Removing Anti-Reflective Coating from glass lenses


 Removing Anti-Reflective Coating


Anti- reflective coatings sometimes will start to flake off your plastic lenses if you have the older type of coating.
As I type this, I'm looking through lens that are now clear as new. My progressive glasses are 3 years old and are polycarbonate, scratch resistant, UV protected with a $65  anti-reflective coating.
About an hour ago I could hardly use them and pricing new lenses were $400. When I asked the Optician about the quick deterioration of the coating ( they now offer a new and improved coating costing $135) he asked if I sweat a lot, as that can cause problems. Lately this has been true, because I have been doing spring yard work and digging a garden pond causing the lenses to deteriorate fast.

This is how I removed the coating from my lens.
  1.  I took standard iodized table salt (figuring if salty sweat was effective, a salt solution might be also), poured it into a bowl of water, heated in microwave to a temp I could touch, making a dissolved salt solution.
  2. I took bounty pick-a-size paper towels and began rubbing with the solution, keeping it nice and wet.
  3. I intermittently washed them off with dish-washing soap to check my progress and it only took about 45 minutes. The rubbing and solution didn't scratch my lenses, but did remove the film coating. Not a bad return on my time!  
  
  4. The photos show the difference in the removed and remaining  coating. When I did the process of removal, I didn't take my frames off. I have zoomed to the hinge and nose and you can see where I was not able to rub the solution very well and the coating remains.





So, if your lenses have progressed to the point where you will need new ones, give this a try. You have nothing to lose, since you can't see anyway!

Camping at Torreya State Park

Torreya State Park is located about 60 miles west of Tallahassee, Florida in the “Big Bend”. This park is noted for its varied terrain, ranging from hardwood to swamp wetlands and an area we Floridians could call “canyons” (large washed out clay hills). It’s the closest thing we can find around here that is similar to the beautiful Appalachian Mountains. The park has a nice network of trails to explore. My 13 year old son and I arrived at the park on Friday afternoon at 3:00 pm, the first day of spring. We had made reservations ahead to ensure our sites in the primitive camp areas. Because our region had been receiving abundant amounts of rainfall, we knew the mosquitoes would be in full force. We were not disappointed. We came prepared with plenty of bug repellent.  This trip could be called an "Introduction to Backpacking" for me and my son. We have done car camping, but yearned for a taste of “true” camping.

Review of Crocs Men's Modi Flip Flops

Review of Crocs Men's Modi Flip Flops As a result of an injury and suffering from Plantar Fasciitis and a heel spur, I needed some comfortable flip flops that offered support and heel comfort.  I previously had some Croc knock-off, slip on shoes and they felt comfortable, so I did some online research, reading reviews about various Croc shoes, and determined that the Croc Modi Flip was highly regarded. I went to my local sports store and tried on half a dozen flip flops to see which were the most comfortable, comparing them to the Modi Flip, and determined I like the Modi the best as they seemed to provide the best comfort for my heel. As an added bonus they have nice foot massage bumps. I first bought size 11 thinking it fit the best, but once at home, sitting and walking in the house, I decided they were a little snug across the top of my foot, so I exchanged them for size 12. They fit perfect, not too tight when sitting in a chair, yet snug enough when walking.
