Johnson and Johnson presents contact lens study

Johnson & Johnson has published the findings of a study into eye and vision discomfort in contact lens wearers using visual display units. The company reported that those who wear contact lens are more likely than others to experience these symptoms.

Research by the company revealed that its new-generation silicone-hydrogel lenses (senofilcon-A) can lessen eye problems in contact lens wearers using computers. Of those previously reporting symptoms of eye discomfort tested with the new lenses, 88 per cent claimed an improvement of comfort, with 76 per cent reporting an increase in comfortable hours of wear.

Dr Jeffrey Anshel, author of Visual Ergonomics in the Workplace, said: “Research shows that while using a computer, we blink about three times less then normally. These long non-blinking phases can cause the surface of most contact lenses to dry out, which can lead to discomfort and a loss of visual clarity.”

The research has been published in the current issue of the peer-reviewed Eye & Contact Lens Journal.

Johnson & Johnson has in the past noted that 42 per cent of contact lens wearers use rewetting drops on their eyes to prevent feeling dryness during the day.
