In addition from these benefits, most customers find that the protective Ziena silicone eye cup improves protection from the sun's glare compared to normal wraparound sunglasses, especially if you purchase the optional black eye cup.
When wearing Ziena glasses, your field of peripheral vision is slightly reduced. When trying on the product, ensure that you assess whether it is suitable for your intended use.
We do not recommend wearing them for activities such as cycling or driving, where good peripheral vision is essential.

Optimising the fit of the glasses
Two simple and inexpensive accessories can help you achieve the best seal around your eyes, improving the moisture chamber properties of the glasses and protection from wind, dust, and pollen.
Silicone ear grips @ £2.99 per set
Simply slide the silicone ear grips up the arms of the glasses to rest comfortably and discreetly behind your ears. If the fit of the glasses needs to be tighter, slide them up further to shorten the effective length of the arms.
Toggle adjustable eyewear retainer @ £2.99 per set
An alternative to silicone ear grips that you may prefer if you don't like the sensation of having a hook around the back of your ears.
The eyewear retaining strap attaches to the ends of the ear rests. Loop the retainer around your head and adjust the toggle so that you achieve the optimum fit of the glasses.
You can also wear the strap around your neck to hold your glasses when you are not wearing them.
A safe, comfortable, and soothing therapy for MGD, Blepharitis and Dry Eye that uses gentle heat and moisture to unblock your meibomian glands.
