Here are some more information for Double Lens:

Prescription eyeglasses are glasses that have been prescribed by an optometrist to be worn by someone who has been diagnosed with a certain eye condition. Depending on the condition, a different lens will be prescribed.

Prescription eyeglasses are broken down into four different categories.

The Single Vision Lens has the same focal power from the top of the lens to the bottom of the lens. People who have been diagnosed as farsighted, nearsighted or with having astigmatism can wear single vision lenses to correct these types of eye disorders. Astigmatism is a condition that doesn't allow light to reflect on the retina, thus causing distorted images.

A Bifocal Lens is used to correct a condition call Presbyopia. This disorder usually occurs in people in their late 40's. If a person has been diagnosed with Presbyopia, they can't focus in on close objects. That is where the Bifocal Lens is helpful. The top of the lens is used for distant vision and the bottom of the lens is helpful with close vision. People with Presbyopia need both types of Focal View on their prescription eyeglasses.

The Trifocal Lens-meaning they have three focal views-is designed similar to the bifocal lens with the exception to the center focal point on the lens is for intermediate vision.

The fourth type of lens is the Multi Focal lens. It has more than one focal view; therefore a Bifocal and a Trifocal are types of multi focal lenses.

Other types of lenses that are specially designed for other purposes include the Computer Lens. They are designed so that when sitting at a computer, a person can view the monitor and papers nest to the monitor at the same time. And then there are Double Bifocals, which are rarely prescribed, but when they are it is usually for pilots, electricians or other professions that need to have close vision overhead.

LG Louvre GC990: Double the Features, Double the Fun

Mobile phones with high definition features or 12MP cameras aren’t really new but a device that sports both features in one package is certainly big news.  Korean mobile company LG is currently at the forefront of this innovation with its concept device, the LG Louvre GC990.  Whilst this phone is presently in the development stage (LG has not confirmed a release date, or if the device will be released at all), the mobile phone industry is already abuzz over the Louvre’s exciting features.

As mentioned, the Louvre GC990 will come with both a 12 megapixel camera as well as HD video recording.  The 12MP camera is equipped with the German-made Schneider-Kreuznach lens.  Schneider-Kreuznach is associated with digital cameras so this feature alone speaks of high quality.  Apart from excellent optics, the camera is also outfitted with enhanced digital zoom options, autofocus, smile detection, Xenon flash as well as tap to focus function.  The zero shutter lag feature makes sure you are able to take shots quickly – perfect for capturing spur-of-the-moment images.

HD video recording is at an extraordinary 30 fps at 720 pixel resolution.  The camera is able to play back Xvid and DivX video formats and the phone’s TV-Out element should make for more enjoyable film viewing.  There are also other multimedia alternatives as the Louvre can play file formats such as MPEG4, AVI, H.263/264, MP3, AAC, AAC+ and eAAC+ amongst others.  There is also a built-in FM radio.

Connectivity on the Louvre GC990 is fully supported with 3G, WiFi and Bluetooth.  You can also connect your device to a computer by way of USB 2.0.  Geo-tagging functions for both videos and photographs are also available on this phone so naturally, you get a GPS receiver as well as A-GPS support.  Another noteworthy feature is the Louvre’s user interface, the S-Class UI which allows mobile owners to manoeuvre the device through the help of a user-friendly 3D cube.  The Louvre is ISO 3200 compliant and is DLNA capable.

You will also find other standard features on the Louvre such as personal information management tools which include a calendar, to-do list, notes and world clock just to mention a few.  There is also a camera dedicated to video calling, a built-in accelerometer which is responsible for the phone’s auto-rotate function and handwriting recognition over the 3.2 inch touch display.

Should LG decide to offer this to consumers, improvements may have to be done on competitor devices such as the Omnia HD and the Satio to keep up with the Louvre.

Why do I see double vision whenever I wear contact lens?

I have gone through like 10 brands of contacts and many prescriptions. My eye doc says its becuase when I go inside, my pupils get way too big and the contact is too small and doesnt cover up the vision perfectly. What do you guys think? I have literally tried everything, even hard contacts. They are the right prescription because I can see good, just when I go inside everything goes double...

Your eye doctor seems to be right. Try increasing (significantly) the indoor lighting, and this effect will be reduced.
