As promised, the courier delivered my specs today, a quick review. The one with a 1.74 index lens. I gotta say, to Seannie, you were right about the 1.74, with my prescription, all I can notice was about a 1mm or so difference between the thickness of my past 1.67 lens and this new 1.74 lens.
The korean lens are surprisingly very well made. Initially I had thought of going with just getting a pair of nice frames, then bringing it to one of the local shops to have lens fitted for them. However, the price offered by the chinese retailers were too good to resist. I paid only about 80 SGD to have 1.74 index lens fitted into them.
More about the lens, they look just as clear and sharp as about all the other lens I had. Single aspherical, reflection coated, anti UV coated, anti scratch. Ordered and cut exact to my prescription that I provided. Been comparing with my other daily spectacles and apart from the slight lens-pupil distance difference, I dont notice any difference in visual clarity.
I got to speak to the chinese optometrist that made my spectacles, he did affirm that with my prescription, there is also gonna be minimal thickness difference between a 1.67 and a 1.74 lens. Lesson learnt, go for 1.67 from now on.
A picture of my newly made specs from China. Love it!
