Product Information
The most effective way of cleaning optical lenses is with a specially formulated lens spray combined with an optical microfiber cloth. Use of cloth alone may result in scratching the lens coatings or surfaces. Care must be taken with the use of tissues that may be impregnated with perfumes or other chemicals that will leave a coatings on the lens resulting in smearing.
Lens Cleaning Solution
Lens Cleaning Solution
Quality lens cleaning solutions have particular characteristics. They are made up of water, surfactants, and a drying agent such as a small amount of alcohol.

Cleaning
Water alone will not clean the lenses because the surface tension of water inhibits the removal of grease and grime. To change the surface tension a very small quantity of surfactant is added. This causes the oil and dust to become suspended in the solution, allowing their removal without harming the lenses or sensitive optical coatings.
The quantity and type of surfactant is very important so as not to leave smearing on the lenses, as this will interfere with the visual clarity and also cause ‘starring’ or light flashes when looking into lights at night.
The surfactants we use have been carefully chosen to avoid such problems.

Fog particles are microscopic water droplets which diffuse light and make lenses appear cloudy. The addition of a hydrophilic surfactant allows the water droplets to relax by minimising their surface tension so they spread out across the lens, producing a smooth sheet of water. You can see through smooth water as you see through smooth glass. This smooth sheet of water is referred to as ‘wetting’, which is why surfactants are sometimes called ‘wetting agents’. The addition of a hydrophobic surfactant will reduce static electricity on the lens surface. This minimises the attraction of dust particles to the surface of the lens, keeping lenses cleaner for longer.
