Prescription Lenses &
Lens Technology
The frame gets noticed. The lenses do the work.
At Oculus Dexter, we take the same considered approach to your lenses as we do to your eye care and eyewear. We combine detailed measurements, experienced dispensing and premium lens technology to recommend lenses around how you actually see, work, drive and live.
We fit mostly Rodenstock lenses and use advanced DNEye® and digital centration technology where it adds value - but our starting point is always the same: the best lens for the patient, not the most expensive lens on the list.
We discuss personalised lenses as part of our → Eye Examinations.
The best lens for you
There is no single “best” spectacle lens for everyone. Your prescription is only part of the decision. The frame you choose, how it sits, the distances you use most, your work, screen time, driving, sport and sensitivity to light can all change what will work best.
We usually begin with the lens we believe will give you the best optical result for your needs, then explain the options and trade-offs clearly. If a simpler solution makes more sense for how you will use the glasses - or for your budget - we will tell you that too.
The aim is to make sure the lens you buy is the right one.
From measurements to finished glasses
We start with your prescription, symptoms and the way you use your glasses - from work and screens to driving, reading, sport and time outdoors. Your previous glasses can also tell us a lot about what has and has not worked for you - make sure you bring them along!
01 Understand how you use your vision
Once the frame is selected, we take the measurements needed for the lens design. Where appropriate this can include DNEye® biometric measurements and Rodenstock ImpressionIST® 3D centration measurements of the frame in its wearing position.

02 Measure your eyes and chosen frame
When your glasses are ready, we check the fit, adjust the frame and talk you through the lenses. If something does not feel right once you have worn them in the real world, come back - good dispensing includes the follow-up.
03 Fit, adjust and make sure they work
RODENSTOCK DNEye® Scanner
DNEye® Scanner - measuring more than the prescription
A conventional prescription tells us the focusing power your lenses need. The Rodenstock DNEye® Scanner can capture additional biometric information about the eye, including data that changes with pupil size and lighting conditions.
For suitable Rodenstock lenses, those measurements can be incorporated into the lens calculation rather than relying only on standardised eye models. This allows the lens design to be more closely tailored to the individual eye.

Rodenstock ImpressionIST® 3D video centration system.
Rodenstock ImpressionIST® 3D centration system - measuring the frame on you
The lens also needs to work in the exact position you will wear it. Using Rodenstock digital centration technology, we measure how your chosen frame sits on your face, including the position of your pupils and the relationship between your eyes, frame and lenses.
These measurements are particularly important for highly individualised and progressive lens designs, where small changes in fitting position can influence how the lens performs.
B.I.G. EXACT™ lensesBiometric lenses, made around the individual eye
Rodenstock is our preferred lens partner because its biometric lens technology works naturally with the way we practise: measure carefully first, then use those measurements to individualise the finished lens.
For patients who will benefit from it, Rodenstock B.I.G. EXACT™ lenses can incorporate detailed DNEye® biometric measurements into the lens calculation. This is available across lens designs including single-vision and progressive options.
We are not tied to one solution for every person. We choose the lens design, material and features according to your prescription, frame, visual demands and priorities - and we will recommend a different approach when it is the better fit for you.
Avulux® lenses
Avulux® lenses for migraine-related light sensitivity
For people living with migraine and significant light sensitivity, ordinary sunglasses or generic blue-light filters are not always the right answer. We offer Avulux® precision-tinted lenses, which are designed to selectively filter specific wavelengths of visible light associated with migraine-related light sensitivity while allowing much of the remaining visible spectrum through.
Avulux can be discussed alongside your prescription and other visual needs. It is an adjunct for light sensitivity associated with migraine — not a replacement for medical diagnosis, medication or ongoing migraine care.
We can also discuss other medical or specialised tints where a particular filter has been recommended or may be appropriate.
-
Progressive and single-vision lenses
From straightforward distance or reading prescriptions to highly individualised progressives, we choose the lens design around the distances and tasks that matter to you.
-
Prescription sunglasses
We can make prescription sunglasses for everyday wear, driving and outdoor use, with lens colour and options selected around your prescription and how you use them.
-
New lenses in your own frame
Love the frame you already have? In many cases we can fit a new prescription into an existing frame after checking that it is suitable and in good enough condition for reglazing.
-
Special and medical tints
Tint colour and transmission can be tailored for comfort, visual needs or specific clinical recommendations. We can also discuss specialist filters where appropriate.
-
Sports lenses
Sports eyewear often needs a different approach to lens material, field of view, impact considerations and frame geometry. We can recommend a solution around the activity and prescription.
-
Safety eyewear
For work environments that require protective eyewear, we can arrange prescription safety solutions suited to the task and relevant requirements.
Good to know…
-
Often, yes. We first inspect the frame to make sure it is suitable for reglazing and discuss any risks, particularly with older, delicate or unusual frames. If the frame is suitable, we can fit new prescription lenses without requiring you to buy a new frame.
-
The Rodenstock DNEye® Scanner takes additional biometric measurements of the eye beyond the standard prescription. For compatible Rodenstock lenses, these measurements can be used in the lens calculation to individualise the finished lens more precisely.
-
No. We start by recommending the lens we think best matches your prescription, frame and visual needs, then explain the alternatives and trade-offs. Sometimes a premium individualised lens adds meaningful value; sometimes a simpler lens is entirely appropriate.
-
Yes. We can make prescription sunglasses and discuss tint colour, polarisation and other lens options according to your prescription, frame and how you plan to use them.
-
Yes. We can recommend prescription lens solutions for sport and work, taking into account the activity, frame, prescription and the level of protection required.
-
Yes. We offer Avulux® lenses for people with migraine-related light sensitivity and can also discuss other specialist or medical tints where appropriate. Migraine symptoms should still be assessed and managed with your usual healthcare professional.
-
Yes. If your policy includes optical extras, you may be able to claim towards prescription lenses or glasses. Benefits vary by insurer, policy and remaining limits, so check your cover or bring your membership details with you.
-
That depends on how recent your prescription is, whether your vision has changed and what you need the glasses for. If your prescription is current and your vision is stable, we can advise what is required. If it is time for a review, we will recommend an eye examination first.
