Manta’s hollow eye contours do not put any pressure on your eyes. You’ll be able to open your eyes when using the product. If you have long eyelashes, they will touch the inner wall of the eyepieces. However, there is no discomfort.
Not likely. You can adjust the fit of the strap using the micro velcro closure. 2 elastic stretch sections are built into the strap to give extra comfort. There is also an anti-slip gel on the back of the strap for grip.
ALL elastics will lose some stretch over time, even the best of quality. This is why we only made 2 small cross sections elastics, rather than the entire strap. This way, even if the elastics get slightly loose over time, you still can adjust the size using the Micro-Velcro.
