Question: 1 / 400

Why should a camel hair brush be used on eyepiece lenses?

It reduces static electricity

It is soft and minimizes scratches

Using a camel hair brush on eyepiece lenses is advisable primarily due to its soft texture, which minimizes the risk of scratching the delicate surfaces of the lenses. The fine, soft bristles of a camel hair brush provide a gentle touch that is ideal for cleaning optical equipment without causing damage. This is critical in maintaining the integrity of eyepiece lenses, which can be easily marred by more abrasive cleaning tools.

While other options may present benefits for specific tasks—such as moisture absorption or ease of replacement—the central attribute that makes the camel hair brush a preferred choice in this context is its softness. This characteristic ensures a safe method of removing dust and debris without compromising the quality of the optical surface, thereby enhancing visibility and performance. Using a cleaning tool that does not scratch is essential in the field of optics, where precision is paramount.
