If you are currently in the market for new pair of safety shooting glasses, I would recommend the ESS Suppressor.   It is the first spectacle frame design for use with over-the-ear hearing protection and comms gear.  The temple arms is ultra-thin and help keep noise out and eliminate hot spots by minimizing interference with the padded seal of ear cups.   The complete kits comes paired with elite crossbow lenses.  The suppressor comes in two great color options, the black and the terrain tan.  All the ESS Eye Pro exceed ANSI Z87.1-and MIL Spec. and OSHA safety standard.  The lenses are ballistic tested and shatter resistant, this is a great investment for one of your most important organs.  There are six additional lens options available.  ESS also created two Rx insert that can be used with the ESS Suppressor. The first is the U-RX insert, this universal Rx Carrier is the first to interchange across brands in a wide variety of ESS and Oakley Ballistic eye shields and goggles.  The kit includes two sets of nosepieces and goggle adapters for both ESS and Oakley products.  The U-RX is compatible with the Oakley Ballistic M-Frame 2.0/3.0 and Oakley SI

Eye-test

Okay, so I figured I’d go a little more research oriented this time because I was interested in the history behind the progressive lens, so bear with me if this post is a little drier but it will be informational. The progressive lens has always been a mystery to me, mainly because I think its technology is intriguing on how someone can magically put two magnification powers in a lens with no visual transition between prescriptions.

Here we go! The initial progressive lens was designed by Owen Aves in 1907, yes you heard that right, my mind was blown when I learned that the first progressive lens was designed in the early 1900’s! Sir Aves lenses were not designed specifically for the public use so the first modern commercial lens was not actually released until 1953 by Varilux & Carl Zeiss. Figures the big boys of the industry would be the ones to release to the public, but I guess it makes sense.

The issue with the initial released progressive lenses was that they were not asymmetrical, instead the reading point was about 14mm below and about 2mm from the nasal side. Therefore the patient would have to tilt their …

What do you picture when you hear the word Bifocal? I picture a lens with a thumbprint area on the bottom filled with magnification. If you pictured that too, you are correct. But, there are so many more kinds of bifocals out there…

Flat Top lens (also known as D-seg or Straight Top): The most common bifocal in our time is called a Flat Top 28. It has this name because the flat portion on the top of the magnification area is 28mm wide. The Flat Top 28 lens is good for many purposes. The ideal patient would use this lens to do everyday activities like read, drive, or for leisurely activities. For most people, this 28 millimeter area of reading magnification works perfectly. For patients that like a little bit bigger of reading magnification there is also a Flat Top 38, which of course is just like the 28 but has 10 millimeters more room across the lens.

Alternately to the Flat Top on might select a Round Seg bifocal lens which is basically a Flat Top bifocal turned upside down. This created a reading magnification bubble, so to speak, instead of the harsh line of a Flat Top …
