Assessing your patients

A combination of probing questions and clinical tools can help you assess the impact of your patients' current lens wear and care routine on their ocular physiology. Asking specific questions may open the door for a more complete understanding of your patients' health and comfort.

Remember: their eyes might tell you what they don't

Clinical grading scales provide a means of standardised evaluation of key, comfort related physiological measurements, such as:1

  • Limbal hyperaemia

  • Corneal staining

  • Bulbar hyperaemia

  • Papillary conjunctivitis

Talk to your patients about your assessment – including how they score on comfort related physiological measurements – and help them understand the rationale for your recommended contact lens and wear-and-care routine.

There are two key ways to helping your patients stay healthy and comfortable in contact lenses:


The right lens

Refitting your patients' contact lenses may improve their ocular comfort. Advising patients of all available options helps them make more informed decisions.

A combination of probing questions and clinical tools can help you assess the impact of your patients' current lens and wear-and-care routine on their ocular physiology, and determine whether they might benefit from a transition to an alternative lens.

Proper lens care

Remind your patients that following simple wear-and-care rules can keep their eyes looking bright and healthy. Help your patients stick to your recommended wear-and-care routine by showing them the 'How to wear and replace your lenses' on the website.



Comfort you can see with ACUVUE® Brand Contact Lenses

Determine if your patients might benefit from a move to ACUVUE OASYS® contact lenses. A recent two-year clinical study has shown these lenses can improve key, comfort related conditions. The study evaluated the impact of ACUVUE OASYS® on ocular tissue, comparing baseline results against results at 24 months.2

The study included both established hydrogel and silicone hydrogel contact lens wearers (who switched to ACUVUE OASYS® from their habitual lenses) and non-wearers.



After two years in ACUVUE OASYS®, wearers experienced significant improvements in comfort related measures of ocular physiology.

Help for patients

Results showed reflect outcomes for the 42 established soft contact lens wearers completing the study. Reductions occurred in both incidence and severity. Images are for illustration purposes only, and do not reflect the grading scale used in the study.

  • Fundamentals of Presbyopia (CET)
  • C-76931. This course is accredited for non-interactive CET points for Optometrists (Communication, Contact Lenses) and Contact Lens Opticians (Communication, Contact Lenses) only.   Changing demographics, modern attitudes, more active lifestyles and the fact that many new presbyopes are existing contact lens wearers are all driving growing demand for a spectacle-free solution to presbyopia. This course consists of two modules which covers the fundamentals of presbyopia and reviews the correction options available. They serve to help you appreciate how little patients know about presbyopia and the vision correction options available. This course should take approximately 40-50 minutes to complete.
