THEALOZ DUO GEL is a fluid gel for use on the surface of the eye during
day time and night time.
You can use THEALOZ DUO GEL when you have moderate to severe
signs and symptoms of dry eye such as discomfort, stinging or irritation of
the eye. These symptoms can be caused by outside factors such as wind,
smoke, pollution, dust, sunny or cold conditions, dry heat, air conditioning,
plane journeys or long hours working in front of a computer screen.
THEALOZ DUO GEL has no preservatives and prevents irritation and
allergic reactions that can occur when eye products containing
preservatives are used. Using preservative-free products is advised when
you have sensitive eyes or are using them for a long time.
THEALOZ DUO GEL is a sterile, preservative-free fluid gel that is
hypotonic and pH neutral, which means it is the same pH as the surface
of the eye and helps hold water on the eye surface.
Its main ingredients are trehalose, a substance present in many plants and
animals, sodium hyaluronate, another substance naturally present in the
eye, and carbomer (Carbopol 974P), that allows THEALOZ DUO GEL to
stay on the eye longer.
Read the instruction manual
Trehalose protects, hydrates and is an antioxidant. For these reasons, it
is essential in the anhydrobiotic process used in certain tiny organism (a
slow metabolism that helps them live in dry conditions).
Trehalose also protects cells by stabilising their membranes.
Sodium hyaluronate is a natural polysaccharide (complex substance)
found in the human eye which holds water to hydrate and lubricate the
surface of the eye. It keeps the solution on the eye surface, giving longlasting relief and cutting down the healing time of the corneal epithelium
(the clear surface on the eye).
Carbomer allows THEALOZ DUO GEL to stay on the eye surface longer,
providing long-lasting relief of dry eye signs and symptoms.
The special combination of trehalose, sodium hyaluronate and carbomer
in THEALOZ DUO GEL hydrates, lubricates but also protects the eye
surface for a long time and with maximum comfort.

The Spectacle Factory is rated 5 out of 5.0 stars based on 20 review(s).


The Spectacle Factory was recommended to me by a friend and my experience from my initial eye test to taking delivery of my new glasses was first class throughout. The attention I received from James during my eye examination was both extremely thorough and professional. He worked patiently and diligently to fine tune my prescription. Robert's involvement in choosing my new frames and lenses was brilliant. At no time did I feel under pressure into making quick decisions regarding the choices made available to me. His expert knowledge and enthusiasm was very reassuring at all times. Having experienced several years of eye discomfort, I am now overjoyed with the difference that the team at The Spectacle Factory have made to my vision. Many Thanks.

I brought my daughters in recently for their first eye tests and I was so impressed with how patient and thorough all the staff were with us. Trying to get a four year old to sit still enough for the scans was very difficult but Ben tried his best and didn’t seem to let it phase him. Claire was wonderful during the eye test itself, employing my 6 year old to be her assistant and making it fun for them both. Not being a glasses wearer myself, I was quite overwhelmed when I was told my 6 year old needed glasses, but Robert helped me to understand what her prescription meant and made sure that her beautiful new glasses fit her just right! Thank you so much to everyone at SF!

Picked my Reykjavik Eyes glasses up Thursday . Robert and his team are outstanding . I am a nervous customer due to bad experiences when I was young . They made the whole experience special and made me at ease throughout both visits . Robert is brilliant regarding frames to suit you no pressure just brilliant support and help . I would wholeheartedly recommend The Spectacle Factory to everyone. Thanks a million everyone.

- Alison Wood


Five stars without any hesitation. I immediately felt at ease and the atmosphere was very welcoming. The service was prompt and efficient. I felt the examination was very thorough and any questions I had were clearly answered. When it came to choosing my frames and what my prescription involved the options available to me were fully outlined. I didn’t feel under any pressure and I felt in charge of the transaction. From entering to leaving it was a lovely experience. I was a little hesitant in the current situation, but my fears were soon allayed as every precaution was taken to minimise the risks. Superior to any high street optician. Excellent all round! EH

Living some 300 miles from The Spectacle Factory visiting was not an option for me, however, after checking all the reviews I decided not only to buy my J.F. Rey frames (seen on an online video by Robert) but also have my Zeiss smart life progressive lenses made by them. I had no worries. After taking advice from Robert the measurements required for the lenses were done locally at a nominal cost. I am now the proud owner of a pair of handmade 'wow' glasses and a very happy new customer. Use them with confidence. The customer service is truely outstanding.

Well they you pay for what you get. It’s definitely true of The Spectacle Factory. There customer service is the best I have experienced anywhere. I was not rushed with any decision and I was made to feel like I was there most important customer. What I paid was an eye watering amount but I got smartlife ziess lenses and frames that are very comfortable. I now also have very clear vision when reading. I thought it was not clear due to lighting in modern offices and homes. Wrong it was bad lenses and persecution not being quite right. Thank you for sorting it all out at the first attempt.

- Heath Christy


ABSOLUTELY BRILLIANT I have been using the Spectacle Factory for a long time, but the latest visit was the best BY FAR..... I desperately needed an eye test, and was fitted in quickly. James, the optician, was excellent , as usual. 4 members of staff were outstanding in the service I received. Robert, Ben and Emma were absolutely perfect.....and Ruth, the manager was excellent, as she always is. The best visit by far...I cannot rate this place higher !!!

- K Rhys


Welcomed by and dealt with Robert during the whole process of choosing through to final fitting. Great service, great range of glasses, really helpful and informative. I would highly recommend

After reading all the positive reviews I decided that a 40 minute drive would be worth it to try and get a new prescription and frames- I wear my glasses all day so need to get this right. I was so impressed with everyone’s desire to be helpful and make sure I was happy at every part of my visit. I wasn’t the quickest at choosing new frames but never felt rushed by Robert. He listened and gave helpful advice as we worked through choosing the frames and lenses I needed. They have a huge range of frames which meant I ended up with a pair I was really happy with. I actually chose a pair of prescription sunglasses as well, which I have been meaning to do for years. I loved the combination of cutting edge technology and personalised service. It’s so nice to see a team that places such a priority on customer satisfaction - they certainly deserve 5 stars.

Fantastic service! I attended the spectacle factory over a year ago for an eye test. They were amazing, and so patient with me! My Polaroid frame broke recently, so in desperate need called the spectacle factory to order a replacement frame. They were so efficient and helpful. Also my frames were covered under warranty and I didn’t have to pay a penny. AMAZING. Couldn’t recommend them anymore!

- Rebecca F


Friendly service, thanks to Robert who took the time and care to ensure that I was happy with my new glasses. I would definitely recommend.

- Paul Wellman


Visited the Spectacle Factory a couple of weeks ago for the first time. James did my eye test and was very thorough and informative. Chose a pair of glasses afterwards with the help of another member of staff. Great customer service. I have always gone to high street opticians before and never sure what glasses suit me. I was allowed to take my time and offered helpful advice. Love my new glasses which I picked up with the week. I will be returning to the Spectacle factory in the future. Far superior in terms of quality and customer service compared to other opticians I have been too.

My wife and I both have great glasses (and sunglasses) from The Spectacle Factory. Right from our very first visit we have been very impressed with the highest level of care and attention to detail, both with eye tests and the choice of lenses and frames. They seem to have a flair for helping you to choose the right glasses. Once your order is ready, nothing is too much trouble to ensure that the fit and the suitability of your glasses is perfect for your needs and that you are completely happy. Their ongoing service is second to none. We can highly recommend The Spectacle Factory..

- Geoff Gosling


Came in today for help with some frames, repaired no questions asked, there and then on the spot Brilliant service

- Alex


All the staff are so helpful and switched on to all your requirements I would recommend them all day what a good experience

- Roy gardiner


The Spectacle Factory offer me the kind of customer service and ability to customise my choice of spectacles that just is simply not available on the High Street. From Initial contact, to delivery of the finished product, you are treated like a loyal friend. Nothing is too much trouble. Unbiased advise, on choosing the correct spectacles for your particular application. A vast range of frames from the very cheapest to the latest designer frames. I choose the Spectacle Factory, because they can provide me with, customised glasses, to align with my particular needs and requirements. Most high street opticians have a 'one size fits all' attitude. The Spectacle Factory does not subscribe to this theory and treats every client as an individual. Their eye sight is very comprehensive and is 50% longer than the industry standard. If you value your eyesight, and want the very best care, this is the place to visit.

- Paul van de Rooy


Rob and the team were excellent help with the professionalism and advise . I will become a faithful member of the spectacle factory!! Thanks again team
