Hi, I’m Sean, and I head up our 5 strong optometric team at DH Thomas. There are a couple of us oldies, myself and Katie Miller (hope that she doesn’t take offence at being called an oldie) and 3 younger optometrists that have joined and strengthened our team over the last few years – Natasha Kumar, Melissa Morris and Nathan Sivajoti. We are here to help you with all your optometric needs in Cambridge and Saffron Walden.

If you have had an eye examination with us recently you will have observed that we have a lot of new equipment;
we have invested heavily in updating and improving what were already well- equipped practices. New OCT scanners (ocular coherence tomography), slit- lamp biomicroscopes in each consulting room, examination chairs and equipment consoles, tonometers (gentler than the previous air-puff type) and most recently an update on our excellent Optos retinal cameras.

It is all very well having this excellent equipment, but we need to understand and interpret the data and information that they reveal. This requires all the professional staff to continue to study and learn, continuing professional development (CPD) is key. Now and again, when time allows, we will put ourselves through the challenge and rigour of higher professional exams. Rest assured that we are not resting on our laurels, and we continue to learn and develop our skills.
In recent years our qualified staff have gained higher qualifications in medical retina, glaucoma, contact lenses and myopia management. Currently various members of the team are studying forIndependent Prescribing and dry eye management. We work closely with our ophthalmology colleagues both in the NHS and for private referrals.

Myopia control is the use of specific treatments to slow the progression of nearsightedness in children. Myopia control measures typically are prescribed by an eye doctor (an optometrist or an ophthalmologist).

Myopia control is important because it may help reduce the risk of vision-threatening complications associated with high myopia later in life — including glaucoma, cataracts, retinal detachment and even blindness.

At DH Thomas we currently offer 3 types of contact lenses specifically for myopia control.

1.Orthokeratology – overnight wear of a cornea re-shaping rigid gas-permeable lens. Suitable for prescriptions up to -5.50 dioptres and modest amounts of astigmatism.

2.MiSight daily disposable contact lenses.

Suitable up to -6.00 dioptres and minimal astigmatism.

3.NaturalVue daily multifocal contact lenses.

Suitable up to -12.25 dioptres and minimal astigmatism.

NB. over-spectacles can be prescribed to use with option 2 and 3 if occasional sharper focus is required and there is residual astigmatism.

Some countries offer low-dose atropine treatment for myopia control, but this is not currently available in the UK.

An innovative spectacle lens design for myopia control, Miyosmart, was made available in the UK, early in 2021. We quickly achieved accreditation to supply this CE marked licensed lens design and have successfully dispensed the lenses to several myopic children. More information can be seen here.


This is a fast developing area of optometry and ophthalmology as myopia affects rapidly increasing numbers of people with estimates that 50% of the world population will be myopic by 2050.

It is great news that some of the restrictions that have been affecting our daily lives are being lifted on 19th July 2021.

At DHThomas, we have strived in making our practices as safe as possible for our clients and our team and will continue to do so going forward.

For this reason, we will continue to operate under the same precautions that we are currently adhering to.

As a reminder, please find below the procedures that will remain when visiting the practice:

  • As we are operating on an appointments only basis, please arrive at the practice 10 minutes before your appointment and no sooner. For patients using our car park in Cambridge, state your name at the gate’s buzzer and when parked wait in your car until a member of our team collects you. For patients arriving through the front of the practice, ring the doorbell and a member of the team will guide you from there.
  • Hand sanitiser is mandatory on arrival and provided around the practice.
  • Wear your own face mask when attending the appointment, however if this is not possible, inform a member of the team on arrival so one can be provided.
  • Gloves are only allowed at the practice if it is for single use only. If you have travelled wearing a pair, these will not be permitted.
  • Our optometrists will be testing eyes with recommended PPE and social distancing will be respected throughout the practice apart from when clinically required.
  • Please attend the appointment alone unless it is essential for someone to accompany you. Children under the age of 16 will still need to be accompanied by one adult.
  • For contact lens wearers, please still wear your contact lenses prior to the appointment. Patients wearing reusable contact lenses will need to bring their own case, whilst daily contact lens wearers will need to bring a spare pair with them.
  • Do not enter the practice if you or any member of your household have any symptoms of Coronavirus being a high temperature, persistent cough and a change in taste or smell.

Due to high demand for our appointments, any cancellations, unattended appointments or rearrangements with less than 48 hours notice, will incur a £30 charge.

If you have any queries regarding this update, please do not hesitate to contact us.

We look forward to seeing you soon.

Kind regards,

Phil and the team at DHThomas.

“Every day I see patients who present with AMD, Cataract, Glaucoma or Flashes & Floaters. These are very commonly occurring conditions. Optometrists are ideally placed to offer routine eye examinations, advice and support to people struggling with their vision. I recommend everyone to have an eye examination at least every two years, and when there are conditions such as AMD and Cataract I often advise people to attend more frequently. It’s really important to come and see us if anything in your vision changes. We’re here to help… don’t wait and risk your sight.”

DH Thomas uses cutting-edge technology for eye care

The world of eye care is constantly evolving and it is vital for opticians to use the latest techniques and technology to provide the best quality of care. At DH Thomas, our mission is to provide this top-quality care, and we have recently invested in three new machines to assist us.

Our new Ocular Coherence Tomography (OCT) machine provides a detailed cross-sectional scan of the macula and optic nerve using infra-red light. So, why is this important in an eye exam? The macula and the optic nerve are crucial for sight. The macula helps translate the light entering your eye into colour, and the optic nerve is responsible for transmitting the information to your brain. But they are both located at the ‘back’ of the eye, which can make it difficult to get good images.

The OCT scans provide our opticians with images that allow them to monitor the macula and the optic nerve and to detect any abnormalities early. Abnormalities in these regions are caused by eye diseases such as age-related macular degeneration and glaucoma. Diagnosing, monitoring and treating (when possible) is critical for the maintenance of healthy vision.

DH Thomas has also recently acquired the latest in Slit Lamp technology. The Slit Lamp is the microscope and light that our opticians use to examine the eye close up. The patient rests their chin on a small support while the optician examines each eye. Using this technology, opticians will be able to assess the sclera, the white part of your eye, the cornea, the pupil, the lens and more. This facilitates the detection of conditions such as cataracts, damage or injury to any part of the eye, or other degeneration. The latest in this technology means that DH Thomas can optimally and efficiently monitor your eyes.

These two new technologies are joined by an additional machine, the Field Analyser. This specialised technology provides an analysis of points in the optic nerve to evaluate glaucoma damage. The accuracy and the speed at which this test works helps in the diagnosis and monitoring of the patient’s glaucoma.

This arsenal of technology allows DH Thomas to provide you with the highest quality eye care to ensure your best vision now and in the future. To book your next appointment with a DH Thomas Optician, contact us here:

DH Thomas are proud to sponsor Jack Stanton-Stock aged 18, who could have a shot at the next Olympic Games.

Jack has been a member of Walden Junior Triathlon since the age of 12 and now he has accepted a place on the Olympic Performance Squad at Loughborough University where he began studying last autumn.

Jack played as many sports as he could while at St Thomas More primary school, and had always been a keen swimmer, first at Saffron Seals and more recently at Dunmow Atlantis Swim Club. At Saffron Walden County High School, he continued to be part of the athletics team as well as rugby and hockey squads but having found triathlon, his love for the multi-discipline sport grew steadily.

In his first year he made it to the national finals. He progressed well and in 2016 came eighth at nationals and in 2017 he came third. Finally in 2018 he reached the top of the podium at national level and became British Champion as well as winning gold at the School Games. He even managed a podium in SuperLeague Jersey in the same month. Jack was recruited onto British Triathlons ENG (England Next Generation Squad) at the end of 2018.

2019 saw him qualify for his first GB kit and start in Kitzbuhel at the European Youth Championships.

Jack has always worn glasses and has known the staff at DH Thomas for a long time, so was delighted when they offered him sponsorship at the end of 2019.

Managing director, Phil Bullen- Brown, said: “All our staff have always been interested to hear about Jack competing and we are very proud be able to offer Jack some sponsorship going forward. We also strive to offer him and all of our customers, the best possible eye care.”

Although 2020 should have been a great year for Jack to do some more racing in Europe but it was not to be as no racing took place.

Jack did however celebrate his 18th birthday in the first national lockdown. He celebrated by spending 18 hours on his bike to raise money for the NHS and covered more than 500km and raised more than £5000.

He was of course, proud to wear his DH Thomas cap for the entirety of the event and Phil popped by outside to support and even joined Jack virtually for a while on the bike.

Jack has since been training hard and hopes to have a successful 2021 with a qualifier for the European Championships in May and then World Championship qualifiers in August.

Phil added: “We have big hopes for Jack’s future and hope to see him at the commonwealth games, the World Triathlon Series, and of course just maybe Paris 2024!”
