Understanding BLINK STABILIZED® Design in Toric Contact Lens Prescribing

This is a sponsored post by Johnson & Johnson Vision Care, Inc., a supporter of NewGradOptometry & new graduate optometrists!


We all have had astigmatic patients who’ve complained about blurred or fluctuating vision when wearing their contact lenses.

This complaint may stem from a variety of factors including:

  • Interaction of eyelids with the lens upon blinking
  • Rotational stability of the lens
  • Lens shifting during rapid head movements
  • Binocular vision disturbance from induced prismatic effect

All of these factors can impact visual outcome and should be considered when it comes to toric contact lens prescribing.

Understanding these forces involves observation of anatomical variation between patients and clinical examination with focus on lid position, globe interaction, aperture size, and the effect of blinking on contact lenses.

There are several current toric contact lens designs:

  1. Prism Ballast Lenses that have a thin apex and thick base.
  2. Peri-Ballast Lenses that have peripheral ramp angles and a thick inferior ballast.
  3. Dual Thin Zone Lenses that have sharp junctions between thick and thin zones.
  4. BLINK STABILIZED® Design Lenses

Prism and Peri-Ballasted Lenses:

These lenses are gravity dependent and can be challenged by eye and head movements outside central or straight-ahead viewing.

These particular lenses have shown to rotate about 2.5 times more than other designs like BLINK STABILIZED® Design lenses.1

Rotational instability can impact visual comfort and clarity of vision in patients.

Another major factor to consider is the induction of vertical prism.

screen-shot-2016-11-11-at-3-29-48-pmContact lenses that rely on prism or peri-ballast design, can induce or create prism within the optic zone.

A study was conducted measuring the mean vertical prism 
in the central 6.0mm zone of eight commercially available soft toric lenses.2

This study showed that unlike lenses with BLINK STABILIZED® Design which had virtually no vertical prism, these other lenses with prism or peri-ballast design had mean vertical prism ranging from 0.5∆ to 1.2∆.2

How is BLINK STABILIZED® Design different?

BLINK STABILIZED® Design is present in 1-DAY ACUVUE® MOIST Brand Contact Lenses for ASTIGMATISM and ACUVUE OASYS® Brand Contact Lenses for ASTIGMATISM and works to mitigate these factors which can impact the success of contact lens wear in our astigmats.


  • Employs lateral thickness gradients
  • Is designed to realign when lens moves off axis
  • Contains no prism in optic zones
  • Has an overall thinner profile than ballast design lenses
  • Has four “active zones,” or points of stabilization on the outer central periphery and a minimal pressure zone under each lid

 This unique design:

  • Allows lenses to settle in just 3 minutes
  • Facilitates stabilization during blinking due to symmetrical weighting and is resistant to eye/head movements
  • Is present in all ACUVUE® Brand Lenses for ASTIGMATISM which provides clinicians a wide range of parameters, modalities, and materials to meet the needs and lifestyle of patients

By allowing these patients to avoid visual discomfort and inconsistent vision, you as a clinician can provide a better contact lens wearing experience and improve patient satisfaction.

Important Safety Information:

ACUVUE® Brand Contact Lenses are indicated for vision correction. As with any contact lens, eye problems, including corneal ulcers, can develop. Some wearers may experience mild irritation, itching or discomfort. Lenses should not be prescribed if patients have any eye infection, or experience eye discomfort, excessive tearing, vision changes, redness or other eye problems. Consult the package insert for complete information. Complete information is also available from Johnson & Johnson Vision Care, Inc., by calling 1-800-843-2020 or by visiting
