RHO lens for headplay HD install tips


Hello there!
Im brand new to fpv and my headplay HD came 2 days ago.
My RHO lens came a day later.
I enjoy the RHO lens much better then the headplay lens.
mine came in a timely manner and are constructed beautifully...

The instructions are not as clear as i would have prefered.
I was not sure if i was to screw the halves together after removing the stock lens or not.
I was also unsure of how far or near the lens should be.
The halves hold them in place, yet how and where??

I first unscrewed and removed the stock lens with gloves on.
then screwed it back together only to find the RHO lens
would not go in properly.
I found that keeping the front screws loose and the rear screws removed was the easiest.

(Screwing in an antena and turning on the headset is great to do at this point.
Put it on hdmi and let the blue screen shine light so you can see top the strap loop on the inside.)


I figured this method of instal after a lot of trial and error.
I did this write up to save you some time and perhaps damage.

The head plays should be upside down on a table with the opening facing away from you. Do not attempt to fit the lens with the head plays in your lap facing down. You could drop the lens on the screen... (don't ask how i know, yes my screen is ok.)

To prepare the shell for the lens install press both halves together with the rear (open side) screws removed and the front (flat side) screws loose.
Grab the lens with thumb in the nose bridge on one side and index on the top corner.
Insert the top of the lens first while using your pinkys outside to pry the headplay case apart ever so slightly.
Then slide in the bottom part of the lens.
The point here is to just give your self enough movement room to slide the lens around yet not let it fall.


Use the strap to center the lens in the opening. Put the lens in front of the strap as close to it as possible yet still allowing clearance.

Next view the bottom of the lens and try to make it parallel with the screen.
(thats rite, i used both foams.
i like it plush.)

Adjust the lens accordingly and then use a bit of pressure to push the case halves back to tight when you are satisfied with the placement.
retighten the front screws and install and tighten the rear screws.


The lens is designed to sit close to your eyes i believe.
At first i had it further and i could see double if i looked down and over.
I was catching the lens edge in my vision because it was too far from my nose bridge.

side note:
Electrical tape was added to my nose piece because of the bit of light that enters when using double foam.
Works well and worth the trade off for the super cushy "professional snowboard goggle feel". imo
If you chose to double up please try it without actually sticking it.....
then if you decide to go for it,
peel n stick it.

all finished.

please know ralph is doing the best he can to get all his orders out in a timely manner.
Mine arrived 1 week before estimated delivery.
Average wait after paypal submission is an estimated 3-41/2 weeks (to usa from germany)
(based on the time frame that my order came)

An updated note on performance...
i do notice the split down the center where the lenses are fixed together.
It is only when looking to the extreme right or left of the screen.
it is not that noticeable as usually looking that far left or right is just a glance to see whats far off to the sides as I'm flying.
worth the trade for better clarity and comfortable magnification.

Removal and cleaning of the RHO lens is easier than having to take both halves apart to access the stock lens for cleaning.
Once you know how and have done it a few times its a smooth removal and replacement. (use gloves)

RHO-Lens instructions


Thank you very much! Great job.
I have taken this hint to update my instructions and write it more precise.

Please note that in the meantime I have also improved the product, the packaging and the cleaning tissue!

Is there somebody out here who can make a nice youtube video about the installation? I will find a way to give you a big thank you.

This write up makes it sound like a pain in the butt to install, and that line down the middle could be a deal breaker for that price. And how do we stop the lint and dust from getting behind them? Hopefully someone will make an installation video.

They are not a pain to install or remove,
however there is a learning curve to installing them.

I chose to share my discovered method to make the curve a bit less.
These lenses are thick glass and tuned well. (in my opinion)
The pictures on his site of the different text comparisons gives a good example of the difference in clarity..

Ralph also offers a 14 day money back guarantee as long as they are not damaged.
I'm sure a video is in the works.
lint behind the lens happens yet I'm over it for the trade off.
Im just careful where i set the Headplays down when out of the case i have.
I can notice the center line if I'm looking as far right or left as possible.
yet with the wide view inside this is a rare occurrence.

these are my personal thoughts on the matters you address.
I personally like them for what they are at the price they are at.
Ralph is not endorsing me or giving me anything for this,
Its just me trying to help those that wish to know a bit more about one of many methods to install them.


I love your avatar!
one of the funniest and scariest movies i can remember watching as a child.

Is the picture quality difference as dramatic as his sample pic seems? I don't have any problem focusing with the stock lens, but am wondering if the quality difference makes it worthwhile. Thanks.

the lens that comes with the headplay hd is a plastic lens that uses ridges to change the light.
These ridges cause a definite blur that is noticeable when compared back to back with the glass RHO.
I have almost 20/20 vision.
I dont wear or need glasses.
I bought the lens for the clarity and less eye strain.
I got a nice dose of both with these.
I won't go back to the ridges again.

No, it's not that dramatic. It's possible to get a clear in-focus image through the Fresnel lens.
Yes, sometimes you see a hint of the Fresnel ridges, or a little Moiré effect, and the fact that you
don't see any of that in the left hand sifr of the comparison pic, means the camera wasn't focused right.
I don't doubt that these new lenses will be a significant improvement for folks with
middle aged eyes (like mine), but a comparison pic that misleading, bothers me.

Tron,

Don't sweat it. If some folks would bother to go to Ralph's site, they'd see that he's not making a direct comparison to exactly how the screen looks between the two. I took it as an example of the difference between someone like me looking at the HP screen without helpers, and then with the RHO-Lens.

Your discussion helped me decide to take the plunge and give them a try. Doesn't hurt that Ralph is offering a 14 day trial to see if they work for you.

Thanks,
Tinman

Thank you tronaton for this mini-howto, it helps me

I use double foam too and also have a bit of light that enters near the nose, it's quite anoying, I have to do something. Did you find a better solution than yout electrical tape ?

And thank you Ralf for this awesome lens. Is it not possible to make another shape that will fit perfectly, without any holes, to prevent dust on the screen ?

thanks tin, i just want to help.

I cut some of the foam at my cheeks with a sharp pair of scissors.
Remember they were not designed for double foam so were improvising.
I found that the most pressure when wearing them was at my cheek bones.
I reasoned that thats where i should shave a bit.. Ive been doing it little by little slowly.
It will be different for different faces yet just find the area where your face sticks out the most and remove a bit from that area. i took foam from the sides at an angle so as not to take away the fuzzy part.


it helps a bring the goggles closer yet still maintains the comfort.
