TopVue Bi-weekly contact lenses are comfortable hydrogel lenses with added sodium hyaluronate that ensures extraordinary moisture and all-day comfort. These lenses have a 14-day replacement schedule.
TopVue BiWeekly are comfortable, hydrogel lenses produced with two effective lubricants: sodium hyaluronate and the PEG (polyethylenglycol) wetting agent, both of which ensure extraordinary moisture and maximum all-day comfort. Sodium hyaluronate, or hyaluronic acid, is a substance natural to the human body. Besides joints and other body parts, it can be found in the vitreous humour, which is the gel-like substance that makes up the eyeball. The parameters of TopVue contact lenses suit 99% of users.
TopVue contact lenses are designed with exceptionally thin edges to reduce friction between the lens and the eyelid during blinking. The eyelid comes into contact with the lens edge whenever we blink. If the edge is thick, we are aware of the presence of the lens in our eye. Although a seldom-discussed factor, the lens edge is a decisive factor for lens comfort.
TopVue Biweekly contact lenses feature stable optical correction technology to achieve the same dioptric power within the whole optical zone. Thanks to this, the lenses provide high-quality vision in any light conditions.
TopVue contact lenses are equipped with UV filters that absorb harmful UVA and UVB radiation. However, as the lens covers only a small part of the eyeball, it is still necessary to wear sunglasses outdoors to protect the entire eye area from sun damage.
The advanced AQUAMAX technology uses a new method of applying the UV filter in the production of contact lenses, a method that has no negative impact on their properties. TopVue contact lenses have thus acquired better mechanical qualities for application (better handling) and comfort.
TopVue contact lenses are not intended to be worn during sleep. At the end of the day, they must be removed, disinfected, and stored in a cleaning solution for the night. Each pair should not be worn longer than 14 days from first use.
The lenses are made from Etafilcon A hydrogel material and contain 58% water. Their oxygen permeability is declared to be 26 Dk/t.
