When choosing circle lenses, the diameter of the coloured portion (the part of the lens with colour) is also important.
A larger diameter gives a bigger eye impression, while a smaller diameter creates a more natural eye appearance.
If the coloured diameter of the contact lens is too large for your eye size, it may result in an unnatural look with the whites of your eyes showing.
When using circle lenses for a subtle change in impression, consider the balance between the prescription’s DIA (diameter) and the circle lens’ coloured diameter before making a selection.
