- no effect on visual acuity.If the diver uses lenses and wear glasses, then it is better to make a mask with diopters on the order.Otherwise, it may decrease the visual acuity, causing discomfort during use.
- If a small amount of space podmasochnogo has a large viewing angle.When you try on the mask, check whether it is convenient to look around.Generally, the closer to the eye glass mask, the better its visibility.In addition, the glass which is located close, it is easier to clean.

How to reduce the pressure on the eardrums?
