|
Pencil Case Size Reading Glasses with magnetic frame. Choose from Turquoise Blue or Pink Champagne frame, and choose the power you need. Frames are Unisex, both colors are subtle, and since they are so small, neither color is very pronounced.
Weight: 15 grams (glasses only) , with case 25 grams.
Ultra Small, Ultralight, Ultra Slim reading glasses. Hard Protective case with shirt pocket clip is included. Steel wall plate with double stick tape is also included.
Special inverted bridge may be turned upside down for close up overhead work such as plumbing, painting, electrical or applying makeup.
Push button easy slide case pops up your glasses ready for use.
The Pencil Size readers are great for restaurants, map reading, task work, anytime you need the extra magnification. The tiny case fits in your purse, pocket or anywhere you want to keep the glasses for a quick read with tired eyes
Magnetic frame sticks to many steel surfaces, including the steel plate included with this kit. Steel plate has double stick tape on the back so you can stick it to a wall, workbench or any convenient surface.
Note that the magnetic attraction is mild - we cannot guarantee it will stick to all painted or textured steel surfaces. In testing we got them to magnetically stick to our file cabinet, electrical breaker box, stainless steel refrigerator, a galvanized steel signpost, and of course the steel wall plate included with the product. They did not stick to a textured, painted minifridge, dirty car, or textured coated steel on the racks in our warehouse.
Click for an Eye Test chart to select the appropriate diopter setting. The focusing ability of the lens of the eye allows objects at different distances to come into clarity with little or no conscious effort on our part. However, this focusing ability definitely declines with age. The focusing power of the lens in measured in "diopters". To focus on close objects, the lens has to focus increasingly more. The diopter power of the lens is age dependent. It is not fully understood why the focusing ability of the eye declines with age. The following table shows how the power of the lens changes with age: A 10 yr. old has 14 diopters power A 20 year old has 10 diopters A 30 year old has 7 diopters A 40 year old has 4.5 diopters A 45 year old has 3.5 diopters A 50 year old has 2.5 diopters A 60 year old has 1 diopter To read at the normal distance of 16 inches or 30 cm., the lens in the eye has to focus about 3 diopters. But, the lens is more comfortable focusing with about 1/2 of its full ability for any duration of time. Thus, from the above table, a 40 year old, with only 4.5 diopters of power available, may begin to experience difficulty reading at 16 inches or 30 cm. for any extended amount of time. A 45 to 50 year old may not be able to focus at that distance at all. It is possible to hold reading material further away than 16 inches, but eventually people will experience the phenomenon of their arms not being long enough to read! Reading glasses offer extra power so that the lens in the eye does not have to excessively focus. If no distance glasses are needed: * A 40 to 44 year old needs a reading glasses power of about +1.25. * A 45 to 47 year old +1.75 reading glasses power. * A person older than 48 to 50 may need a +2.25 or more in reading glasses. The exact power preferred for reading glasses may vary based on what distance an individual prefers to hold the reading material. |
