Frequently Asked Questions about VEPLUS Eyeglass cleaner

Surely not, because the continual flow of liquid through the sponge produces a real self-cleaning of the sponge and keeps it in a perfect condition for further use.

The sponge of VEPLUS is made of a material that has some light sensibility which sometimes produces a slightly yellow colour of the sponge. This yellowish colour do not alter the physical properties of the sponge and therefore its function when cleaning keeps being the same.

Certainly not, and the explanation is very simple. For a material to scratch another it is necessary for its hardness to be higher than the hardness of the material to scratch, and also that both materials come into contact with a minimal required pressure. The sponge of the eyeglass cleaner VEPLUS cannot scratch neither the material of a lens (whether it is mineral or organic) nor its eventual coatings (anti-reflective, smudge-resistant or scratch-resistant) simply because the sponge is softer than any one of them. Furthermore, the sponge contacts the lens surface in a humid state and virtually without applying any pressure on the lens.

For these reasons it can be said with certainty that, concerning with the capability to scratch a lens coating when cleaning spectacles or eyeglasses, the sponge applicator of the lens cleaner VEPLUS does not make any difference with respect of the use of a conventional eyeglass cleaner in spray.

The safety of use of the VEPLUS sponge applicator is also confirmed by the millions of units supplied to professional opticians in the more than 20 years since its launching in 1989.

If after cleaning a pair of glasses with a cleaning solution, whether it is VEPLUS or any other lens cleaning solution in spray, the lenses got scratched, the most probable cause would be something as simple and as common as having wiped dry the lenses with a cloth that had fine dirt particles caught in it. Otherwise, the abrasive particles could have been already on the lens prior to the cleaning. In both cases, the scratching of the lens would have occurred at the time of wiping dry the lens; which is the time when the cleaning cloth gets firmly pressed against the lens. For this reason, to prevent scratching lenses when wiping dry, it is necessary first to remove any particle of abrasive dust that the lenses could have on their surface prior to the cleaning. Afterwards, following the application on the lenses of any spectacle lens cleaner solution or even water, a soft and free from abrasive particles cloth should be used for wiping dry the lenses.

The composition of VEPLUS eyeglass cleaner has a small alcohol content (lower to 5%) which, at the same it is inoffensive to lens materials and its coatings, it is necessary for effectively dissolving grease stains.

The VEPLUS eyeglass cleaner has some anti-static and anti-fog properties, but only to a degree that they have no adverse effect on the achievement of an effective, easy and fast cleaning. With higher anti-static or anti-fog properties the liquid would have an imbalance of performance, and its main cleaning properties would be spoiled.When a specific anti-static or anti-fog eyeglass cleaner solution is applied to a lens it leaves a residual film on the lens. At the same time that this film may achieve its purposes, it has some disadvantages such as:

a) Cleaning lenses takes substantially longer time and work due to the oily character of these products and their difficulty to leave lenses without stains from the liquid itself after use.

b) The residual film left on the lens by these products encourages light reflection after their use. Consequently, anti-fog products should not be used on lenses with anti-reflective coatings since they reduce and even nullify the purpose of the coating.

As some properties of a lens cleaner are opposite to each other and therefore they may not be held at the same time, one should choose the properties an eyeglass cleaner solution should have according to the product’s purpose. VEPLUS is formulated to solve the permanent and common problem of every eyeglasses user: the smudges and fingerprints on lenses, which are specially unpleasant with anti-reflective coatings.

Many lens cleaner products are labelled as “anti-fog” when, in fact, they do not have this property. These products are as anti-fog as VEPLUS is, just to a small extent, and therefore it is questionable that anti-fog capabilities should be claimed.
