The effectiveness of our protective glasses and sunglasses depends on how well they fit you.
How should the eye cup fit?
If the eye cup creates a good seal all the way around your eye sockets, the glasses will provide an effective barrier against wind, dust, and pollen.
A good fitting eye cup stops eyes watering outdoors in cold winds, and will create the "moisture chamber" effect that is necessary to give you relief for dry eye symptoms.
The eye cup is not intended to fit tightly like a swimming goggle. It should be resting comfortably on your face, in contact with your front temples, along your eyebrow line and against your cheekbones.
The ideal fit for effective dry eye relief or wind protection is when the glasses are occasionally starting to mist up slightly in the corners of the lenses.
Helping you make an informed choice of which product to buy
We aim to give you as much help as you need when choosing which glasses to try. This includes our Buyers' Guide and also the option to call or email John to discuss your requirements.
We recommend buying two or three pairs of our glasses so that you maximise the chance of finding the ideal fit. You can use our free returns offer if you buy more than one frame, keep one and return the others.
We will refund you promptly the cost of any returned products, provided that they are in good, saleable condition.
You've just received your order, now how do you tell if it fits properly?
So you've just received your glasses and you want to try them on to see if they work for you. Here are the questions to ask yourself that determine whether they are the right choice for you.
Put the glasses on
- Do they feel comfortable to wear?
- If so, they are probably a good fit
- Does the eye cup pinch anywhere?
- If so, the glasses are too close fitting. See if you can adjust them to ease the fit or request an exchange to a wider product
- Are there gaps where the eye cup does not touch your skin, for example at the sides, or along the eyebrow line?
- If so, you need a smaller, more close fitting model
- Does the frame feel big on you?
- If so, you need a smaller, more close fitting model
- Do the glasses tend to slide down your nose?
- If so, you need a smaller, more close fitting model
- Do the lenses mist up excessively when you are wearing the glasses?
- If so, they may be too small for you and fit you too tightly. Please click this link for advice on reducing lens misting
Go outdoors with the glasses on
- Do your eyes and eye sockets feel insulated?
- If you stand out in the wind, does the eye cup provide an effective barrier?
- If yes, they are probably a good fit
- If no, they are not a good fit for you and you should consider exchanging them for a different model
- Do the lenses mist up too readily?
- If so, the glasses are too close fitting. See if you can adjust them to ease the fit
- If that doesn't solve the problem, please click this link for advice on reducing lens misting
Go for a walk or a bike ride
- Do the glasses protect you from headwinds and side winds?
- Do your eyes stop watering?
- Do your eyes feel more comfortable and less raw after a period outdoors?
Test the glasses indoors
If you bought the glasses for indoor use, try wearing them for a couple of hours in the situation in which you need relief, for example in the office in front of your computer.
- Do your eyes feel more comfortable, less dry and sore after you have been wearing the glasses for a while?
- If yes, then the glasses are a good fit.
- If no, you are welcome to contact us to arrange an exchange with a different sized product.
You're welcome to exchange the glasses if they don't fit properly
We are confident that there is a frame in our range of dry eye glasses that will fit you and provide the protection and relief that you need.
Most of the time you will get it right first time, but if not, if you find the glasses don't fit well enough to be effective, you are welcome to exchange them.
