Finally my review of the YH-301 GEO Twins Blue.
About these lenses I can only say how comfortable they are (as most GEO lenses...).
The color is AMAZING! really stunning and noticeable, even in environments with poor lighting.
Outside lighting (sorry for the messy makeup):
Overall, these lenses are perfect if you want a noticeable color, but don't expect enlargement. If you want enlargement, any of the X or W series of GEO Medical is perfect for you.
