Introduction: There are two main types of visual deficit - blindness and low vision. It depends on the decrease of the vision of the better seeing eye after correction. Low vision is a condition of visual acuity, even after treatment and correction, of less than 6/18 or a visual field of less than 10 degrees.

The aim of this study is to investigate the awareness of blindness and low vision in the general population and among the health care professionals.

Materials and Methods: This is a questionnaire survey. The study was performed from 10 April 2018 to 10 May 2018 in Varna. We used a separate questionnaire for the two groups of participants. Тhe first group consisted of randomly chosen patients in the Eye Center  and their relatives and the second included medical specialists. The statistical analysis was made with Microsoft Excel 2013.

Results: The majority of respondents - 60% were between 25 and 60 years old. More than 89% of the respondents had no information about the activities of the Union of the Blind and the special schools for blind children in Varna and in Sofia. Over 33% of respondents were not interested in specialized training in visual rehabilitation, 75% did not know the prices of the devices for correction of low vision. This matter was interesting for 91% and 83% would take place a National Vulnerable Campaign for low vision. 

Conclusion: The awareness of blindness and low vision among the general public and the medical specialists is very unsatisfactory. This indicates the need for change of public opinion and for specialized training of medical specialists. Therefore, an implementation of a low vision algorithm is needed.
