The prescription my dr. gave me is a -.75 rx for distance. How often and when should these glasses be worn?

That's approximately a visual acuity(VA) of 20/30...just slightly below the required VA to legally drive in most states. So, yes, wear them when driving for sure for your sake and others.

What eye color wear more eye glasses blue or brown?
no need to be rude....more specifically the question is do blue eyes or brown eyes tend to require eye glasses more often.
Why are glasses called glasses when they are really made of plastic?
Technically, if they are made of plastic, then they aren't glasses. They might be fake glasses, for diguises etc... Often, real glasses do have a thin layer of plastic over the glass so that they don't crack, but plastic doesn't do anything as far as focusing a person's eyesight.
Do you have to wear glasses all the time because you are farsighted?
No. It makes no difference how little or how often you wear your eye glasses. Wearing them all the time will not improve your unassisted eyesight, and not wearing them at all will not deteriorate your eyesight. You should wear them when you need them (for instance, driving a car, or maybe certain work or school related activities). This should be your choice.
How do you measure eyeglasses?
Measuring eyeglases can get a bit complicated so I'll just put down the basics!The precription in the lenses can be measured with a focimeter (It looks a bit like a microscope). Prescriptions are most often broken down into four parts:Sphere - Determines whether you are short of long sighted. (Measured in diopteres)Cylinder - Dermines Astigmatism (Measured in diopteres)Axis - The degree at which the cylinder in the lens sits to correctr astigmtism. (Measured in degress)Prism - Not a very common feature of a prescription. It alignes eyes that are not looking parralel to each other. It has a base direction to determine the exact way in which it is cut into or added to a lens. (Measured in diopteres)Reading Addition - A positive (+) addition to a prescription for enlargement. It is a Sphere only addition to a precription. (Measured in diopteres)Eye and Bridge Sizes - The eye and bridge sizes are of a frame measured in mm and are usually printed on the frame itself. The eye size is the largest measurement across the lens and the bridge size is the measurement accross the nose.Arm Length - The arm length is the distance from the temple to end of the arm on the frame. This is measured im mm.Pantascopic Tilt - The pantascopic tilt is measured in degress and is the angle at which the lens sits relative to the arm of the frame. Usually this should be between 10 and 12 degrees but this is variable.Vertex distance - Measured in mm the vertex distance is the distance between the back of the lens and the eye. This should usually be between 10 and 12 mm. Again there are variabes here.Fitting heights - Mainly used for bifocal, tirfocal, varifocal and aspheric lenses, the fitting height is measured in mm and defines the distance between the optical centre of the lens and the botton of the lens.These are the very basic glasses measurements and all should vary with prescription and by person. Please leave a message on my board if you need further information.She
What is the meaning of being near sighted?
Being near sighted means one is unable to see distant objects clearly. Nearsighted people often wear glasses or contact lenses to correct their vision.
How often do I need to replace my eye glasses?
A prescription is only accepted by the optometrist for a year. However if your glasses still work for you then you probably don't need glasses. If you're having trouble seeing then you should schedule an appointment.
How often do I need to get a new prescription for my eyeglasses?
If you go to the optometrist to get new glasses they will not accept a prescription that is more than 9 months or a year old. In that time your eyesight has probably changed. However if your glasses still do their job properly you don't really need a new exam.
Are there glasses made for seeing computers?
There are glasses prescribed specifically for people who work on computers. The need manifests itself because the "reading" section on glasses is often too close for the computer, and the "distance" section often too far. I wear glasses with a third section between the "reading" and "distance" sections, and I call this the "computer monitor" section. I have heard this type of glasses being called "trifocals."
What does it mean if someone peers over their glasses at you?
It usually means they can see you better that way. Glasses are often made with a prescription that works better for close-up things such as reading, but doesn't work as well for things that are farther away.

How to Get Affordable Reading Glasses?
It is very frustrating not being able to properly read the small text on your medicines, newspapers, ingredients, nutrition labels, etc., no matter how hard you squint. Actually, as people get older, the vision becomes weaker, making it harder to read small text. Paying for prescription glasses can be a little expensive. Aside from that, some people have various problems with their prescription glasses, while some are just not comfortable wearing those glasses. For those people who just need glasses so that they can read small text, there are methods on how to get affordable reading glasses. • Have your eyes checked by a doctor. The ophthalmologist is the eye specialist who would give you a prescription for your eyeglasses. If you had a recent eye exam, you can also use the prescription that was given to you so that you won’t need to go to your doctor again. • Go to a local eyeglasses store. Once you already have your prescription, you can try looking for reading glasses that match your prescription. Be sure to take note of the manufacturer and the style number. • Go to discount shops. Reading glasses in discount shops are much cheaper than those in eyeglasses stores. Since you have the list of the reading glasses that matched your prescription, you can try looking for that at discount shops. • Visit internet shops. Aside from discount shops, you can also look for online shops that sell reading glasses for less. If you found an exact match of the reading glasses that you need, you can purchase them through the internet shop; however, you’d be able to save more if you can find a discount coupon for that shop as well. If you are not using your reading glasses that often, keep them in a safe place. Have a case for your glasses to ensure that they won’t be broken. If you have old reading glasses and your prescription has changed, you can just have the lenses changed. This is much cheaper than buying new reading glasses.

Can you also buy glasses at an eye center?
Yes, most eye centers will have glasses that you can purchase. You will have to have an eye exam to obtain your most current prescription. Generally, yes. Most optomotrists either have their own eyewear store, or partner with a retailer, as in the case of Eyemaster. Another option you can consider is to shop online. Get your prescription locally, then look around for frames you like. You can often find the frames online for a lot less than you'll find in store.
