Glasses with diopters are quite an important thing when it comes to swimming.
Goggles are divided into four groups: the first group is for children, the second group is for amateurs, the third group is the starting glasses, and the fourth group is goggles. Those for lovers, in turn, are also divided into groups, into three groups. The first is women's glasses, the second is men's glasses, and the third is unisex.
We are interested in a group with glasses that have diopters. These glasses will be indispensable for those people who in everyday life wear any means for correcting vision, for example, glasses or lenses.
Dioptric swimming goggles are designed not only to protect the eyes from water, but also for good vision under water.
In fact, diopters in them are sometimes needed not only for those who have vision problems. The fact is that under water everything is seen differently than in the air. Even with good vision, opening your eyes while under water, you will see everything blurred and fuzzy. Our eyes are not meant for water.
Its refraction and the refraction of air are different among themselves, hence the difference in vision. Light is refracted through water, and therefore a clear image cannot focus on the retina.
Some people believe that you can safely swim with a mask, wearing contact lenses for vision. In fact, there is a big risk that water gets under the mask, which simply rinses off the lenses, and you can lose them, because they are practically invisible in water.
An interesting point - glasses for swimming with diopters are assembled independently. It is a matter of the fact that these glasses are sold in parts, and at home everyone must assemble them independently. The fact is that everyone has different units of vision, so a particular eye requires individual adjustment. It turns out that you need to separately buy the right eye, left eye, as well as a special kit, which contains nose bridge, elastic and carabiners for attaching lenses to the elastic.
How are diopter glasses designed for swimming? Ordinary goggles are taken, but instead of ordinary lenses, diopter lenses are inserted. If the eyes are different in quality of vision, then the lenses for each eye can be made different.
Variants are also possible when diopter lenses are inserted into the glasses by the manufacturer. It is such a design (solid) that completely protects against the flow of water. Another point that you should pay attention to is that this option is suitable only for those who have the same lens power.
It is important to note that the power of the lenses does not work for a specific amount in air, but only in water, that is, in air you will not see so well in them as in water.
