For the record: Spectacle Hut has stopped providing Nikon lenses. See here for authorised Nikon spectacle lens dealers in Singapore.
Nikon-Lenswear for Singaproe | Store Locator. The only reason that I think they have done that is because Spectacle hut has chosen to use a cheaper brand/lens manufacturer in order to earn more.
This is important for high astigmatism. So far, only Nikon lens has worked for me very well (1.6 index) in giving me the widest distortion free vision. Also very important, to not use 1.7 or higher index, and use index below 1.7 due to unavoidable color aberration at the peripheral vision which affects all lenses regardless of manufacturer. I found this the hard way after spending on 1.74 hi-index lenses. I found out that that while looking at my widescreen LCD/LED computer monitors which fills up almost 3/4 of my vision while I do work, the fonts have too much color shift looking through towards the edges of the lens causing double lettering in different colours.
One last thing is to check that your spectacle nose pad is made of silicone (you can test it - it is quite sticky even with somewhat oily fingers) and not PVC (you can test it - it slips very easily). If you nose pad is made of PVC (vinyl), the spectacle will tend to slip down your face. The sad thing is that Spectacle Hut gives me PVC nose pad, what a s**t. All spectacle shops are giving silicone nose pads, I don't know why Spectacle hut is giving pvc nose pads.
