Our Testing Procedure

Our Testing Procedure

One of the things that sets us apart from our competitors is our thorough testing. Not only do we test our sunglasses to all international sunglasses standards, we make sure they exceed all the standards. This is so we can provide features that we believe are extremely important for children’s sunglasses like full 100% UV protection – because children’s eyes don’t filter UV rays like adult’s eyes, true G-15 lens colour – because this is the only colour lens that has no loss in clarity and no colour distortion even for colour blind kids, and impact resistant A-grade polycarbonate lenses. The following video shows just how impact resistant our lenses are with this drop ball test. Blink and you’ll miss the steel ball being shot into the lens. To pass this test the lens can not crack or break and the lens must remain fixed in the frame.

We then go that extra step to make sure our sunglasses will give you value for money using materials that will take all the punishment kids will hand out. In addition, we make sure that all the materials used in making our sunglasses are non toxic because we know babies will always start chewing on them. There is no sacrifice in style either, for example we make some really pretty models that are printed with roses and other flower designs that are heat transferred on to the frames. We know the frames and the dyes used in the printing are all non-toxic but we don’t think its good for babies to eat this printed material in case it peels off. So we subject these sunglasses to a cross cut test so we can be confident it will not peel. The following video shows the cross cut test being performed.

This following impact test is not an international standard sunglasses test but we don’t want our sunglasses frames to break or the lenses to pop out easily so we perform this impact test by dropping a one kilogram steel block – 100mm onto the frame.

We also carry out a torque test, where the temples are rotated 90 degrees to each other, both clockwise and anti-clockwise, performing 100 cycles. The following pictures show how this test is done. To pass this test the frame can not break or the lenses can not pop out.

This following oven ageing test is also not a part of any international sunglasses standard but in the real world sunglasses might be left on the dashboard of a car in the midday summer sun so we carry out this test over 7 days in an oven set at 70 degrees. We then inspect the sunglasses for blemishes and flaws and subjected them to a number of further tests.

There are many more test that we apply to our sunglasses but we don’t want our competitors to know all our secrets of how we remain the world’s best baby and kids sunglasses manufacturer.

As you can see from some of our testing procedures we really put our sunglasses under a lot of different conditions because we know some kids will put them under similar stress.

When we test other brands and non-branded sunglasses we still see many that don’t even pass the compulsory international sunglasses standards. And when testing to our standard the majority fail all or most tests with only a very small number of brands that come close.

It’s this extra attention to detail that makes us the leading supplier of high quality baby and kids sunglasses in more than 65 countries. Don’t your kids deserve the best?
