I have just spent two minutes finding this info, maybe have a search on the CAA website before posting a question...
I just cut a pasted the document but the doc can be found at...

and click on the link to JAR initial exam...
Best of luck.

JAR Class 1 (Professional Pilot) Initial Examination Visual Standards
These are the JAR Class 1 visual standards as applied by the UK CAA.
Distance Vision
Your visual acuity (measured by your ability to see, in this case, lines of letters on a chart at 6 metres)
must be at least 6/9 in each eye separately and 6/6 using both eyes together, with or without glasses or
contact lenses (correction). If you need correction the refractive error (the amount of correction) must
not exceed +5.00 dioptres of long sight or -6.00 dioptres of short sight. This is in the most ametropic
meridian (taking into account any astigmatism). Astigmatism must not exceed 2.00 dioptres. The
difference in correction between each eye (anisometropia) must not be more than 2.00 dioptres. Your
optometrist will be able to explain these terms.
Near Vision
On the standard near vision eye chart you must be able to read the N5 print between 30 and 50 cm and
the N14 print at 100 cm, with or without correction.
Contact Lenses
You may wear contact lenses as a professional pilot (but not to correct near vision). If you do wear
contact lenses, you should bring a report from an optometrist to your initial Class 1 examination, which
includes the following:
your contact lens specification and corrected visual acuity;
confirmation that you have worn your contact lenses constantly and successfully for over eight
hours a day over a period of at least one month.
All gas permeable and hard contact lenses must be removed at least 48 hours before the initial Class 1
medical examination. Any contact lenses should be brought to the examination. Multifocal contact
correction are not acceptable for lenses or monovision
Class 1 certification.
Refractive Surgery
The CAA does not recommend refractive surgery to gain a medical certificate to fly. The decision to
have this type of treatment must be between you and your eye specialist. In fact the certification limits
of eye correction with glasses and the limits of refraction before surgery are the same, so it is not
possible to gain a medical certificate by having refractive surgery, that you would not have obtained by
wearing glasses. However, if you have had refractive surgery, Class 1 certification will be considered
three months after a LASIK procedure, (provided an assessment including refraction has been carried
out at two months post-operatively). Certification can be considered six months after LASEK/PRK for
myopia (provided an assessment is carried out at three months post-operatively at Gatwick).
is usually possible one year after other types of operation. Please note that: Certification
the pre-operative refraction should not have been more than + 5.00 to -6 dioptres (applicants just
or advice.) outside this range should contact the CAA Medical Department f
an assessment by an eye specialist at Gatwick will be required
stability of refraction must be achieved. To show this you will need to obtain a report showing your
twick visit
you must have no problems with glare
Colour Vision
You will be tested for normal colour vision with Ishihara Test Plates (a series of numbers outlined by
different coloured dots, easily seen by someone with normal colour vision). If you fail these you will
need to pass an approved lantern test (a series of coloured lights that you must identify correctly) in
order to gain a JAR Class 1 certificate.
Eye Function
You must have normal fields of vision.
You must not suffer from double vision.
Any degree of heterophoria (eye muscle imbalance) in excess of:
8Δ exo, 10Δ eso or 2Δ hyperphoria - measured at 6 m
or
12Δ exo, 8Δ eso or 1Δ hyperphoria - measured at 33 cm
will require further evaluation by an eye specialist at Gatwick.
There must be no acute or chronic disease in either eye or surrounding structures.
