However, the effectiveness and the durability of binoculars can only be achieved if proper care and maintenance is observed.

The Impact of Dirty Binoculars on Performance

Your enjoyment of the view through binoculars can be unpleasantly altered, if the binoculars are dirty. Dirty optics can significantly reduce the performance in several practical ways:

The presence of dust, dirt, and/or fingerprints on any of the lenses will scatter the light and result in reduced clarity over the picture. This causes difficulties in recognizing details or colors which are usually very fine.

2- Light Transmission

The images would be also darker and less colorful because some greasy substance that is present in both outer and inner surfaces of the lenses limits the light passing. Such an issue becomes even worse when the surroundings are dim.

3- Increased Glare

Dirt smears and greasy residue figures on the front surface of eyepieces may create reflections and glare that were not intended especially when the viewing apparatus is under bright sunlight or close to the light source.

4- Eye Fatigue

There are times wherein the end-user attempts to look through the binoculars even when they are dirty, which results in the user experiencing tired eyes and eye strain that can lead to headaches especially when prolonged.

Bits of dirt including sand or grit if not clean can cause abrasion on the coatings of the lenses and this will eventually lead to serious damage to the lenses of your binoculars.
