CooperVision Expands Parameters

CooperVision has expanded Avaira toric lens parameters with new +0.25D to +6.00D sphere powers to correct for hyperopia.

Approximately one-third of potential contact lens wearers require astigmatic correction. The newly expanded Avaira toric lens range now covers more than 90 per cent of astigmats.1

The Avaira brand is the only two-week lens to have polyethylene glycol (PEG) bound at the lens surface and throughout the interior. This compound tightly binds water, which helps maintain hydration and eliminates the need for rewetting agents.

Avaira lenses with Aquaform Comfort Science also incorporate a high level of oxygen transmissibility (125 Dk/t sphere, 91 Dk/t toric), rounded edges that promote minimal lid interaction, and a smoother lens surface.

The Avaira brand is the only two-week lens to have polyethylene glycol (PEG) bound at the lens surface and throughout the interior.

All Avaira toric lenses feature optimised lens geometry, uniform horizontal ISO thickness and wide ballast design, plus a larger toric optic zone. An ultraviolet radiation blocker helps protect wearers’ eyes, limiting 75 per cent of UVA and 99 per cent of UVB rays.
