CE REGULATIONS
WHAT DOES THIS MEAN FOR YOU
Opticians are required to give patients information and advice on the correct use, care and limitations of their lenses. The information required is very specific and makes definite demands of opticians, particularly in terms of the restrictions on use of lenses. Much of it is information that any optician would give patients as a matter of course, but under the Directive, opticians are encouraged to do so systematically.
|
USAGE RESTRICTION
Driving
Lenses are deemed unsuitable for driving if light transmission is less than 8%, or if the tint affects the perception and recognition of traffic lights. For night driving, transmission should not be less than 80%.
Sun protection
The Directive defines five classes of sun protection, each with indications for appropriate use.
Lenses that leave distance vision uncorrected
These are not suitable for activities that require distance vision and are note recommended for driving. This applies principally to lenses designed for VDUs etc, which only offer mid and/or near vision correction.

Lens
care
Opticians must explain that lenses need regular cleaning by
washing with
soap and water or suitable lens cleaning
solution and drying
with a
soft clean cloth, and should advise when
solvents and
detergents should
not be used.
|
|
Glazing
Frames should carry the CE logo. If they were purchased
before June
1998, as in the case of reglazes, a disclaimer
form must be
sent with
the frames to be glazed, a copy of which is
obtainable from
Essilor.
