Your guide to lenses
Even more important than the frame you select and how good it looks, are the lenses.
When choosing lenses you’ll need to consider things such as your job, hobbies, sports and overall lifestyle. Of course your prescription, budget and frame will also help determine the lens you select.
Our dispensing opticians or optical assistants will explain the best options for you.
Single vision lenses: Have only one power across the whole lens. This is the most common lens option for people under 45. As you get older, and for people with certain eye conditions, one lens power won’t allow you to see clearly at all distances. You’ll find that glasses good for driving are not any help for reading! If this is the case you can choose either bifocal or progressive lenses.
Progressive lenses: Give’s you clear vision at all distances from far away through to near reading, without any sudden changes in power. This means your computer screen will also be clear.
occupational progressive: Will give you clear vision for just reading and at the computer screen.
Bifocal lenses: Give’s you clear vision at distance and close up, with an obvious line on the lens dividing the 2 powers.
Thinner and lighter – today’s plastic lenses can be made thinner and lighter by using special materials that enable us to make even the strongest of prescriptions more comfortable to wear. Your fashion frames will look great with these thinner lenses.
No reflections – An anti-reflective coating on your lenses means you can see more clearly, especially when driving at night and sitting at the computer. People looking at you will see your eyes and not the reflections of what’s around you. Plus, new technology means the coatings are easier to clean than ever before.
Transitions (lenses that go dark in the bright light) – Transition lenses provide a comfort lens for anyone who spends a lot of time outside or just finds bright light makes their vision uncomfortable. They quickly darken in bright light and return to clear when you return inside – all automatically. This lens is very convenient but it won’t darken very much behind the car windscreen so is not the best sunglass for driving.
Polarised lenses – for the ultimate in sun and glare protection we recommend a polarised lens. Unlike transitions they stay dark all the time and are not only great for driving and fishing, but also for anyone out and about on the water or in the snow. If you’re light sensitive in any situation these lenses are a must.
We have fashion sunglass frames that can be glazed to your prescription, or if you prefer the sporty look, frames that have optical inserts. You don’t have to go without sunglasses just because you require a prescription.
Of course all our plastic lenses provide UV protection to help prevent long term damage to your eyes and possible cataracts.
Modern acrylic lenses are far safer than the tempered glass lenses that people used to wear. Materials such as polycarbonate and Trivex are hugely impact resistant and provide the ultimate in safety for sports people, children and those in occupations where eye safety could be an issue. People with poor vision in one eye should insist on safety lens materials.
Lens technology is continually changing and our staff keep up to date with the latest advances. As an independent optometry practice we can choose the ideal lenses for you and are not restricted to any particular brand or design. However we especially support the Nikon family of lenses. Nikon lenses take the world’s greatest pictures and the same technology is available in their spectacle lenses.
