Focus on Lenses
Your visit with TWO will involve discussion about your expectations of your new eyewear. With every lens available to Trevor, his recommendations are key to your decision to invest in new and improved vision and quality of life.
Lens designs have evolved with every technological advancement through necessity. Screen time is a contributor to this need for change.
The benefits of protection and comfort are encased in the vast portfolios of lens suppliers: Opticare (Optilux), Zeiss, Hoya, Tokai, Shamir, Essilor, Nikon and Maui Jim are all available to Trevor Williams Optometry and you.
Our professionalism and experience will be shared according to your needs, wants and frame choice.
Single Vision Lenses
Designed for Short-sightedness (Myopia) or Long-Sightedness (Hyperopia).
The prescription power of single vision lenses is identical across the entire lens.
These lenses are used in distance and reading glasses – the two most common vision devices.
With reading glasses, single vision lenses are optimised for vision in the near zone and are great not only for books, but also for reading smaller fonts on a smartphone or tablet.
An optimally fitted pair of distance glasses can help you see nearby and faraway objects clearly once more.
Astigmatism can be corrected with single vision lenses. To achieve this, an additional prescription power is incorporated into the lens, which balances out the astigmatism: this is known as cylinder correction.
Progressive Lenses
Designed for presbyopia.
Progressive lenses have clear benefits compared to bifocal and trifocal lenses. Progressive lenses have a power for the near, intermediate and distance zones – and all of this in a lens with a seamless transition and no dividing line.
The power is smooth from top to bottom and moves from distance to near vision. Progressive lenses enable clear, relaxed vision at all distances and are the perfect choice for correcting myopia, hyperopia and presbyopia. They’re great for reading, working at a computer or with your hands, or for simply gazing into the distance.
Thanks to state-of-the-art production methods with exceptional visual comfort, progressive lenses are precisely fitted to the wearer’s individual needs using a range of factors. They enable not only clear, natural vision, but also fast focusing at all distances and in all directions. It’s an optimum pair of glasses for everyday use – no matter if this is your first pair, or if you want to switch from reading to progressive lenses or have only needed distance lenses until now.
Progressive lenses are also the ideal solution for people with normal vision who are beginning to develop presbyopia, or for people with astigmatism who are developing presbyopia.
Office Lenses
Lenses for clear vision in an office/work environment.
People usually notice the change when they are 40 or older: working at a computer screen and shifting theur gaze – i.e. from the keyboard to the monitor or from the calendar to the telephone – is suddenly more stressful for their eyes. To see clearly at different distances, they often unconsciously assume an uncomfortable posture, e.g. by leaning forward or raising their head. Back and neck pain, or dry/teary eyes are just some of the possible consequences.
Office lenses prevent this type of visual stress: they’re customised for your vision needs while at work and are optimised for all required distances while working at a computer screen.
Reading and progressive lenses, however, are often not the ideal solution because the relevant areas of the lens are not optimised for office work. Reading glasses only enable optimum vision at a short distance – too short for working at the computer or looking at your desk.
With progressive lenses the wearer looks at the monitor through the intermediate area of the lens and must tilt their head upwards to see the screen clearly.
Both types of lenses promote an unnatural posture while sitting, potentially causing muscle tension in your neck, shoulders and back, as well as headaches.
Digital Lenses
Counter Eye-strain from Digital Devices.
Using digital technologies such as smartphones and e-readers demands the utmost from our eyes every single day.
Our eyes are having to become accustomed to a new range of near vision to accommodate the shorter distance at which we hold digital devices compared to a newspaper or a book. And they also require our eyes to constantly switch between different distances. This can lead to headaches and neck strain, and burning or tired eyes, particularly as we get older.
One solution could be distance lenses with special support for your eyes at close range, like Digital Lenses. They are sharply focused on the use of digital devices such as e-readers and smartphones and make it easier to focus in the near and distance ranges.
Driving Lenses
Lenses for a good, glare-free view while driving.
Being able to see well is a prerequisite for safe driving because on the road our eyes are working overtime: we constantly must shift our focus between the street, the GPS, and the rear-view and wing mirrors. Unpleasant weather and adverse light conditions often make it difficult to see. Lenses specially optimised for particular situations faced while driving.
Lens Coating
Lens coatings: While virtually invisible, they’re what make a pair of glasses an effective tool.
Be it a hard layer to protect against scratches or a premium anti-reflective coating that reduces annoying reflections, lens coatings can do a lot to improve your visual comfort, make it easier to clean your glasses and even ensure your lenses last longer.
In particular, plastic lenses with a coating to protect against scratches can make glasses much more resistant to damage.
There are lens coatings that feature a filter for blue UV light and can thus help protect your eyes in any situation, e.g. when you spend hours working at a computer, when driving at night, even smudge and dust resistant.
