Whale goggles are used by children with myopia

November 26, 2021

The swimming goggles factory specializes in the development of swimming goggles for myopic children. The glasses usually worn are lower. If the power of the swimming goggles is not selected, the symptoms of dizziness and blurred vision are more likely to occur underwater, which is worse than not wearing them.

Because water has a refractive index, the trick to choosing swimming goggles here is: Do not use the same degree as the frame glasses you usually wear, but lower than the frame glasses you usually wear.

The general selection criteria are as follows:

The degree of swimming goggles is equal to the degree of myopia plus half of the degree of astigmatism, minus 50 degrees to 100 degrees.

For example, if you have a nearsightedness of 400 degrees and an astigmatism of 0 degrees, then the myopic swimming goggles for you are 300 degrees to 350 degrees. In addition, if the degree of myopia in the two eyes is inconsistent, the eye with the lower degree will prevail.

Choose swimming goggles with good anti-fog performance

Check whether the swimming goggles have an anti-fog coating. The anti-fog coating contains hydrophilic chemical components, which can absorb more water vapor, and the anti-fog coating of good swimming goggles is not easy to fall off.

Try on swimming goggles to eliminate health risks

Before buying swimming goggles, try them on first, and gently press either side of the swimming goggles toward the eye socket. If you feel a certain amount of suction and do not feel that the suction is too large, then the size of the goggles is relatively appropriate.

Then try on the strap to judge whether the tightness of the strap is comfortable, and whether the softness of the gasket at the eye socket is just right. If it is too hard, it will cause eye bone pain over time. If it is too soft, it may be possible. There is a risk of increased intraocular pressure

There is a little trick when trying on. You don’t need a mirror strap and stick the goggles on your face. If you feel a slight absorption, it means that the goggles and the face fit well. The key point is to judge whether the frame, eye mask, and eye socket are good. Perfect fit, is the length of the nose bridge just right? Whale goggles custom manufacturer.
