Prototype contact lenses ‘superior’

Researchers at Brien Holden Vision Institute have been developing novel contact lenses to slow the progression of myopia.

They have incorporated extended depth of focus (EDOF) principles to help enhance visual performance.

The researchers at Brien Holden compared the visual performance of two EDOF prototypes against two commercial contact lenses.

The study compared clarity of vision, ghosting, stability, driving vision and diurnal light changes, finding its EDOF prototypes to be ‘superior’ to the commercial lenses.

Senior research optometrist, Jennifer Sha, said: ‘What we found was that while the commercial lenses provided good high- and low-contrast visual acuity at all distances, the EDOF prototypes proved superior in the majority of subjective variables tested.
