Purpose
Height (mm)

• Pre-presbyopes who frequently perform intense
  visual tasks often report ocular fatigue.
• This study evaluated the performance of
  single-vision spectacle lenses with a 0.6 D add
  for reducing visual fatigue and enhancing quality
  of vision and patient satisfaction in
  pre-presbyopes.

Methodology

• Study participants were recruited via print
  advertisements and during office visits at two
  sites the University of Alicante (Alicante,
  Spain) and the Institut et Centre dOptométrie
  (Bures-sur-Yvette, France).
• The Anti-Fatigue lenses were evaluated using
  questionnaires completed at dispensing and after
  2 and 4 weeks of wear.

5
Patient Population

• 103 pre-presbyopes ages 3543
• 68 had previously worn single vision lenses
• 35 were new to lens wear

For previous lens wearers, the Anti-Fatigue
lenses provided the same distance correction (
0.5 D) as patients previous lenses.
6
Overall Satisfaction

• Study participants reported a high level of
  satisfaction with their Anti-Fatigue lenses.

Not satisfied
Very satisfied
Also, 88 of wearers considered the adaptation
period Somewhat short to Very short, and 86
found adaptation Somewhat easy to Very easy.
7
Satisfaction with Vision

• The vast majority of study participants were
  satisfied with their visual comfort and quality
  of vision (dynamic, distance, intermediate, and
  near).

8
Quality of Vision for Specific Tasks

• Study participants were also highly satisfied
  with their quality of vision for specific tasks.

9
Comparison with Previous Lenses

• Overall, 78 of study participants who had
  previously worn single-vision lenses preferred
  their Anti-Fatigue lenses.
• Anti-Fatigue lenses were also preferred for
  several components of vision.

Future Lens Wear

• 92 of wearers said they planned to continue
  wearing their Anti-Fatigue lenses, either for all
  activities or for specific tasks.
• A majority of patients said they would wear their
  Anti-Fatigue lenses for specific tasks, including
  high-precision near work, computer use, and
  reading/writing.

Conclusion

• Lenses with a 0.6 D add can reduce visual
  fatigue among pre-presbyopes, enhancing visual
  comfort as well as dynamic, distance,
  intermediate, and near vision.
• Among study participants, including both previous
  single vision lens wearers and new spectacle
  wearers, 87 of wearers preferred Anti-Fatigue
  lenses to their previous situation.
