last few years, allowing us a much wider uninterrupted field of view. Utilising Hoya’s Visureal system we can help you to experience truly hi-definition vision!

“Freeform” Lenses

These are at the cutting edge of lens design, starting with a “puck” of plastic material your lenses are individually ground down with diamond-tipped cutting equipment to ensure you get the widest possible field of view and the most natural vision from your glasses. To ensure that your lenses are truly tailor-made we use cutting edge technology using Hoya’s Visureal iPad app. No two patients are the same and this ground-breaking piece of equipment enables us to take the extra measurements required at the click of a button to ensure your glasses are perfectly tailored for you.


These lenses have a small reading ‘button’ at the bottom of the lens. Their uses are more limited to only allowing us to see at two specific distances, generally far away and reading. They allow a wide field of view for their specific tasks.

Bifocals however have a visible line on the lens which can cause a ‘jump’ when your eye passes over it. Bifocals are not suitable for intermediate tasks (e.g. seeing a computer) which usually mean that a varifocal is the lens of choice in preference to a bifocal for anyone who uses a computer.

Occupational Lenses

Occupational lenses are designed to act as “enhanced” reading lenses – allowing you to view close up work (typically 30/50cm) as well as computer screens and presentations screens or across the room, up to 4m away. This increased flexibility offers a fantastic alternative to single vision reading lenses which only offer one specific working distance.
