I'm not flying the Europa yet, but regulary fly in a Cessna which has
Quote: | the instrument panel somewhat further away. The Europa is almost
finished, and sitting in the airplane and fiddling with some instruments
and imitating some portions of a flight (without making the sound )
I found out that changing focus between inside and outside is a bit slow
and uncomfortable. Never had any experience with glasses before, so
wondering what the best solution would be.

You will probably find that in strong light the aperture of your eyes

will close up and you almost won't need a lens to focus.

I have one eye almost useless, can't read with it. I find depthe
perception is a problem between 6" an 10 feet. Not necessary for flying
but usefull for taxi to judge wher the wing tips are.

Coming in late too this discussion, I have a Normal pair of Ray Bans (Green)with the Large lenses, In the bottom 1/4 I stick Optx Removable reading Lenses +2.00, These work really well for normal distance work looking through the top and you can adjust the Optx Lenses to suit your own needs to view the panel through thr bottom, It works for me

Frans,
Your experience sounds familiar. Sue and I found cheap bifocal sunglasses to be the best flying accessory we ever bought (from about £10 here and not very trendy to be honest, but I did buy some bifocal safety glasses in clear and tinted on the internet for much the same price and they looked fine) For us with the ability to focus close becoming more difficult with age they were the perfect soloution.
I'm no optician, but an optician friend approved them and reassured me that they would at least do no harm.
It would seem sensible to have a proper eye check to make sure you don't need anything more complicated, but then give the off-the-shelf bifocal sunnies a try before spending a lot of money on something more exotic.
Hope that helps you as much as it did us!
Cheers
Bill

I agree with Gary that this is the main issue with bifocals or progressive lenses: when looking over the nose during taxiing and take off (monowheel) and flaring (Monowheel and Trigear) you have no choice but to look through the reading portion of the lenses while you need to focus on "infinity". I do not think there is any 100% satisfactory solution to that problem. When I started to use reading glasses (I was not flying the Europa at this time) my only solution was to remove my glasses just before landing. A few years later I had to change my glasses again and I asked my optician to position the reading portion as low as possible. It is a lot better but again not 100% satisfactory . BTW I have been told that some airline pilots are using multifocals with two reading portions: the low one as usual and another one at the top of the lense for seeing the overhead panel! The distance portion of the lense is therefore reduced, but do they often need to see outside?

<<<<I'm not so keen on progressive lenses. I had some made a few years back and
took them up for a flight. Not being very tall I have to stretch my neck to
see over the glare shield. Everything went fine until I got into the
landing flare. As the nose of the plane went up to flare, I had to tip my
head back to see straight ahead. In so doing I was now looking through the
bottom of the lenses.......the "reading/magnifying" portion, which caused
everything to look blurry and fuzzy on the runway. Needless to say my
landing was more of an arrival than a landing. Thankfully I didn't break
anything. I took the glasses and threw them in the trash can.

Hi Everybody,
There are so many messages on this subject and I just havent had time to
read them all. If somebody has come up with this solution then please accept
my apologies for the duplication.
You can get bifocal sunglasses - the near vision is a reading lens and
clear - the far vision is brown or grey tinted. Cost approximately £15.00
sterling.
Have been using these for ages IMHO the perfect solution. I thought
everybody knew about these as they were advertised in the PFA magazine
(sorry LAA - its my age !!!)

Happy flying,
Carl Pattinson

Perfect! This is exactly what I'm looking for! Can just use my normal
sunglasses and put these stick on reading lenses at the right position,
without the need to explain everything to my optometrist and hope that
he will construct something usefull. And I can change it any moment
until it is perfect, or when the requirements of my vision change. It
looks like the perfect solution. Thanks!
