The reason I think glasses was my first opinion product ever invented. Is glasses, also known as eyeglasses or spectacles, are frames bearing lenses worn in front of the eyes. They are normally used for vision correction or eye protection. Safety glasses are a kind of eye protection against flying debris or against visible and near visible light or radiation. Sunglasses allow better vision in bright daylight, and may protect against damage from high levels of ultraviolet light. Other types of glasses may be used for viewing visual information or simply just for aesthetic or fashion purposes.
My second opinion on most important non-electronic product is books. Books are important because they give us insight into stories and lives we otherwise wouldn't be able to experience. A book also can help with vocabulary and grammar. It helps us to build our spirit, give information, helps to pass time, make us deeper in cultural, helps us to write and think better. We believe in the book for the communication of ideas, learning and as a source of pleasure and relaxation.
My last important product ever invented would be a bicycle. The benefits of bicycles have been tirelessly elaborated upon; bicycles improve health, ease congestion, save money, use less space, and provide efficient transportation with zero fuel consumption and zero carbon emissions. Bicycle is also a good use for exercising and keeps a person in shape.
These are my three most important non-electronic products. The reason I think glasses, books, and bicycles were important invention because we wouldn’t be the person we are today. We now have the ability to have that perfect vision and eye protection. To be able to learn on are own and have the education on books. And last thing is having a product that can benefit us from getting around places more easily.
