Below are a few of our frequently asked questions, if you cannot find the answer to your question below please email us at info@ioptix.co.uk and we’ll do our best to answer your question within 24 hours.


Q. What are iridium / lazer / flash lenses?

iOptix: These are all terms given by manufacturers for coloured mirrored coatings on the front of the lenses. The wearer does not see this colour but it does help hide prescription inserts and makes it more difficult for the other people to see your eyes.


Q. Do you ship internationally?

iOptix: YES! In fact many of our orders go overseas, you will be shown the correct shipping charges when you enter your country at checkout.


Q. What is your return policy?

iOptix: If the product is faulty, the product carries a 12 month guarantee. For other returns please see our terms and conditions page: www......


Q. Do you offer combined postage?

iOptix: We offer FREE POSTAGE on all UK orders and set price postage of overseas orders, whether you order 1 item or 5.


Q. What range of prescription will your prescription inserts accept?

iOptix: As a rule we can pretty safely glaze most items upto +/-6.00 outside this we would recommend getting in touch via email or telephone with your prescription and the product you would like so we can advise you best.


Q. Are your products genuine?

iOptix: All of our products are 100% genuine and are supplied to us from the approved distributors and supply channels, so you can ensure all warranties and guarantees will be honoured in the event you should have any problems.


Q. I have snapped one of the arms on my glasses, can i get a new one?

iOptix: Different manufacturers are easier to get spares from than others, 99% of Adidas spares are available within a 4 day window, Rudy within 3 days where in stock. For others please get in touch.


Q. What does insert RX, direct RX and none RX mean?

iOptix: RX is a short hand way of writing prescription. Insert RX means there is a separate frame which clips into the back of the glasses, direct RX means the lenses are glazed directly into the frame so there is one set of lenses and look predominantly like standard glasses and none RX means that the glasses are not suitable for prescription wearers.


Q. The glasses i would like say they are insert RX and direct RX, which is best?

iOptix: This is down to personal preference but to make your decision easier direct RX is often lighter and looks better, the problem is it also often costs more especially if having several sets of lenses. Insert RX is often cheaper and offers more flexibility if you are likely to swap between lenses regularly, it also works out cheaper if your prescription changes.


Q. What are gradient lenses?

iOptix: These are lenses where the base tint of the lens is darker at the top than the bottom.


Q. What are photochromic lenses?

iOptix: Photochromic is the term given to lenses which change colour under U.V. light. iOptix offer various brands of photochromic lenses and these can also have personalised tints applied to them. For further info please contact us.


Q. Can i get vari-focal and bi-focal lenses from you?

Unfortunately we cannot supply varifocal lenses this is because the glasses need to be fitted by a dispensing optician and measured with them on your face which cannot be done online, we also do not recommend them for the majority of sports as they can lead to problems as you are always moving and looking out of different sections of prescription. Bi-focals can be accommodated in certain frames. To be safe let us know your prescription and the frame and we can tell you for definite. There is an additional £30 charge for bi-focals. There are certain frames with bi-focal options added so obviously these are ok.
