A method for the early prediction of risk of hypertensive disorders in pregnant women, including for example eclampsia, mild pre-eclampsia, chronic hypertension, EPH gestosis, gestational hypertension, superimposed pre-eclampsia, HELLP syndrome, or nephropathy. As the forming mold, a forming mold having a curvature distribution on the forming surface is utilized. The two chromaticity groups are substantially equally away from a target chromaticity in directions reverse to each other. Advantageously, continuous transitional regions are formed relative to the reshaped portions to provide vision for intermediate distances. Methods of transferring heat include applying heat energy to a vapor barrier wall, flowing liquid through a liquid flow channel, pumping the liquid from the liquid flow channel through a primary wick, and evaporating at least some of the liquid at a vapor removal channel.
