Optics glass disappoints for science education

This Industrial and Scientific product fails to impress .while the glass is circular and double-convex, it does not live up to expectations for science education purposes. The pros are that the glass does assist in some basic experiments, but the cons far outweigh them. The glass is cheaply made, causing issues with clarity and distortion. Additionally, the product arrived with scratches and other defects, making it unsuitable for classroom use..

Pros
  • Provides a clear and accurate magnification for scientific observation and experimentation.
Cons
  • Prolonged exposure to direct sunlight may cause damage to the eyes when viewing through the glass.

Great lenses and great seller!

These are high quality lenses, clear and clean! I also had questions about these lenses and the seller responded immediately and I am happy with the answer and the response!

Pros
  • Great for a small home
Cons
  • A dubious purchase for the elderly
