We began by finding parallel visual elements that relates to an optical clinic. The more recognizable symbols is the phoropter and the human eye. The dials on the phoropter are like the pupils of an eye.
The scientific symbol for "sigma" is σ. We wanted to incorporate all the visual elements into a cohesive symbol. Through many iterations, we found the our direction. Some of our drafts made the icon look mechanical; something that belongs in a car. This was not the right direction so we moved towards a solid, uniform shape. Our final design is a balance between "σ" with a phoropter and an eye.
We utilized the Golden Ratio as a reference when designing the proportions. When we design with level of intention, it brings together our style of design into the world.
