Hi Kristin,
We stock the full range of Pilla products, and the 60HCP has not been very popular in the UK.
The 46N was perhaps the most popular lens since the 65Max Orange came out a few years back...but Pi£$a soon changed it to the 44N...a simple change of 2% in the light transmission, which is extremely small.
I personally like Purple lenses as they make my eyes feel relaxed and give me some enhancement on orange targets although i find the 66N too pale for my eyes.
I regularly hear that people should use the palest lens possible so as to let the most light into the eye. This can be useful, particularly in poorer conditions, and also ensures the pupil is constricted therefore giving slightly sharper vision, however the amount of extra clarity that is actually useful that comes from a miotic pupil in good light, is realistically next to nothing for MOST people.
We also need to look at how light sensitive someone is: i often wear very dark lenses as i find i struggle in slightly brighter than normal conditions - for playing rugby I've got some tinted contact lenses which are amazing, as catching high balls into the sun was a nightmare.
Others may find a dark lens dulls things down too much and they lose the detail. Lens colour is very specific to the individual too - tints simply allow some wavelengths of light through and block others, different wavelengths have different "energy values" and some people find their visual cortex (the brain's processor) operates poorly in some colours and optimally in others.
Reds and browns tend to overwhelm me a bit so i often go for blues, grays and purples. Other folk tend to love the bright contrast a red or yellow lens gives them - as we get older the lenses in our eyes change too so we can sometimes find tints that we liked in the past become less effective...
