How do you know if your contact lens is inside out?
Look at the Lens
Before placing the lens in your eye, hold it on the tip of your index finger and look at it carefully from the side. Is it shaped like the letter "U" or it is flared on the sides, like a soup bowl? The correct shape of a soft contact lens should be like the letter "U". If its shaped like a soup bowl, then its inside out. Some people also recommend the "taco test" whereby you gently squeeze the lens so that the edges touch. If they touch completely, then the lens is right side out. If the edges flare out and dont touch fully, then its inside out. Simply flip the lens around and it will be positioned correctly for wearing.
Another way to determine if your contact lens is right side out is to look at it from the top. This is especially important if you are wearing the colored enhanced type. The edge of a tinted lens will be look very blue. If it looks greenish, then it is inverted and you should carefully flip the lens around in order to wear it properly.
Find the Engraving
Some contact lenses have factory engraving on them, done by special lasers. This can include the manufacturer information, model number, brand name or grade of materials used. While this is not detected by the human eye when wearing, it can be of help when trying to determine if you are wearing your contact lenses correctly. Some brands have a "1-2-3" engraved on them, so you would make sure this is the side facing downwards on your finger as you place the contact into your eye. If you can read this label, then the lens is inside out. You can remove it safely without damaging your eyes and flip it around for replacement.

Are contacts better than glasses?
Both are basically the same. It dePends on what you like.
Glasses- get in the way more and are not useful for sports. Easy to put on.
Contacts- help for sports, irritating to put in, sometimes hurt during the day but you can get used to them, are cheaper, make you look better.
Personally, I enjoy contacts more. I had both, but contacts were way better. It takes about a month to get used to taking them in and out, but it is worth it.

Can a corrective lens be in form of a contact lens?
Since contact lenses are corrective lenses for contact with the eye, I presume you mean the general case with optics.
The answer is that lenses can be in contact with each other and often are. But it is very difficult to put two lenses into contact without a gap, so these lenses are usually bonded together with optical cements.
Lenses have been made with liquid elements between lenses, too.
What is your vision if your contacts are 700 diopiters?
WOW! That's a big number. I'm guessing that it's probably -.700 or -7.00 at worst. If it's -700 I'd guess you are blind. Any negative number on your correction indicates that you are near-sighted. If the number is -.700 (or -.7) it means that you are less than one diopter nearsighted. One diopter is the strength of a lens that focuses an image at 1 meter. The negative of that (-1 diopter) is just the compliment of that lens.
What is the procedure to remove the taillight lenses on a 2002 Jeep Liberty?
It's easy! On the left, simply open the tailgate half way and look through the hinge area. You'll see two screw with a star hex head. Borrow a special "screwdriver" from the auto parts store, remove the screws and pull. You'll have to use a little force because the lens is still held in by a couple of snap fittings, but it will pop out pretty easily. By the way, no need to remove the connector plug for the wiring. The bulbs are located on each of those grey plastic caps. (Oh yeah, put a rag on your bumper below the lens to help prevent scratching)
