Optical and non-optical vision aids for reading
People with low vision may feel frustrated to read books, newspapers and other materials. These effortless enjoyments impose much more requirements on visual impaired individuals. Some patients simply give up reading.
In fact, there are still many types of low vision aids for reading. Some of them require a prescription from ECPs and others are nonprescription ones. Patients should always get advice from their doctors in devices choosing.
The simplest and most affordable device is handheld magnifier. Variations of handheld magnifiers include that contains reading lamps, the type that is mounted on height-adjustable stands or hand around the neck.
Strong reading glasses and bifocal eyeglasses with high-power reading segments can also be your choice. Reading telescopes can be handheld or mounted onto special eyeglass frames with enhanced nose pads and padded bridges.
Video magnifiers are another more advantageous option, although they cost much more. These devices project printed materials on a closed circuit television (CCTV), monitor or computer screen. The patient can see those materials on the screen, just like watching TV. All common parameters such as magnification degree, brightness, contrast and color are under adjustable. In addition, the gesture of the patient can be more natural.
You can also get portable reading from a special device system. The device rests on your reading materials and magnifies it. And you can read materials on your eyeglasses projected by the device. You hold the device and can move it in any direction to magnify certain parts of a page. The device can also magnify curved surfaces such as cans and pill bottles.
In addition to the above low vision devices, inexpensive non-optical adaptive aids are also helpful. People with low vision may have difficulty recognizing certain objects. Large-print cookbooks, large-numbered playing cards, clocks, telephones and watches are easier for reading. Other “devices” include large felt-tip pens, wide-lined paper, color-coded pill boxes, voice-recording electronic organizers, signature guides etc…
Regardless of any type of vision aids you choose, good lighting is critical. People with impaired vision need a larger amount of ambient light. Natural sunlight is the best for reading, so that low vision patients can sit near a window during daytime reading. If natural lighting is beyond your hand, use “full-spectrum” incandescent bulbs, rather than harsh fluorescent lighting. While the former type is closer to natural sunlight, the latter type causes glare and discomfort. You should choose bright light bulbs or lamps with three-way sockets.

i have a 5 watt-6 channel realistic trc-208 (i know its old), its in pretty good condition and can receive and intercept cb radio frequencies (obviously).....so i want to know how much range i can get out of it.......i use the best energizer aa batteries, I use the stock antenna (telescoping top loading antenna....about 2 feet long) and i live in a heavily wooded area......i plan on mostly using this outside....and want at least to have one mile of range when i am communicating to another handheld radio......any ideas on how far my mileage can be?
Just ask your buddy to test the range with you.
