The eye scheme is a method of contraception that was developed in the 19th century by the German gynecologist Karl Friedrich Haase. This method was popular in Germany and Austria at the end of the 19th and beginning of the 20th centuries. It was based on the use of a special ring that was inserted into a woman's vagina and prevented the fertilization of the egg.
The eye scheme was very popular among women who did not want to use other methods of contraception. However, it had its drawbacks, such as the possibility of infections and vaginal injuries. Additionally, using the ring could lead to menstrual irregularities and other health problems.
Currently, the Glaze scheme is not used as a method of contraception, but its history continues to be interesting and important for the history of medicine. It shows how women fought for their rights and freedom of choice in matters of health and contraception.
