They are very comfortable and well-tolerated hydrogel lenses with the addition of an extraordinarily effective lubricant – sodium hyaluronate and and the PEG (polyethylenglycol) wetting agent, which ensures 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.
TopVue Contact Lenses boast of very stable optical correction achieved by the same dioptric power within the whole optical zone. Thanks to this, the lenses provide high quality vision in any light conditions, which you will appreciate especially when driving in the dark.
TopVue Contact Lenses are, as one of the few, equipped with a UV filter absorbing harmful UVA and UVB radiation. It is of course always better if contact lenses possess a UV filter, but it is not 100% reliable as the lens covers only a part of your eye, and a bigger part of your white remains exposed to UV radiation. As a result, it is necessary to protect your eyes with sunglasses.
The 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.
Each pair of TopVue Daily Contact Lenses is intended for one wear only. They shouldn't be worn during sleep. They don't need to be cleaned, so you don't waste money on cleaning solutions. Accidental loss or damage to the lenses is not so financially painful.
The lenses are made of Etafilcon A hydrogel. They contain 58% water and their oxygen permeability is declared to be 26 Dk/t.
