Greater Lens worth it?

[genr8k]

I am leveling up Naramon and sortie has only been giving me regular lenses. I have plenty of greater lenses for other focus schools, just not Naramon -_- 

Is A greater lens worth the Forma and argon crystal?  

Im not worried too much about the argon because it is easy to farm, but I can only build 1 forma a day, and almost all of the weapons that I need to craft need forma.

I tried to buy A Greater Lens, but found out that you can't trade them.

i already have regular lenses on the weapons and warframes I use the most.

Regular lenses are fine. Greater lenses are only a bit stronger then the regular ones. So if you dont have the resources to craft them its best to just not go for them.

For reference,

Normal lenses gain focus equal to 1.25% of affinity 
Greater lenses equal to 1.75%.

Sure the effect is very noticeable with a full gear setup. but its no major upgrade.

You only need 1 greater and yes it is worth it.
