History of scuba mask

1. History Of Scuba Mask

2. Human eyes are not able to see underwater, so
diver have to wear a face mask to see
underwater; the reason for this is that the optical
density of water is completely different to air for
which the eye is designed.

3. Origin of scuba mask : 1950
In 1950's face mask was made at home from a
piece of circular glass and bicycle inner tube,but
by the end of the 1950s scuba mask design was
beginning to evolve from this circular design to
an oval, allowing for a wider field of view.

4. 1960
Two panes of glass were added to the sides of
scuba mask. Low-profile masks featured a nose
pocket below the lens that allowed the glass to
be closer to the eyes, reducing the volume of air
contained within the mask.

5. 1980
Silicone has been used. It is more comfortable for
the diver due to its greater flexibility and longer
lasting because it is less susceptible to damage
from sunlight.
