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.

ACTIONS

When placed on the cornea in its hydrated state, the lenses act as refracting media to focus light rays on the retina. The UV absorbing monomer in the lenses are used to block UV radiation. The average transmittance characteristics are less than 5 % in the UVB and less than 50 % in the UVA.

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-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

The lenses are indicated for daily wear for the correction of refractive ametropia (myopia or hyperopia) in aphakic and not- aphakic persons with non-diseased eyes. The lenses may be worn by person who exhibit astigmatism of 2.00 diopters or less that does not interfere with visual acuity.

The lenses help protect against transmission of harmful UV radiation to the cornea and into the eye.

The eye care professionals may prescribe the lens for single use daily disposable or daily wear in a Frequent Replacement Program. As prescribed for single use daily disposable wear, patients are instructed to dispose of the lens at each removal. As prescribed for planned replacement, lenses should be cleaned, rinsed, and disinfected each time they are removed. The lens should be disinfected using a multi-purpose (contact lens disinfecting) solution or hydrogen peroxide disinfecting systems.

CONTRAINDICATIONS (REASONS NOT TO USE)

Do not use the lenses when any of the following conditions exist:               

  • Acute and subacute inflammation or infection of the anterior chamber of the
  • Any eye disease, injury, or abnormality that affects the cornea, conjunctiva, or
  • Corneal hypoesthesia (reduced corneal sensitivity), if not
  • Any systemic disease that may affect the eye or be exaggerated by wearing contact
  • Allergic reactions of ocular surfaces or adnexa that may be induced or exaggerated by wearing contact lenses or use of contact lens

WARNINGS

Patients should be advised of the following warnings pertaining to contact lens wear:

  • Problems with contact lenses or lens care products could result in serious injury to the

Patients should be cautioned that proper use and care of contact lenses and lens care products, including lens cases, are essential for the safe use of these products.

  • Eye problems, including corneal ulcers, can develop rapidly and lead to loss of
  • Studies have shown that the risk of ulcerative keratitis is greater for extended wear contact lens users than for daily wear
  • When daily wear users wear their lenses overnight (outside the approved indication), the risk of ulcerative keratitis is greater than among those who do not wear them overnight.
  • The overall risk of ulcerative keratitis may be reduced by carefully following directions for lens care, including cleaning the lens case.
  • Studies have shown that the risk of ulcerative keratitis among contact lens users who smoke is greater than among non-smokers.
  • If patients experience eye discomfort, excessive tearing, vision changes, redness of the eye or other problems, they should be instructed to immediately remove their lenses and promptly contact their Eye Care It is recommended that contact lens wearers see their Eye Care Professional routinely as directed.
  • The wearing of the contact lens while sleeping increases the risk of infection and permanent damage to vision.
  • The tinted contact lens can reduce visibility in low light conditions.

PRECAUTIONS

Special Precautions for Eyecare Professionals:

  • The eye care practitioner should consider all characteristics of the lens that can affect lens performance and ocular health, including oxygen permeability, wettability, central and peripheral thickness, and optic zone
  • The potential impact of these factors on the patient’s ocular health should be carefully weighed against the patient’s need for refractive correction; therefore, the continuing ocular health of the patient and lens performance on the eye should be carefully monitored by the prescribing eye care
  • Fluorescein, a yellow dye, should not be used while the lenses are on the eyes. The lenses absorb this dye and become discolored. Whenever fluorescein is used in eyes, the eyes should be flushed with sterile saline solution that is recommended for in-eye
  • The eyecare professionals should instruct the patient to remove the lenses immediately if the eye becomes red or
  • The patient should be instructed to always discard disposable lenses and lenses worn on a frequent/planned replacement schedule after the recommended wearing schedule prescribed by the eyecare
  • The lenses are prescribed for disposable wear, and are to be disposed of once they are removed from the patient’s eye. It is important that patients be instructed to always have available a pair of replacement In the event that a lens must be removed from the eye because of dust, a foreign body or other contaminant gets on the lens or the lens becomes dehydrated, the lens should be removed and replaced with a replacement lens.
  • Be sure that before leaving the eye care professional’s office, the patient is able to remove lenses promptly or have someone else available to remove

  • Iritis.

If the patient notices any of the above, he or she should be instructed to:

IMMEDIATELY REMOVE THEIR LENSES AND CONSULT AN EYE CARE PROFESSIONAL BEFORE RESUMING USE.

When any of the above problems occur, a serious condition such as infection, corneal ulcer, neovascularization, or iritis may be present. The patient should be instructed to keep the lens off the eye and seek immediate professional identification of the problem and prompt treatment to avoid serious eye damage. The patient should bring their lenses, solutions and lens case with them to their eye care provider for culturing in order to better establish the identity of any organism associated with the patient’s infection.

FITTING

Conventional methods of fitting contact lenses apply to the lenses.

INSERTING THE LENS

  1. Wash, rinse, and dry your hands
  2. Place the lens on the tip of your index Check the front and back of the lens to ensure that the lens is worn correctly.
  3. Place the middle finger of the same hand just under your lower eyelashes and gently pull down the lower lid.
  4. Use the middle finger of the opposite hand to gently lift the upper
  5. Place the lens gently on the
  6. Release the eyelids gently and The lens will automatically center itself.

REMOVING THE LENs

Always remove the same lens first.

  1. Wash, rinse, and dry your hands
  2. Always be sure that the lens is in the correct position on your eye before you try to remove it (a simple check of your vision, closing one eye at a time, will tell you if the lens is in the correct position). Look up and slowly pull down your lower lid with the middle finger of your removal hand and place your index finger on the lower edge of the lens. Squeeze the lens lightly between the thumb and index finger and remove Avoid sticking the edges of the lens together.
  3. Remove the other lens by following the same procedure.
  4. Follow the required lens care procedures described under the heading LENS CARE
  5. Note: If this method of removing your lens is difficult for you, your eye care professional will provide you with an alternate method.

LENS REPLACEMENT / WEARING SCHEDULE

The wearing and replacement schedules should be determined by the eye care practitioner. Patients tend to over-wear the lenses initially. The eye care practitioner should emphasize the importance of adhering to the initial maximum wearing schedule. Regular checkups, as determined by the eye care practitioner are also extremely important.

Studies have not been conducted to show that the lenses are safe to wear during sleep, therefore patients should be advised to remove their lenses while sleeping. Normal daily wear of lenses assumes a minimum of 6 hours of non-lens wear per 24-hour period.

The lenses are indicated for daily wear. The below maximum suggested wearing time mainly recommended for people who wear soft contact lenses for the first time.

    • After cleaning and rinsing, to disinfect, carefully follow the instructions accompanying the disinfecting solution in the eye care regimen recommended by the lens manufacturer or the eye care practitioner.
    • When using hydrogen peroxide lens care systems, use ONLY the lens case provided with the hydrogen peroxide care This case is specially designed to neutralize the solution. Failure to use the specialized case will result in severe stinging, burning, and injury to the eye. Follow the recommendations on the hydrogen peroxide system labeling exclusively. Following disinfection with a peroxide system, the lenses should be rinsed with sterile saline.
    • Thoroughly rinse lenses with a fresh solution recommended for rinsing before inserting and wearing, or follow the instructions on the disinfection solution
    • Do not heat the disinfection solution and
    • Leave the lenses in the unopened storage case until ready to put on the
    • CAUTION: Lenses that are chemically disinfected may absorb ingredients from the disinfecting solution which may be irritating to the A thorough rinse in fresh sterile saline solution prior to placement in the eye should reduce the potential for irritation.

    CARE FOR A DRIED OUT (DEHYDRATED) LENS

    If any lens is exposed to air while off the eye, it may become dry and brittle. In this event, simply dispose of the lens and replace with a fresh one.    

    CARE FOR A STICKING (NONMOVING) LENS

    If the lens sticks (stops moving or cannot be removed), the patient should be instructed to apply 2 to 3 drops of the recommended lubricating or rewetting solution directly to the eye and wait until the lens begins to move freely on the eye before removing it. If non-movement of the lens continues more than  5 minutes, the patient should immediately consult the eye care practitioner.

    EMERGENCIES

    The patient should be informed that if chemicals of any kind (household products, gardening solutions, laboratory chemicals, etc.) are splashed into the eyes, the patient should: FLUSH THE EYES IMMEDIATELY WITH TAP WATER AND IMMEDIATELY CONTACT THE EYE CARE PRACTITIONER OR VISIT A HOSPITAL EMERGENCY ROOM WITHOUT DELAY.

    HOW SUPPLIED
