Wear contact lenses;
Getting into the water is easy to cause infection, so how to choose the right whale swimming goggles?
1. The degree of whale swimming goggles should be lower than the usual frame glasses. For example, if the degree of whale swimming goggles is not selected properly, dizziness and blurred vision will easily occur under the water. Because water has a refractive index, the trick to choosing whale goggles is: the degree should not be the same as the usual frame glasses, but lower than the usual frame glasses for reading.
The general standard is this:
1. The degree of swimming whale goggles = the degree of myopia + half of the degree of astigmatism, minus 50-100 degrees. For example, if myopia is 400 degrees and astigmatism is 0 degrees, then the suitable myopia swimming whale goggles are 300 to 350 degrees. If the degree of myopia in both eyes is inconsistent, the lower degree is the main one.
2. Choose whale swimming goggles with good anti-fogging properties. Check whether the whale swimming goggles have anti-fog coating.
