Safilens releases new presbyopia lens

Safilens has launched the Open 30 Presbyo monthly silicone-hydrogel lens for presbyopia.

The new lens, like the fusion 1day presbyo daily, uses a patented afocal design where the lens is neither multi-focal nor progressive. Instead, it features a small hyper-refractive central area that keeps paraxial optical rays out of the retinal image.

The company said the afocal design increased the depth of field and consequently the width of the accommodation range and unlike a multi-focal lens which required a complex cerebro-ocular adaptation process, no adaptation time is needed, since simultaneous vision is not involved in the process.
