DESCRIPTION
AVAIRA (enfilcon A) Contact Lenses are available as spheric,
aspheric, toric and multifocal lens designs.
The lenses are made from a material containing 46% water and 54%
enfilcon A, a silicone-containing hydrogel. The lenses have a tint
(phthalocyanine blue) which is added to make the lens more visible for
handling. The lenses also contain a UV absorbing monomer which is
used to block UV radiation.

ACTIONS
When placed on the cornea in its hydrated state, the AVAIRA (enfilcon
A) Soft (Hydrophilic) Contact Lens acts as a refracting medium to focus
light rays on the retina. The toric lens provides a more even surface
over the highly uneven astigmatic cornea and thus helps to focus light
rays on the retina.
The thinnest AVAIRA (material) Soft (Hydrophilic) Contact Lens (-2.00
to -10.00 D) blocks 75% of UVA radiation and 99% UVB radiation
average across the spectrum. The radiation blockage of the AVAIRA
lens will increase for thicker lenses (Please refer to accompanying
transmittance curve graph).

crystalline lens of a 25-year-old person.
WARNING: UV-absorbing contact lenses are NOT substitutes for
protective UV absorbing eyewear, such as UV absorbing goggles
or sunglasses because they do not completely cover the eye and
the surrounding area. You should continue to use absorbing
eyewear as directed.
Long term exposure to the UV radiation is one of the risk factors
associated with cataracts. Exposure is based on a number of
factors such as environmental conditions (altitude, geography,
cloud cover) and personal factors (extent and nature of the
outdoor activities). UV- absorbing contact lenses help provide
protection against harmful UV radiation. However, clinical studies
have not been done to demonstrate that wearing UV-absorbing
contact lenses reduces the risk of developing cataracts or other
eye disorders. Consult your eye care practitioner for more
information.
INDICATIONS FOR USE
Spherical and Aspherical
AVAIRA (enfilcon A) SPHERE and ASPHERE Soft Contact lenses are
indicated for the correction of ametropia (myopia and hyperopia) in
aphakic and non-aphakic persons with non-diseased eyes in powers
from -20.00 to +20.00diopters. The lenses may be worn by persons
who exhibit astigmatism of 2.00 diopters or less that does not interfere
with visual acuity.
Toric
AVAIRA (enfilcon A) TORIC Soft Contact lenses are indicated for the
correction of ametropia (myopia or hyperopia with astigmatism) in
