ESS receives numerous emails and letters every week from customers happy with their ESS products, often thanking ESS for saving their eyesight and even their lives.  Below is a sampling of the feedback that we receive from the field.

I got a pair of the photochromic safety glasses from ESS was excited to use them at a recent vehicle extrication class I taught. Being photochromic, I was unsure how well they would adapt to changing lighting conditions. These glasses far exceeded my expectations - both with light sensitivity (light to dark & dark to light) and comfort.

Having to wear them for eight hours a day, for multiple days, I noticed they were just as comfortable as any sunglasses I have ever owned.Emergency Service Responders truly appreciate the quality and safety oriented products your company produces.

As a Rifle Platoon Sergeant in Southern Afghanistan, I harped on wearing all Personal Protective Equipment (PPE) while on patrol. My entire platoon was equipped with one of your latest products: the ESS Crossbow. I had no idea this emphasis on PPE would save my vision, and the vision of several of my Soldiers. On 07 July 2012, while conducting dismounted offensive operations my platoon took several casualties as a result of an IED blast. My Weapons Squad Leader received shrapnel wounds to his face, in all areas except those protected by his ESS glasses. Undoubtedly his vision was saved by your clearly superior product. Additionally, on 07 October 2012 I was walking in the lead of our formation, clearing our route to our objective. While kneeling and interrogating a possible IED location, the IED was triggered, and sent the majority of the blast towards my torso and head. Despite the relative proximity to the blast I only received minor facial wounds. I owe my eyesight to your product, as the ESS Crossbows I wore took the majority of sand, shrapnel, and debris. Thank you for protecting my platoon and I, and all other warfighters serving our country.

I was in training at a demo range and went down range to proof a shot. Something had not gone to plan and when I got down range a secondary det occurred right in front of me. That det was about 2.5 pounds of C4. It was five to ten feet in front of me when it went off. When the blast wave hit me it threw rocks and debris straight at me. I was wearing ESS CDI eye pro and I didn't get anything in my eyes. The blast blew out one of my ear drums but thank God, and ESS, my eyes were alright.

There were a few chips in the lenses of my CDI's but they held up to the blast outstandingly. You and your team at ESS have made a life-long supporter of your eye pro. You brand is my choice for life. Thank you for your attention to detail while making your world famous eye pro. I wore your eye pro all through my tour in Afghanistan but never was as close to a blast as this one out in the open. You all are the reason I can still see my granddaughter's beautiful face, thank you.

Keep up the GREAT work, the defenders of freedom depend on you and the ESS team.

On October 24th, we were called to a building fire in an old wooden train garage. The fire started below the floor, which was made of large heavy timbers approximately 6" thick. To get to the fire we had to cut the floor apart. My LT and I each had a chainsaw and were cutting the floor apart, when one of us struck a piece of metal in the floor. We were both peppered with metal fragments on our faces, but my ESS glasses took the brunt of the force. We both had numerous cuts around our eyes but nothing penetrated the glasses and reached my eyes. If it wasn't for the ESS glasses I was wearing I believe I would have had eye damage. Thank you!

Just wanted to give you and your product a thank you. I am a retired police Sgt. and a current law enforcement firearms instructor. The other day during a rifle class (AR platform) I inadvertently (stupid error on my part) walked up on the right side of a shooter while he was firing. I was pretty close trying to correct his trigger press and grip manipulation. In the process he fired the weapon and I got hit directly in the glasses with a fired 5.56 casing.

The glasses were your ESS Crossbows. I was within about 12 inches of the ejection port. The glasses only sustained a minor mark on them and you actually have to look really close to even see that. The glasses did everything that they were suppose to. Thanks again. Stay safe Dwight.

I would like to send you this letter stating how effective your Innerzone goggles have been to me. Last December, our department responded to a fully involved structural fire in which I was on the initial attack and search for two victims trapped inside. The heat was much more intense than other fires I have been in. Afterwards, upon inspecting my gear, I noticed that the goggles were in great shape after being unprotected on my helmet through this situation.

We were recently dispatched to an auto accident where we had to extricate a victim from one of the vehicles. Our pressurized hydraulic line to the tool ruptured, and I thank my ESS goggles for protecting my eyesight and allowing me to continue working, even though I was covered in hydraulic fluid. Once again, these goggles have proven to me that they are effective and durable. Our whole department now uses ESS Goggles! Thank you!

Dear ESS, I am a member of our regional USAR Task Force and have been using my ESS X-Tricator goggles for over a year. These are the best goggles I've ever used--durable, lightweight, and very comfortable. These goggles have held up superbly to the rigors of structural collapse, confined space, trench, and vehicle extrication situations. I have been using the same tear-off lens cover since I bought my goggles. Whenever the tear-off gets wet, muddy, or oily, I just clean and dry it with no loss of visibility.
