A bit off topic, but cool nonetheless. In Discover Magazine’s current issue the article Wave Energy: Can a mechanical snake that surfs the ocean squeeze enough watts from water? is something all renewable energy enthusiasts should read. I love reading about innovative technology that can decrease the dependency on fossil fuels. Wind energy is the type I’m most familiar with. (more…)
Up until a week ago, I couldn’t tell you what an RSS feed was and why it would benefit you as you browse the web. Well, I’m going to lay it all out for you so you can take advantage of it if a site you enjoy going to has this capability. First, RSS stands for many things depending on version, but essentially “Really Simple Syndication” in the current version (2.0). So why is it the neatest thing since sliced bread? It allows you stay connected to a site in a passive way. If you don’t visit a site everyday, but still want to know if someone wrote something worth looking at, RSS is for you. (more…)
Sorry about this change yet again. Why the change? There was an inherent problem with other theme although it looked great, it eventually would push the other sections down over time, every month to be exact. Since there isn’t anything underneath the archives section, it can grow without disturbing anything else. Well, what do you […]
I just joined the Contact Lens Society of America (CLSA). I recieved the standard welcome letter and 2 magazines. The magazines are called Eye Witness. It’s very good. It’s done every quarter so you only get 4 a year 🙁 . You also get a directory of doctors and contact lens fitters. As I said, the magazine is great! One of the articles (more…)
This new format is great. For those of you who want to know what I’m working on, I’m doing several projects. I tend to do projects in series as opposed to one at a time.
Things I’m doing include,
Not too long ago in the field of opticianry, iseikonic lenses were a common topic. I asked some seasoned opticians and an optometrist to find out why iseikonic lenses have decreased in popularity.
For those of you who don’t know, iseikonic lenses are lenses in which the magnification has been balanced. Each lens produces a certain amount of magnification or minification (small-ification if you will). Differing magnifications become a problem if there is a significant disparity between the two lenses. Orthodoxy holds that a difference of 5% magnification or more is enough to break fusion in most individuals. The difference in image size produced by the difference in magnification is called aniseikonia. Fusion is the process in which the two eyes combine their respective images into one. When fusion breaks, people complain of diplopia, or double vision. Some people who do not break fusion, but still have magnification differences of over 1%, may complain of headaches and nausea when wearing glasses that do not correct for the magnification difference. Some people with a high astigmatism that significantly supercedes any astigmatism in the other eye will also experience similar problems. People in this category have meridional aniseikonia.

Original Site I intend to keep the original site up in case some of you are perturbed by the change. Just click the link above, and it will take you to the original page. The idea of using a blog appeals to me personally and intend to be as objective as possible whenever I post […]
As you can see Opticiansfriend.com 2.0 has been published. I used a blog publishing program called WordPress 1.5.2 and a theme done by Beccary. I think it looks pretty good and feel that this type of software makes it easy to manage the content of the Opticiansfriend.com website. The forum is still here of course. […]
