The large shift towards more women in optometry necessitates ergonomic reconsideration of tools, equipment and workstations, because of gender size differences. This study focused on the anthropometric component of ergonomics; 33 men and 33 women were measured for height and eight other parameters which may be important in equipment design. They were also asked if they sat or stood while performing an eye exam. The t-test comparison showed a very highly significant difference between genders for all parameters. Men's size made no difference in sitting or standing, whereas women's did. The level of significance was highest when comparing all subjects, which meant height, not gender, is the critical factor, especially for those on the shorter end. Equipment manufactures and designers should cater to a larger range of physical dimensions than in the past.
