Different set of lenses to correct sight problems

Different set of lenses to correct sight problems

What is the focal length or strength of the lenses you supply with the Dive?

I have a bad sight and shifting lenses closer to the screen (to correct my bad vision) has several negative effects:
- reduces the immersive effect: only a small round circle is visible (like looking into a submarine window)
- blows up the central pixels to much (central pixels are very big, pixels on the edge are significantly smaller)
- most importantly reduces the visible area of the screen - only approx. 1 quarter of the screen part dedicated to single eye is visible

Don't take me wrong - I'm happy with the Dive hardware, I understand it just can not fit everybody. My plan is to buy a different set of lens (less strong) that would correct my eye issue. Knowing the current focal length would help me to choose the right parameters of the new set.
Thanks for the answer.

Ok, I got the answer and a new pair of lenses :-)
If anybody is interested the focal length of the default lenses is about 50mm (about 20 dioptres), diameter 25 mm. I normally wear -6 dioptres (myopia) that means my new Dive lenses should be about 14 dioptres that is focal length aprox 70mm. I bought the new lenses on ebay - Plano convex lens, mine were marked as PVL-70-25 (which is 70 mm focal length, 25 mm diameter). I can confirm all the issues I descibed earlier are gone, hoewer the imersivenes is still not ideal as now I can see the edges of the phone screen (just slightly on the left an right side, but I guess that' how everybody else sees it). Anyway, it's definitely an improvement for me. Hope it helps.
