Michelle: Can I Reduce Prescriptions to -7.00?
Michelle posts an update in the forum: I have been wearing the reduced prescription, -7.5 contacts in both eyes for 3 weeks now. I received my glasses, +1.5, last week and have been using them for computer use. I have noticed that if I can get outside every day my eyes both clear up pretty quickly in 10-15 minutes. Besides a dog, having 4 year old twins helps too :). It takes twice as long indoors in the mornings. Since starting the program 6 weeks [...]
Breast Feeding: Why It Matters to Baby Eyesight
This article, just a short intro to some infant eye development concepts. If you'd told me in my 20's that I'd one be talking in a quasi-expert capacity about infant eyesight, I'd have told you that you're crazy. Back then I was mostly just interested in offshore boats and vintage motorcycles, and ways to amusingly shorten my life expectancy. But here we are, a decade or two later. Old man Jake is going to tell you things about infant eyesight. Read the rest of this [...]
Headaches & Fatigue: Measure Your Pupillary Distance (PD)
PD (pupillary distance) can be an important part of your lens prescription, and notably affect your general well-being. If you have high myopia, and in particular high myopia and high astigmatism, an incorrect PD value can cause blurry vision, double vision images, headaches, nausea, and fatigue. In particular a small error in PD with a complex prescription might just give you a small headache sometimes, something that might be very vexing and difficult to pinpoint the cause of. I've had hundreds of students over the [...]
Never Change The Diopter Ratio
Roy posts in the forum: So I started my next reduction Right: -7.0 -> -6.5 Left: -7.5 -> -7.0 I just started yesterday and notice that my left eye gets the flash of clear vision more easily than my right eye. My snellen results are (if I check my vision in optimal light and pull focus for a good minute) Right: 20/30 Left: 20/25 Is that normal for one eye is pull focus faster? I felt like my right eye pulled focus much better previously [...]
The Guru vs. The Medicine Man
Twitter. Not sure what I just got us into, with the social bits. Yesterday I received a tweet thing, someone asking whether I have a medical degree. I respond with a link to Steve Leung's interview. I feel it addresses the question while adding necessary context. If I'd taken more time, I might have added this: I'm not "practicing medicine". In the sense that we understand the term, we refer to a very specific and regulated profession which deals with treating illness. I don't treat [...]
The Most Fascinating Thing
One of my favorite friends is a TV show producer. He used to be a high roller. These days you mostly find him complaining about how YouTube is taking his lunch money. You should hear him. The youth is all going to online media and nobody is buying TVs or traditional media subscriptions. He says that traditional media is completely freaking out, behind closed doors. The writing is on the wall. He's now trying to learn how to get his own thing going on YouTube, [...]
