The mysterious eyeglass prescription explained A low powered lens may contain 0.75 diopters and a strong one 5.25 diopters. An eyeglass lens is designated as either a “plus” (+) power or “minus” (-) power, depending on whether we want to decrease or increase the focal length of the eye itself. [...]
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.

Following surgery to remove a cataract-afflicted lens and its replacement with an artificial one, several people manage to see clearly without the need for spectacles. It is, however, difficult to predict the exact characteristics of the lens required for a particular patient before the surgery. Some people continue to have some refractive error and require either spectacles or contact lenses for sharp vision. Changes in the position of the lens may also occur during wound healing, thereby...
How many pairs of spectacles and sunglasses do you own?I’ve just counted them and I have 21 prescription glasses, as well as some for reading and some multifocals.
