Why I Bought My Prescription Glasses at Costco So off I went, without vision coverage to help pay for a frame and lenses, in search of new eyeglasses. Fortunately, my health insurance covered most of the cost of the eye exam, but that was it. The rest would come out of pocket. I wasn't necessarily [...]
Eclipse: What Happens If The World's Giant Solar Farms Go Offline? Experts have warned that looking directly at the sun during the eclipse, while wearing sunglasses. Observers could suffer temporary or permanent loss of eyesight unless they use special eyeglasses designed to withstand the sun's rays. By Zerohedge. [...]
As world's population ages, blindness rates likely to grow The researchers estimate that 0.75 percent of the world's population was blind in 1990, compared to 0.5 percent in 2015. Over the same period, the rate of moderate to severe vision loss fell from 3.8 percent to 2.9 percent. But those rates are The [...]
Refractive Changes Induced by Spherical Aberration in Laser Correction Procedures: An Adaptive Optics Study In 10 eyes (mean age: 35.8 years) under cyclopegic conditions, spherical aberration values from −0.75 to +0.75 µm in 0.25-µm steps were induced by an adaptive optics system. Astigmatism and spherical refraction were corrected, whereas the other natural [...]
Progressive spectacle lenses, also called progressive addition lenses (PAL), progressive power lenses, graduated prescription lenses, and varifocal or multifocal lenses, are corrective lenses used in eyeglasses to correct presbyopia and other disorders of accommodation. They are characterised by a gradient of increasing lens power, added to the wearer's correction for the other refractive errors. The gradient starts at the wearer's distance prescription, at the top of the lens and reaches a maximum addition power, or the full reading addition, at the bottom of the lens. The length of the progressive power gradient on the lens surface depends on the refractive index of the lens, with a final addition power between 0.75 to 3.50 dioptres for most wearers. The addition value prescribed...
The rear of the unit has several connections: BNC antenna, 12V input, DIN socket for a recorder, external speaker, RS232C for computer remote control, and On/Off switch for computer/manual control. Back in the day you could purchase ScanCat Gold software for about $95. 00 that would allow computer control of the unit. This unit was purchased to save space at my desk as it’s quite small and serves as my main source of longwave, medium wave, shortwave, and VHF/UHF reception. For HF it’s hooked to an S9 43 foot vertical antenna with many (50+) radials. S9 Antennas unfortunately is no longer in business, but when the company had just started up I purchased the 43 footer for ham use. S9 antennas was eventually sold and the antennas were available from LDG Electronics last time I looked.

Rectangular Metal Reading Eyeglasses (+ 0.75 Diopter Strength, Black) These glasses came exactly as described. The metal frame is sturdy without being too heavy, it's wide enough for a round face, and doesn't slide down my nose while I'm using them. I do not need reading glasses yet. But my eye doctor recommended the +.5 ... [...]
Washington Nationals starting pitcher Stephen Strasburg is just 28 years old, but it seems like he's been around forever. The 2017 season is his eighth in the majors, and although he's had a good (if not injury-prone) career, he may be in the midst of his best campaign yet.He may also be the difference-maker in a Nationals rotation that can match up with any other in baseball. Yes, even you, Cleveland Indians. With Max Scherzer likely to generate most of the National League Cy Young buzz and...
Nikon D850 and the new guitar problem by Christian HandlI had the chance to play with the new Nikon D850 very early (August 30th, 2017) and could also work with RAW files thanks to Raw Therapee. To make it short, the file quality is very good, nothing to complain about. On the other hand, also nothing to get too excited, as the files of my beaten D800 are more than good enough still for 99% of my work. Even the files of the D750 are perfect most of the time.Warning, this is pixel peeping...
