Wearing Restrictions and Indications

1-Day Acuvue Define (etafilcon A) Contact Lenses (spherical) are indicated for daily and extended wear for the correction of refractive ametropia (myopia and hyperopia) in aphakic or not-aphakic persons with non-diseased eyes who may have 1.00D or less of astigmatism and/or enhance or alter the apparent color of the eye for lenses with cosmetic tint.

1-Day Acuvue Define (etafilcon A) UV Blocking Contact Lenses help protect against transmission of harmful UV radiation to the cornea and into the eye.

The 1-Day Acuvue Define (etafilcon A) Contact Lenses described in this booklet may be prescribed for either daily wear or extended wear from 1-7 days between removal as recommended by your Eye Care Professional. They should be removed from your eyes and discarded as prescribed by your Eye Care Professional.

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 surrounding area. You should continue to use UV absorbing eyewear as directed.

Note: Long-term exposure to 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 outdoor activities). UV blocking contact lenses help provide protection against harmful UV radiation. However, clinical studies have not been done to demonstrate that wearing UV blocking contact lenses reduces the risk of developing cataracts or other eye disorders. Consult your Eye Care Professional for more information.

Instructions for Presbyopic Patients (Monovision)

You should be aware that, as with any type of lens correction, there are advantages and compromises to presbyopic contact lens correction. The benefit of clear near vision in straight ahead and upward gaze that is available with 1-Day Acuvue Define (etafilcon A) Contact Lenses for Monovision may be accompanied by a vision compromise that may reduce your visual acuity and depth perception for distance and near tasks. Some patients have experienced difficulty adapting to this. Symptoms, such as mild blurred vision and variable vision, may last for a brief period or for several weeks as adaptation takes place. The longer these symptoms persist, the poorer your chances for successful adaptation. You should avoid visually demanding situations during the initial adaptation period. It is recommended that you first wear these contact lenses in familiar situations that are not visually demanding. For example, it might be better to be a passenger rather than a driver of an automobile during the first days of lens wear. It is recommended that you only drive with Monovision correction if you pass your state drivers license requirements with Monovision correction.

• Some presbyopic patients require supplemental spectacles to wear over the 1-Day Acuvue Define (etafilcon A) Contact Lenses for Monovision to provide the clearest vision for critical tasks. You should discuss this with your Eye Care Professional.
• Some presbyopic patients will never be fully comfortable functioning under low levels of illumination, such as at night. If this happens, you may want to discuss with your Eye Care Professional having additional contact lenses prescribed so that both eyes are corrected for distance when sharp distance binocular vision is required.
• It is important that you follow your Eye Care Professional's suggestions for adaptation to presbyopic contact lens correction. You should discuss any concerns that you may have during and after the adaptation period.
• The decision to be fit with Monovision correction is most appropriately left to the Eye Care Professional, in conjunction with you, after carefully considering and discussing your needs.
