Vision corrector for diving mask

Abstract

The invention discloses a diving mask for vision correction. The diving masks include: frame, a window-capacity home and goggles, in its settings in the inner frame. The vision correction include: connecting component; at least one correction mirror, through its connectivity components described above diving mask installed at the window in front of the mirror. The invention can correct myopia or hyperopia underwater, in particular to help presbyopia in diving at the close observation of things around, such as table read out diving or diving computers, and be able to see around the tiny biological. For young people, this invention can help them watch more clearly underwater biological.

Description

technical field [0001] The invention relates to a vision correction device for a diving mask, in particular to a vision correction device which helps users to correct refractive error during diving and can observe close things more clearly. Background technique [0002] Myopia / hyperopia patients need vision correction in daily life. In general adults, the ability to adjust visual acuity deteriorates with age. People around the age of 40 have difficulty seeing close objects clearly, and this condition worsens with age, commonly known as presbyopia. Patients with presbyopia need to wear a pair of special glasses in daily work and study, such as reading glasses (presbyopic glasses). When diving, patients with refractive errors such as nearsightedness, farsightedness or presbyopia also need vision correction. [0003] The standard diving mask is designed for divers who do not have refractive errors. The windows of the diving mask are usually flat lenses. This lens is made of ...

Problems solved by technology

However, the main problem with the use of such diving masks with bifocal lenses is that the size of the diver's field of view at close range through the corrective lens is small due to the small size of the attached corrective lens and its placement at the bottom of the mask window. and the orientation is limited; divers cannot observe close objects within the scope of the window lens other than the corrective lens suitable for close observation; the position of the field of view suitable for close observation is not conducive to seeing the LCD screen, resulting in water It is difficult or impossible to take pictures down; and when observing the distant landscape, the field of vision is hindered by the small lens suitable for close observation, which is not conducive to vertical diving

This method also has the problem of limited field of view for close observation

Also, modern diving masks often don't have enough room behind the window to accommodate a pair of glasses

[0008] Moreover, there is no diving mask that corrects for astigmatism in the prior art
