Purevision Contact Lenses Visibility Tinted -4.00 BC/86 6 Units

PureVision2 contact lenses are high quality, super breathable extended wear contact lenses that can be worn for up to 29 nights if this wearing schedule is advised by your optician. Made from an ultra-breathable silicone hydrogel material, PureVision2 lenses allow three times more oxygen to reach the eyes than a traditional hydrogel contact lens. Designed to be worn for up to 29 nights consecutively, these lenses prioritise comfort for your eyes, allowing you to easily use them for hours at a time. Even in the most challenging environments, their unique design helps to stop them from drying out. This makes them ideal for anyone who spends long hours in front of a screen at work, or needs to concentrate on the road for a while. PureVision2 contact lenses are also designed to combat the common problem of spherical aberration. With traditional contact lenses this is the increased reflection of light that causes halo glares and vision to become blurred and unclear in certain light conditions. However with PureVision2 contact lenses this problem has been significantly reduced to give crisp, clear vision.
