VISION THREAD (other than colour vision)

[ACIDO]

It's strange: the CAA Guide refers only to EASA document published 25.11.11 and doesn't mention any way the document published 15.12.11 that introduces refraction limits again...:rolleyes:

Hi Guys,

Just looking for some advice. I had a lazy eye (amblyopia) when I was younger but had it surgically corrected at age 7. I went to Specsavers a few months ago to get my eyes tested and asked her to test me up to Class 1 medical standard. In my right eye I had 6/9 and left eye 6/5. Everything was going fine but then she proceeded to project numbers up on to the screen and I could only see one number on the screen when there was meant to be two numbers and she proceeded to tell me I have monocular vision. She then did another test where she put a pen out to my right handside and asked me to focus on her nose and tell her when the pen starts moving and I passed that fine.

I'm just wondering what tests are conducted by the CAA to test your binocular vision?

Will I be automatically ruled out from getting a class 1 due to my medical history of having a lazy eye and the fact I then had surgery?

I've tried searching the CAA website but couldnt find any concrete answers to my questions and I was hoping to learn from you guys with your vast amounts of experience.

Thanks alot in advance,
Jack

Thanks for the reply I'm going to get in contact with the CAA in the coming days and see what they say. And just to add I can see fine out of both eyes individually with left eye being 6/5 and right eye being 6/9 and think my visual field are ok like I could see something approaching from my right side but not in as much detail as from my left side. But both eyes individually are near perfect.

Does anybody know what tests are conducted in the CAA class 1 to test visual fields?

For an FAA class 1 medical, you have to achieve 6/6 vision in each eye separately either with or without glasses. So I doubt that using the FAA route to get around things will help in your case.

In the UK CAA tests, you will not be subjected to reading numbers on the chart. If my memory is still sharp enough, you only do the letters reading at an actual 6 meters (not projected on a mirror or any computer device that makes it equate to 6 meter distance). One eye at 6/9 is the limit for class 1 medical. Amblyopia should not disqualify you for class 1 medical as long as you achieve 6/9 visual acuity in the amblyopic eye and the divergence/convergence is within limits.

The visual field test is done in a very conventional way. The eye specialist will hold a pen between his fingers and fully extend his arm to make the pen barely seen at the edge of your peripheral visual field at about 1 meter away while you look straight ahead of you. Then he will alternate between either shaking the pen lightly with his fingers or just keeping it stationary, and you have to tell him when it's either "moving" or "stationary". He will repeat the procedure several times at different angles around each eye separately. If you pass this one, you will be fine for the visual field test. If not, you will have to do a computer-based test (there are many different versions of it and I'm not sure which one they do use in the CAA).

I hope this helps somehow.


Good luck.

H i everybody,

I need some advice. Last November I did my class 1 medical , but sadly I failed the exam because my astigmatism being 2.5 diopters in my left eye and the maximum initial being 2.0.
I then heard I could be eligible for a class 1 deviation with the CAA, when I emailed them they confirmed that I could indeed get a deviation, but told me that the new EASA regulations would be coming in from April ,so I decided to wait to see the situation was, because I didn't want to start training and be told I had my deviation taken off me.
Now that it is April I'm left in a situation where i am unsure what my options are(if any),is the deviation system completely gone for new applicants ,leading up to April I heard rumors that the initial astigmatism limit will be eased, is this true?
If anyone could give me some advice I would be very great full for the help.

Thank you.

Hello dear Ppruners!! and happy summer!

I'm seeking advice from airlinepilots that use contact lenses and/or glasses daily. I'm currently working as a flight instructor and I gotta say that I prefer to use my contact lenses instead of my glasses when I'm flying. But i started wondering, when flying the big jets at higher altitudes. How is it to fly with contact lenses, do they get dry quickly due to the thin air.

Any advice would be greatly appreciated :)

[Gudjon89]

which do you prefer ?? and why ??

[ramseyoptom]

My preference (having fitted c/ls for a few pilots) is a soft lens made out of Silicon Hydrogel material, most of these lenses are suitable for overnight wear and can be resistant to drying out.

Bausch & Lomb Purevision, Coopervision Biofinity, CibaVision Night & Day are all examples of this type of lens ( there are others on the market as well).
Another material that works well especially if dry eyes are a problem is Coopervision's Proclear, but it is not really suitable for overnight wear.

As with all internet advice see your eyecare practitioner for definitive advice.

Hi, I passed my Class 1 medical a couple of months back with the limitation that I shall wear corrective lenses. My left eye is fine, on my right eye I am -1.00.

They told me at Gatwick that I need to take care of getting the lenses myself. So now I have received a pair of glasses and some contact lenses that I am trying out at the moment. I will prefer to wear the contact lenses while flying.

Here is my question. They told me to take care of it myself and that I don't have to report back to them. But don't I need to prove to anyone that I have done so? Else I could just pretend that I am wearing contact lenses (not saying that I would)

Has anyone been in a similar situation?

[GolfLima]

You don't need to report back, it's presumed you're responsible enough!

[long final]

Echoed what I was about to say. Sounds like a Troll.

[BYR]

Definitely not a troll, it was a genuine question. But thank you!

[long final]

Well Ben apologies if I sounded harsh, it's just the question sounded very strange. If you need corrective lenses to comply with your medical cert why would you consider that someone might not use them?

[BYR]

Well, in my case my right eye is a bit weak and my left eye is fine. But I never notice any difference except when I'm holding my hand over my left eye. Personally I don't feel the need to wear glasses because I see just fine with both my eyes together.

So to me it feels a bit like I am wearing glasses for no reason. But obviously they gave me the limitation for a reason so I will accept it.

[GolfLima]

Fair play but better safe than sorry.

If you have a prang and you weren't wearing your glasses then you'll be pretty knackered...! :8

[Jerry Lee]

So, is the limit of astigmatism still -2,00 dioptres? May I have any chance to get a class 1 with an -3,00 dioptres of astigmatism in my left eye?

Another question: is it still possible to obtain a FAA CPL and then obtain a EASA class 1 medical certificate under renewal standards or is this route closed?

[michaelmedley]

Had my class 1 today and all was fine apart from ive got to go to park hospital Gatwick to see a specialist about my squint as they were unsure wether i may develop double vision in the future.

should i be worried or is this standard procedure??

any PMs would be highly helpful as would any replies from past experience.

Regard

Hey guys, I hold a JAA class 2 medical for my PPL, at the time I passed my skills test in 2006 I was -11 :eek: diopters. I had the medical issued with a deviation, and stipulated the usual must carry two pairs of specs etc.

Roll on to 2009, & I had succesful lasik to bring me back to perfect eyesight, and a further correction in Feb this year to make it 100% perfect again after slipping to -1 in my right eye only.

Now, I have 6/6 or 20/20 vision in both eyes, but suffer from monocularity. Will the new rules be worth investigating for the possibility of gaining a class 1 medical, or will I still be outside any chance of a class 1?

[WorldDC10]

I have a job opportunity requiring a JAA medical (I think UK CAA issued). I have held an FAA Class 1 for 15 years and have being flying Part 121 for the last 12 years but I from what I have read online I do not meet the eyesight requirements for a JAA Class 1 since I have more than +5 dioptres eyesight correction. I do correct to 20/15 or 6/5 with contacts and was wondering if it is possible to get a deviation based on my experience.

I plan to call the CAA tomorrow but just wondered if anyone on here had recent experience of this?

[outofwhack]

You would be best advised to lawyer up first.

[outofwhack]

If I was trying for a JAA medical the UK CAA would be the very last people on earth I would be talking to. Run boy run!

[Jerry Lee]

Is it true that the UK CAA will not be issuing EASA medicals until 17th September, 2012?
I heard they will issue JAR licence till 16th September, 2012 because 1st July, 2012 date turned out to not be achievable.
Can anybody confirm it?
