There is a difference in practical terms.

A VDL means that correction is required for, you guessed it, distance vision and for that the limitations means 'shall wear corrective lenses and have available a spare set of spectacles.

A VNL means that correction is required for near vision and for that limitation you need to have corrective lenses available and a spare set of spectacles available.

Thanks Frank...that explains why the code VNL is on my Class 2 medical (although to be fair my medical does state it in long hand). I had just not understood what VNL meant.
Thanks again

Abbreviation-phobia, I that a medical condition? :wink:

PeteSpencer wrote:A former forumite used to tell the tale of his first pair of varifocals which gave him great trouble judging the height of kerbs.

This culminated one day in mis-judging the sill while entering a London Underground train and flying headlong into the carriage to the bafflement of the other passengers.


Knowing PeteSpencer's former profession, I was rather expecting him to offer an alternative to any abbreviation beginning with "V" :thumright:

Is there a TLA for the eyesight problem where you can't see posts you know you've written?

I was serious about the question of replacement lenses to correct 'old eyes'. The joke was a harmless addition, only to be feared by humourless curmudgeons .

Both corrective surgery and interocular lenses replacements are allowed with some caveats.

Some more information here: ... lots-(EASA)/Conditions/Visual/Guidance-following-eye-surgery/

With regard to vanishing joking posts - consider that humour is a very personal matter and what you think is a funny joke may be nausea inducing to a humourless curmudgeon. We generally let you get on with your PAW promoting posts in EC threads but we don't quite need that in every thread on the forum.

Thanks for the first link.
I had had not realised the distinction between "have available" and "wear".
When VNL was initially put on my class 2, in practical terms "have available" meant the same as "wear" to avoid faffing around during the busier times of a flight.

Now that I dont optically need readers, I can revert to standard sunglasses and just have a couple of pairs of cheap supermarket readers in the "available" flight bag to satisfy the legal bit of paper.

The table also suggests my AME could have removed VNL from my Class 2 certificate to keep things simple!
