Well, it used to be that way(Soft/hard) for alot of years until the introduction of Camber lenses.
To simply put it, camber lenses works on the front surface curvature to negate distortion from the progressive design on the back. Resulting on a pair of progressive lens with minimal distortion.

*note* The "big boys" are not using this technology yet
I believe this is something new even to me!
''big boys'' May/may not need to come out with something like this as their progressives/digital/anti-fatigue are serving the population well
though they might in future.
I will end my piece over here by reiterating my point to all the forumners here.
There are many lenses in the market, claiming to be better/best of all at different cost. But do your due research or if not ask your optometrist/optician that you trust, to recommend you a lens that fits your need and not something which is too overkill.
Sometimes there will be BOMbastic terms are thrown at you so as to impress you and we will be like... Errrr ok la since sounds so good then take and easily causing you splurge on more than you need. Do take note of such instances and always reject if you feel that it(the lens) is too overkill. A trusted Practitioner will always recommend you what is needed and not what is better for their sales pocket.
Also there will always be a certain magician performing some tricks, to show you some gimmicky tool but in the end, all road(or in this case all lens) leads to Rome. It does the job but again, does it fulfill your needs in your workplace/job.
After these few days, i hope to let you guys know, i am just a worker not a boss. Here to prevent others from getting chop carrot. Don't have to visit my workplace but i can always recommend you places that are closer to your area of convenience. I have absolutely no commission promoting or talking about any brands too.
Cheers and thanks Eyezone for sharing.
