If you don't see a difference between green and red for example, you can't pass the test because the colours are randomized everytime e. And the doctor doesn't tell you... here is the first round, here is the second one.

Question Becoming Reliant on Glasses

Hi Peeps,

I've been for an eye exam have been told that my vision is good although I do strain somewhat for reading and close up stuff. I do notice that I get tired when reading and have subsequently got glasses.

My glasses do help with the reading as a drive computers all day and wear my glasses for most of this time. When I remove these glasses to go home my eyes take a while to adjust, things are a little blurry for 10-45 seconds. I *think* this is getting worse (I have had the glasses 3-4 months now).

My question is, are the glasses damaging my eyes or am I going to become totally reliant on them. I have asked my optician who says that this is normal but when it is affecting my vision I want to do my due diligence.

Any thought out there?

Thanks
SB

FAA CPL, FAA Class 1, high myopia: will I have troubles in Gatwick?

Hi guys,
I am in a very strange situation right now.
I hold an FAA CPL, an FAA Class 1 Medical and my prescription is the following:

Right Eye:
-7.00 dioptres, 0.25 astigmatism, 180° axis

Left Eye:
-6.00 dioptres, 0.50 astigmatism, 160° axis

As you can see my right eye is 1 dioptre out of the limit (-6.00 is the limit) but obviously within the revalidation standards, since there are no myopic limits anymore for the renewal (read on the JAA and CAA website, 100% and more sure).
I would like to try to get my JAA Class 1 in Gatwick, hoping they could make me fit applying what the CAR themselves say:

"ICAO Licence holders
Existing licence holders (i.e., a current valid licence equivalent to the medical certificate for which they are applying e.g. CPL or ATPL for class1, PPL for class 2) from other ICAO states with appropriate demonstrated experience applying for initial issue of a JAA medical certificate will be assessed to the JAA initial standard. Those who fall outside the initial standard, but within the revalidation standard and subject to satisfactory assessment and appropriate limitations, may be considered for a long-term deviation, which will then be transferred to their JAA licence, when issued."


I really don't care about the deviation, I just would like to have opinions about the chances I really have of sorting it out there in Gatwick.

I really, really appreciate any advice guys, provided you know what you're talking about!

Thanks!

Hi guys,

First time poster here.... It's nice to know I'm not the only CVD out there - can't believe there's over 50 pages on this thread! I must admit I haven't had time to read them all yet. My story is I've been flying for 8 years in Australia, >3000 hrs with plenty of night and multi IFR time and I also hold a CASA Grade 1 multi engine instructor rating. I actually hold an ATPL too, but just can't legally use it.... up until now my Class 1 medical has always been restricted (1) Valid up to and including CPL and (2) Valid only in Australian airspace.

What I'm curious about though is that today my medical renewal arrived in the mail today and the restrictions have changed slightly.... It now states (1) Not valid for ATPL operations and (2) Holder does not fully meet requirements of ICAO Convention Chapter 6 of Annex 1.

Is this basically saying the same thing as what the restrictions have always previously been? The not valid for ATPL ops is self explanatory, but what about the Australian airspace only restriction? Does this mean I can now fly internationally using my CPL previleges? eg. be a SO/FO on international ops? Or maybe that's being a bit hopeful!

The whole CVD thing is extremely frustrating! I've done all the testing possible here in Australia including the signal lights test where I got 5/6 lights correct so this classed as a fail unfortunately. So looks like all my options have been exhausted for now unless anyone has got some other suggestions?

Thanks guys!

Hi all,

I have a problem with color vision and i'm planning to fly to the USA next month and do the FALANT. Does anyone know how much time i need if i have to request a SODA or medical flight?
I'm a bit worried about this because i don't have too much money and time.
I guess it doesn't matter in which state you do the test, i'm planning to fly to Oklahoma where it's LEFTSEAT company that help pilots with medical problems. Does anyone know if i'm in the right way?
Thank you all very much for this thread.

Daniel

Green deficiency

Hi all,

Does anyone know how to read/understand the Anomaloscope test results? For example, according to the Anomaloscope test, I have been diagnosed with Green deficiency. Left eye 19 and right eye 24. The test was done by a nurse and the hospital I took the test in is not recognised by The Aviation Authority in my country.
I know I need to take a test from an authorized hospital and I am also going to try and show these results to some of the Dr's in advance. But from people who have taken this exam and are experts at it, what could green deficiency 19 and 24 mean according to JAA rules?? PASS/FAIL

Regards

If the benchmark is 32 and the subject's score must be within 4 units of this benchmark, this means with left eye 19 and right 24 is a fail? is that correct ?
btw, are you certain of this information, is the benchmark 32 ?

What am I ??????????

Hi all,

I have two questions:

1. Can a person with Dichromat - Deuternanopia become a pilot? This means that the person is moderatley severe and one of the basic mechanism is absent. In this case because it is Deutermanopia, it is the Green pigment which is absent/missing.

2. Can a person be Dichromat - and at the same time be part Deuteranopia and part Deuteronomaly ?

The reason I am asking the second question is because, after I took the Anomaloscope test, my Dr said that I was Dichromat but at the same time Deuteranopia AND Deuternomaly. This does not make any sence because according to my research, for a person to be Deuternomaly, that person needs to be Anomalous Trichromacy(One of the 3 cone pigments are altered. It is inpairment rather than lost) NOT Dichromat.

Thanks for the answers in advance,

Regards

It all depends on how well they do on the tests, but generally I'd say it's no go. I have Deuteranopia and I was refused a Class 1 Medical.

2. Can a person be Dichromat - and at the same time be part Deuteranopia and part Deuteronomaly ?
I don't think so... it is my understanding that Deuteranopia means the absence of a cone that reacts to green wavelengths of light, while Deuteranomaly is just the impairment of that cone. I suppose it's possible to have say Deuteranopia and Propanomaly, but that would be bizarrely rare.

Iritis

Searched the whole thread but couldn't find anything.......

Does anyone know if a recurrent iritis/uveitis will prevent me from obtaining a Class 1? Haven't had an episode for about a year and vision is unaffected.

Regards,

CA

Iritis

Hi guys. I am a recurrent iritis sufferer. Last episode was about a year ago, and am wondering if anyone knows CAA policy on this with regards to a class1 medical? (for ATC). Any advice would be greatly appreciated.

Regards,

CA

Perhaps my condition is more rare than I originally thought. Has nobody out there got any experience of this?

Well I have never had it, but my wife had a very severe episode a few years ago. Very painful and she went blind in one eye. After applying steroids every hour, day and night, for 3 weeks her sight returned. Very very nasty indeed. I would have thought that there is usually an underlying reason why it appears and this might be a reason why a medical may be difficult. Speak to medical branch and they will advise. It is also more commonly called anterior uveitis.

Hi all,
nothing about this?
Come on, guys...I don't wanna think that nobody here has got the same problem of converting an FAA in a JAA being outside the JAA class 1 initial limits!

Hi all,

I am currently the holder of a JAR Class 2 medical.

I am looking at doing my ATPL theory soon, but my eyesight is preventing me.

My refractive dioptres are within the -6/+5 limit at +0.50L/+2.25R.

However the visual acuity is slightly out in my right eye. The limits for this are at least 6/9 in each eye separately and 6/6 both eyes combined.

My left eye is 6/5 however my right eye is 6/10 after correction. Together my eyes are corrected to 6/5.

I am looking into the possibilities that I have and one of them is LASIK. However, the CAA says that some aspects do not allow you to undergo corrective surgery to get you within the limits. Does anyone know if this applies to the initial refractive error (-6/+5) alone, or the visual acuity as well?

Shaun
