Why do we wear glasses?

i need to wear glasses because i have a condition called NYSTAGMUS  and the muscles in the back of my eyes arent strong enough to pull items together. \n\n\ntry this take a thin piece of card about 5cms across by 20cm long and in the middle draw a line from top to bottom. every 1cm put a dot on it.\nthen hold it to the tip of your nose,tilt it down a little. when you first start,look at the furthest dot you drew, you should see two dots where your eyes havent focused yet. now make the end dots join, so there is one and then the next one up, then the next and so on.you SHOULD be able to rech the last one with strong eye muscles.\n\ni can only reach the second one. so my eyes need glasses that will make my eyes work harder, like in the gym, the muscles need to be worked out.\n\nthat is why i have to wear glasses hope it helps you.

I don't like to wear mine, either. However, since I use my computer as much as I do, and I also worked at Verizon, where I was on a computer for 8+ hours a day, my vision has gotten worse. There are many different styles of glasses you can get. Some have barely any frames, and they aren't as noticeable as the ones with full frames. I have a pair of them, and I like them much better. I can't wear my contacts, either, because I have allergies. My eyes get really irritated when I wear them. It does take time to get used to wearing them, but I think you will find that you can get frames that will compliment your face. Good Luck!

Optician means one who prescribe glasses to correct the refractive errors of the eye.  It is a Technical Course.

you should probably have glasses for when your contacts are not available, or when you go to sleep.  So in that instance, I would have regular glasses for that.

that depends on you do you want to get rid of your glasses or do you feel comfortable with them  do you want to travel or do you want to stay at home. i wear glasses and I would have to say travel  there is no way i would pass up the opportunity to get out fo the u.s for a vacation.

You know you need glasses when you start seeing things in a blur. Or you start getting heachaches if you read to much.\n\nOnly the optican can give you a diffinite answer though

Well fist off what the lens(glasses) does it help direct the light rays, so they can fall on the retina.\n\nIn "nearsightedness", the rays fall short of the retina (back of the eye where theres cones and rods-that helf see lights and colors). So nearshighted people need glasss that will help to make the rays so "CONCAVE" lens are used these help direct the rays to directly to the retina, these lens .\nNearshighted people either have eye balls that are to long or there eye ball lens is to fat (convex), so they only see near objects clearly. the light rays are nneded to be spread out befor they reach the eye the glasse dos this.\n\n\nFarsightedness- persons only see far objects clarely but not nar objects, this is because there eye ball is to short of there eyeball lens are to thin(concave)  (use diagram lins bellow)\nSo the ray incoming are needed to fucos on the retina, So CONVEX lenses bring these rays toger so thay can fall on the retina

Good question.  It all has to do with changing corneal dimensions.  At some point the whole system reverses and as your cornea and lens stiffen as you age you have trouble seeing things close (farsightedness).  Thank god for glasses or we would all be crashing into each other on the highway!

Because we are stimulated by our vision so its natural.

Contact lenses are great for a short term solution. I've worn glasses for half of my life. I went from glasses to contacts, but now, I'm back to glasses. The contacts just irriate my eyes now. For a permanent solution, I say go with the laser. Its costly, but well worth it in the end.

When you can't see clearly anymore even with glasses.

The lens in your eye may be too strong and thus focus the image of the outside world in front of your retina, or it may be to weak and focus the image behind the retina.  By placing a lens (glasses) in front of the eye, we can compensate for this by ensuring the image falls exactly on the retina, which allows for good vision.

No, I just makes you able to see.  I think people look more intelligent with glasses.

glasses.  You can always take them off for making out and other stuff.  Braces, although temporary, still suck.
