hi all. i'm going to try attach photos of my goggles. they work well, i can read my watch clearly and see people 50m away underwater(in a pool). the main problem is that i see double as the lenses are not alligned properly with each other. this could proberbly be fixed by filing down the plastic lense holders in a way that changes the angle of the lenses. or i might just use a lense over one eye and close the other. Although i'm pretty happy with them i'm still prefering to use a sphera with noseclip.(i can take it to 30m before i have to touch my nose to remove the noseclip to equilise the mask)
the plastic pipe the lense clips into is taken from a garden hose fitting. it has a 1 or 2mm narrowing/bottle-kneck which the lense butts up gainst. one of them. i used was the perfect diameter and the lense cliped in securely without the need for glue. the other one (of another brand i think) was a hairs-with to wide and so i used a bit of superglue to anchor it. i used a bit of superglue on the rim of the pipe to attach it to the inside of the goggles lense. i did a bit of experimenting to get the lenth of the pipe right, taking it out a few times to file it down. its about 9mm now, making the flat surface of the lense about 7mm of the goggle lense and just beyond the reach of my eye-lashes. bringing the lense closer to the eye seems to offer better near-field vision at the expense of the far-off(or is it the other way arround?). experiment to find the best compromise.
conveniently, the pipe comes with 3 holes down its side which allows water to enter.
and incase you cant make out from the photo i have put the lense with flat side closest to eye, convex side facing out.
dont know if this is the best method but i think it might be easier than the method using two half-pipes with notches cut into them. cheers
