Increased rigidity or stiffness has some advantages in that the lenses handle very well and are a perfect choice for people who exhibit poor handling capabilities. CooperVision Proclear toric has a proven track record of providing outstanding vision health and comfort. The researchers asked study participants to use CIBA Vision AOSept Plus in the United Kingdom or Clear Care in the United States with their test lenses wearing the lenses with daily removal and four-week replacement.
Proclear toric lenses feature a soft low modulus. Table 2 provides a list of commonly available commercial lenses and their main composition. Tetrafilcon 90 435 HEMA MMA NVP.

And they were designed to remain hydrated helping them feel moist and comfortable all day long. The modulus is defined as the force per unit area required to produce a deformation or in other words the ratio of stress to strain. Proclear toric lenses feature a soft low modulus that helps reduce the risk of adverse effects on the cornea.
