Review:
The development of hydrophobic and oleophobic coatings on lenses has required changes in processing lenses. Blocking pads are obvious, and have been reviewed here.
One problem not addressed is the "disappearing dots" that many lensometer marking inks leave. How many times have you spotted up a hydrophobic lens, only to not be able to see the dots when you get to the layout blocker?
PSI addresses this problem with their True mark Hydro ink. This ink will leave a solid red dot where spotted and it will stay until it is wiped off. It works just as well with regular lenses. It does not separate on the ink pad, but be sure to shake the bottle before applying, as it does separate some in the bottle.
In short, it does what it's supposed to do, and does it well. If you have ink problems, you can solve them with this product.
Would you purchase this product again?
I will definitely purchase it again when I run out. The 2 oz bottle will last me a very long time though.
I have no financial interest in the company who makes and/or distributes the product I am reviewing or in any of their competitors.
