The same product as Thealoz Duo in a bottle but in convenient vials. Ideal for single use and perfect for travelling.

The drops can be applied as often as necessary throughout the day.

My option recommended this for my dry eyes and it is helping me to be able to wear my contact lens
This does definitely help to relive the symptoms of dry eyes but the tubes are single use and cannot be resealed. Half of each tube therefore has to be discarded - making them poor value
Our ResponseProduct :Glad you find that Thealoz Duo helps and for regualr use try the bottle version which is still preservative free and so much more cost effective.

efficient response to order
Great for flights
Excellent drops for dry eyes.
To be honest i bought these by mistake on the Website mistaking them for the Thealoz Duo Gel Unidose - I use the Gel Unidose at night before going to bed for night long relief - I have though found the Thealoz Duo Unidose eye drops useful for taking out and about for times that my eyes need a bit extra support - so i will be buying these again in future.
great for flights
My eyes seem to be much more comfortable using this product.
Have used other eye drops before and my eyes still used to be dry.
I have only used these a few times but so far, they are good.
Very prompt and efficient service
Great for dry eye and convenient to keep in your bag
Good eye drops can take them when you travel as they are unidose.
I haven't used these yet as I wanted them for my forthcoming holiday and thought they would be more convenient but I am sure they will be just as good as the Thealoz Duo.
Often I have wished that I had some eye drops with me only to find the bottle is at home. Now I can keep some in my handbag.
I am a regular customer and Your products, postage, proce and service is very good.

I would have made it excellent but some of your sales are misleading. I was very disappointed with your but 2 get one free Thea duo individual with no clarification that it was for one box only. You need to be clearer on that. I would have purchased seperately in that case.
Happy with product
My rating is not for the drops them selves but for the packaging. Unlike other unidose drops that I have used, the top will not go back on which means that they have to be discarded straight away and can't even be used for a few hours which is what I do with other makes. Secondly, when the top is taken off it leaves a small sharp bit behind which can scratch the eye when the drop is administered. I've not had this problem with other makes. For both these reasons I wouldn't buy this again.
Our ResponseSorry for the issue with the expiry date and glad we were able to resolve quickly for you. With regard to the vials I will be in-touch directly as the manufacturers take such report seriously to try and improve their products.

These eye drops are excellent, have the best of Hyabak and Thealoz, they keep eyes very lubricated, the best I have found for going through the night.
Best yet
These eye drops work well for me at night time, keep eyes well lubricated
