Changing light conditions

While good visual acuity is essential, it is important to keep in mind that a combination of other factors can also affect patients’ satisfaction with their vision.1


The 3 key factors that contribute to patients’ level of vision satisfaction are1:

  • Visual endurance—a measure for the expectation of seamless vision across tasks and over time
  • Discriminating vision—the 4 critical capabilities of the visual system include resolution, chromatic contrast sensitivity, motion detection threshold, and stereoacuity
  • Spatial vision—the perception of spatially defined features in the surrounding environment


Why visual endurance may be of particular importance to patients1

  • Despite having excellent Snellen visual acuity, many soft contact lens wearers report fluctuating and declining overall satisfaction during the day
  • In a survey sent to their smartphones every 2 hours, 62% of existing reusable and daily disposable soft contact lens wearers participating in the study experienced a decline in:
    • Comfort
    • Overall lens satisfaction
    • Vision quality over the course of the day


Managing visual endurance1

Biological or environmental factors triggering a change in vision quality are typically perceived as an inconvenience or discomfort.

If we are truly to satisfy our patients, we need to explore new product innovations and expand our metrics and assessments to include the 3 dimensions of vision satisfaction:

  • Visual endurance
  • Discriminating vision
  • Spatial vision


Talking with patients

By understanding the factors that make up vision satisfaction, you can help patients make more informed decisions during the fitting and follow-up process. The next time you are talking to a patient about their contact lens needs, be sure to let them know that:

  • A lens that adapts to changing light conditions could make a difference
  • Glasses are not the only option for adapting to changing light conditions. In 2019, contact lenses will be available, too
  • Their lifestyle could be enhanced with a contact lens that reduces the stressful impact light can have on their eyes2
  • ACUVUE® OASYS with Transitions™ Light Intelligent Technology™ is the first-of-its- kind contact lens3 that seamlessly adapts to changing light, providing all-day soothing vision2,4*
