heart2 City Eyes Opticians

Charles was the most professional ophthalmologist I have ever met, his service was clearly above and beyond what I was used to with other specialists I had met in the past.

I have been introduced to Ortho K six years ago and have never looked back. Having an active lifestyle, as well as a job that required a lot of computer work, soft lenses only worked as a solution for a short while, resulting in my eyes being very dry and uncomfortable. Having tried Ortho K has changed my life – not only it is an amazing feeling to be free of glasses or lenses throughout the day, but my eyesight has also stabilised.

Dealing with Charles and the girls working for City Eye Opticians is always a pleasure and their attitude is very personal, in fact every time I come back now for my regular check ups I feel like I’m coming to visit family! Ortho K and City Eye Opticians is a real find! I highly recommend to anyone who wants to find freedom in their daily activities and feel free from discomfort of glasses or lenses – once you try Ortho K you will never look back!


Charles is an excellent optician, providing a personalised, efficient and expert service.

Charles has looked after my eyes for several years. He combines current expertise with a delightful clinical manner. I trust him implicitly. The service is always on time. His staff are equally delightful.

I am very pleased, 6 months on from taking up Ortho K overnight eye correction lens. 5 years ago I discovered that I had become short-sighted, since that time I have struggled with glasses – hate them; soft contact lens – OK but really dried up my eyes and was really thinking that the only option was surgery, which I was concerned over since I felt I would need correction again as I get older.

Ortho K has just taken away all these issues and since I don’t even have to wear them every night, the whole arrangement for me is perfect.

I’ve worn glasses every day since the age of 11, a total of 27 years. My prescription is -2.75, which means that I’m a perfect candidate for Ortho K. I had an initial, very thorough eye examination with Charles Babumba, which took just over an hour and included the regular sight and glaucoma tests. Charles then performed a series of further tests to measure the shape of my eye (this determines the extent of my short-sightedness). This contour map was then used to make my individual contact lenses; he also checked under my eyelids and after checking inside my eyes, took a Polaroid picture of each eyeball to check the health of my eye. I really felt that no stone was left unturned and had complete faith that the procedure was right for me.

About a week later, I returned to Charles’ office and tried on my new lenses. Unfortunately one of the lenses wasn’t strong enough for me, but in a couple of days I received a replacement one. You have to have the lenses on every night. From the beginning, I found them really easy to wear and fell asleep almost immediately. I had no trouble inserting them, but needed a bit of practice in taking them out – after the first night I had to travel to Charles’ clinic so he could take them out for me! When he took them out, the result was amazing – I could see immediately! It was a very odd sensation to be able to see properly without wearing glasses – I had to keep touching my face to check whether I was wearing them or not. It’s now been seven weeks since my first appointment and my vision’s still good. I’m experiencing a bit of glare at the moment, but this gets less and less each day. The effect of the lenses is amazing and to be able to see without any glasses is a miracle. The treatment took a few weeks to work on me, but some people take less time. My advice is to be patient and stick with it – the benefits far outweigh the settling in period. I’m a convert!

Having worn only glasses for over 20 years, I was reluctant to try vision-correction lenses. However, in the first week of use I was pleasantly surprised by the quick improvement in my sight.

After 6 months, I find that I can enjoy 2 to 3 days of good vision from using the Ortho K lenses, so I don’t even have to wear them daily. They are comfortable and convenient, and fit in well with my busy daily routine. I would highly recommend them to anyone considering such a move.

If you are a short-sighted sportsman or woman, work in a dusty workplace or suffer from dry eyes, wearing glasses or contact lenses during the day may not be an option. The Ortho K system – contact lenses that correct short-sightedness while you sleep – could offer a solution. Wearing the tailor-made gas-permeable lenses overnight reshapes the cornea (the dome shaped window covering the front of the eye) to its correct position, giving the wearer 20/20 vision upon waking. The sight correction generally lasts for the entire day, and sometimes longer: some wearers find they may only need to wear the lenses every other night. Swimmers, rejoice: you can wear them in the pool, too. Although the lenses don’t cure short sight, some studies have indicated that using them may slow down the progression of myopia. The technology has been around since the 1960s, but has only recently become affordable.

Optometrist Charles Babumba, of City Eyes in the City of London, is prescribing Ortho K lenses to many of his patients, including his 13-year-old daughter, and monitoring the results. ‘The lenses are not appropriate for everybody,’ he says. ‘They are not suitable for people with diabetes, high blood pressure or very high prescriptions (over -6), or astigmatism. They only work when the wearer is asleep and must be worn for at least six hours, so some people’s lifestyles might rule them out.’

Marvellous exam from consummate gentleman.

Mary K.

Thank you very much for the thorough check up and consultation. As I’ve neglected checking my eyes for many years or changing my glasses, it’s a great relief to know my eyes are in fairly good shape. Many thanks again and best regards.


I originally contacted Charles Babumba after seeing him talk about Ortho K on ‘This Morning’. I had a -2.5/-2.0 prescription (with slight astigmatism) which meant I had had to wear either glasses or contacts lenses since the age of 23. I have always been very ‘sporty’ and both glasses and contacts were a source of annoyance within everyday life – especially when swimming. I also ride a motorcycle and again glasses we’re obstructive, and contacts used to irritate after long term wear. Ortho K seemed to be an ideal solution. It would mean I would be correction free during the day, my eyes would get oxygen to them, it was reversible, affordable and seemed relatively risk free (especially when compared to Laser surgery which would permanently compromise the integrity of the eye). After an initial consultation (involving a thorough examination to ascertain suitability) I was fitted with my new lenses, and instructed how to insert them & the necessary aftercare. Hard lenses we’re a little bit uncomfortable to start with, but like anything new my eyes soon adapted.

The immediate results we’re amazing, and for the first time in years I could see clearly without correction. Over the following months my eyes improved further and my Ortho K lenses just became part of my regular routine – a bit like brushing your teeth! Now, after nearly three years under Charles’ care I have had no problems whatsoever – no soreness, infections etc. I observe a meticulous hygiene regime which I think really helps, and cannot now imagine being dependant on glasses or daytime lenses. I am able to play all kinds of sports, ride my bike and wear my sunglasses unhindered. Charles is particularly passionate about eye care, and as a customer this gives a real sense of being in the hands of an expert. He takes the time to explain what and why he is doing things and his overall approach is not just about correcting my prescription but also keeping close tabs on ongoing visual & overall health. Much of which I understand can be prevented if identified early enough. I guess the ultimate endorsement is the fact that whenever I meet someone who still wears glasses or contacts I cannot help myself but to make them aware of Ortho K, Charles and City Eyes. Meeting Charles and using Ortho K really has been life changing and I hope to be under his care for many years to come.

Charles demonstrates an impressive depth of knowledge and experience in the area of eye care and health. Certainly, this was the most comprehensive and thorough eye examination that I have ever had. The level of service is superb, and the willingness to accommodate a busy schedule all combine to make it worth the trip to London for an appointment. I highly recommend Charles and his team.


I have been using Ortho K overnight vision correction lenses for over three years and am delighted with the results. Before hearing about the procedure I had been considering laser surgery but was concerned about potential side effects so I was pleased to find something non-invasive and completely reversible. As a keen sailor I was also looking for a better solution than my existing glasses which were prone to condensation and smudging from rain or spray in rough weather making them far from ideal.

Since using the Ortho K lenses I have been very impressed with the dramatic improvement to my vision, so much so that I do not need to wear them every night. I can now see distant objects more clearly than ever before which is particularly useful when trying to identify navigation lights at sea in the dark, something I used to find difficult in the past even with my glasses. Driving is also much easier, particularly at night. Never having worn any kind of contact lenses before I was initially a little concerned about whether they might cause any discomfort at night but this has proved not to be the case and they have never disturbed my sleep. Overall I am very pleased indeed with the lenses and would recommend them to anyone interested in trying the procedure. I would also highly recommend the excellent service I have received from Charles Babumba at City Eyes Ophthalmic Opticians whose in-depth knowledge and professionalism have impressed me from the initial consultation right through to the continuing aftercare.


Thank you for the very thorough eye test, indeed the most thorough I have ever had. I am very pleased with the excellent service I have received from you and will be certainly using you again in the future.


I was very impressed with the service offered by yourselves and Tom Davies. I can honestly say that they are the best fitting spectacles I have ever had, and I have been wearing glasses now for well over 20 years. The first thing that impressed me about them was their combination of simplicity and strength and style in the design, and the quality of the materials used in the construction. The best compliment I can pay them is that I sometimes forget I am wearing them at all! And it was very good of Tom to actually offer to fit them himself at his studio, a level of service never before experienced. I would certainly recommend them to anyone who wants to purchase a stylish, comfortable and well made pair of spectacles. I will definitely buy another pair.

In the two and a half years since our fifteen year old son has been using Ortho-K lenses, his mild myopia has been stable and his prescription has remained unchanged. Also, he has found that wearing his lenses just once every five nights or so is sufficient to maintain his vision, which is very convenient compared with glasses or ordinary contact lenses. We feel that he is receiving the best possible treatment at City Eyes, and that his myopia would have continued to worsen if he had stayed with his traditional ophthalmologist.

Clive and Sarah

I have been seeing Charles for my eyes for over a decade now. Although I no longer live in the UK, I still see him once or twice a year when I am in London. Ortho-K in particular has benefitted me greatly.

Raj Jit

Hi Jenna, many thanks indeed for your help. I cannot tell you how I appreciate it, you really got me out of a fix!


Thanks so much for your great care as always.


Thanks, Charles. You are definitely the best optician I’ve ever had.

Steve D

Charles provides excellent care and expert advice, always using the latest technology to ensure best practice. His staff are always pleasant and helpful.

Freddie M

I have always longed for freedom from my glasses equally from a social, lifestyle and working point of view. Ortho K lenses have by far exceeded the performance of any other regular contact lens, gas permeable and soft lenses alike.

Mr N. Taylor

Charles has been my optician for many years. I am very pleased with his detailed check-ups, his professional and personal approach. He follows latest technology and information in his area. His eye control equipment is always latest technology. I trust his knowledge. I can strongly recommend his eye checkups.

Zeynep E.

Charles is an excellent optometrist, having a wide knowledge of the area, keeping abreast of current developments and using excellent equipment. His sourcing of products is wide-ranging, with items such as drops and contact lenses that may well not be offered by his peers. Follow-up and service are also strong, and I have referred friends and family to him.

Charles Weston

It was a pleasure to meet you and I am very happy with the lenses you provided me. I will get back to you when I need new ones.

Project Assistant, Museum of London

I have been seeing Charles Babumba for quite some time now – ten years or so and he has always been extremely professional and conscientious as well as being a thoroughly nice guy. He makes the whole experience friendly and easy. I first heard about Ortho K from a newspaper article and it sounded exactly what needed and when I found out that Charles is one of the leading exponents I was delighted.

I am short-sighted (-1.5 in both eyes) and so need to wear contacts or glasses in order to enjoy decent vision. Glasses were not always convenient and lenses, even soft dailies, became uncomfortable especially in the evenings as I have extremely dry eyes as a result of rheumatoid arthritis. It got to the stage where I would rather not use anything – except for driving etc – but did mean I was squinting a lot.

I did look into laser surgery but didn’t really like the idea of the procedure and because of my arthritis was turned down by various providers. Ortho K was my saving grace. I won’t go into the details as you can have it explained in more detail on Charles Website but I will say it is brilliant. Right from day one the effect was dramatic as soon as I took the lenses out I was able to enjoy clear focused vision which lasted all through the day. I have been using them now for about two months and have now progressed to the stage where I wear the lenses for one night and the effect lasts for three full days before I need to put them in again. How cool is that. It is such a simple process and this was made particularly clear on my recent holiday as I was able to sunbathe and swim and snorkel and see without having to put lenses in and take the out as I used to.

Charles was excellent, explaining it all to me and the whole process took about half an hour to map my eyes and gather the information to allow him to make the lenses which I picked up a week later. It really is that simple and I cannot recommend both the procedure and Charles himself highly enough. If you are thinking of an alternative to glasses or lenses you have to call him.

Duncan Perry, a 33-year old sales manager from Fulham, west London, has been an Ortho K guinea pig for four months. Though only minimally short-sighted, without correction he squints and is very tired by the end of the day. ‘I’d rather not wear anything, but I didn’t fancy laser surgery,’ he says. ‘My optometrist recommended I try Ortho K, which cost about the same as my ordinary lenses. They are harder than normal lenses and at first were more uncomfortable to put in and take out. You have to use eye drops to lubricate your eyes. But I’ve got used to it and, of course you’re asleep while they’re in, so there’s no prolonged discomfort.’

I have been raving about you and Ortho K to my Deputy Editor, she can’t believe it!


These lenses have transformed my life. I no longer have to worry about dry eyes which I always experienced with normal contact lenses – even those designed for dry eyes! I am rid of glasses and my eyes feel much healthier than ever before. The freedom the lenses have given me and the professional and attentive care Dr Charles has given me, makes me one very, very happy customer. I would thoroughly recommend giving it a go.


Just wanted to say that I love my Maui sunglasses. They are incredibly effective and comfortable! Thank you for the introduction!

I wore semi-permeable contact lenses for about 30 years and thought my eyes would be too old to do anything else with. I had considered laser treatment but was worried about something going irreparably wrong. Having worn Ortho K lenses for just over a year now, I would not be without them and would hate to return to lenses. I really like the simplicity and practicality of wearing lenses at night so that you can see during the day. It’s great to be able to see clearly as soon as you wake up and it’s marvellous not to have to deal with fibres and dust getting into your eyes with lenses. Now I can put make-up on my eyes and not spoil it by putting lenses in and making my eyes water for one reason or another. I can wear eye area moisturiser without the oil seeping into my lenses. My eyes are in better health; less dry and tired looking and this has impacted on the overall look of my face since I don’t wrinkle my eyes up as I used to, especially by the end of the day when my eyes were tired and the lenses drying them out. I’ve been swimming and snorkelling this summer and could see perfectly for the first time. I didn’t have to keep my head out of the water for fear of getting my lenses wet. I could dive as much and as spontaneously as I wanted and I can now take a shower without the palaver of removing and washing lenses beforehand and then replacing them afterwards. I don’t need to wear glasses at any time any more, I can just – see!

What’s great is that Mr. Babumba gave me a really thorough eye check -up, picking up on straight-forward eye health issues that had not been noticed before and which were sorted out promptly.

What’s wonderful is that the Ortho K lenses start to be noticeably effective from day one and it’s not long before the ‘miracle’ of near perfect vision occurs. I still find it amazing. The lenses are not entirely perfect sometimes, especially in half-light or if you sleep with your head at the wrong angle, preventing the lens from doing its job fully in the night. Night time driving can be tricky as headlight glare gets refracted oddly at times but this does improve over time. It’s useful to always have some low-strength soft lenses for the odd occasion. Apart from that, I love my Ortho K and wish I’d tried them years ago. Thank you Ortho K Team!

J. H.

Thank you for the speed and efficiency with the treatment and spectacles.

Richard K.

I was fed up with glasses, couldn’t stand the constant dry eyes contact lenses gave me and wasn’t brave enough to go down the laser surgery route. I really didn’t think I had many options left but then Charles, my optician, introduced me to Ortho K lenses and I haven’t looked back. They truly are amazing. I pop them in at bedtime and take them out in the morning and my vision is excellent all day. It really is that simple. Most people are quite incredulous when I tell them about Ortho K lenses and how they work, and I can’t believe that more people don’t know about them. I certainly couldn’t be without them now. Go on, give them a try, I guarantee you won’t regret it!

Jenny C.

My friend has been raving about her examination. I was delighted to recommend her to you.


My experience at City Eyes has always been excellent. Charles and Jenna are professional, courteous and very knowledgeable and I know I am getting excellent value for money. The eye tests are very thorough and Charles always takes his time to explain fully each aspect of the examination. I have recently purchased a pair of glasses and Jenna was most helpful in assisting me with my selection and the final fitting. Ordering lenses and booking appointments couldn’t be easier. The level of service is very high and I am happy to be a patient at City Eyes.

Sara Jerome

Ortho-K has been great for me. For a fact I know that my eyesight has not deteriorated in the last two and a half years. This would not be the case if I was wearing glasses.

Joseph (15 yrs)

Hi Charles, I just wanted to say that Jenna has been superbly helpful and I am on my way to NY with my lenses. Excellent client care from City Eyes as always. Grateful thanks.


Thank you so much for your kind understanding and patience over the past years – your kindness and great service will be remembered always.


It was nice to meet you last week and thanks for your advice.
