Whether you like to wear discount glasses or the most expensive pair in the store, the frames are likely made out of one of a few different materials. Most glasses are made from plastic, metal or a composite material. Within each broad category you can generally find a handful of more detailed categories.

The type you choose will depend on your budget, the look you’re after and the comfort level of the material as the glasses sit on your face. Glasses are a highly individual accessory, and although technically a medical device, the glasses you choose still say a lot about you. It’s always a good idea to take your time when choosing eyeglasses, so you’ll find just the right pair for your face and your personality.

In the plastics category, cellulose acetate is probably the most common material. This type of plastic works for eyeglasses because it is relatively inexpensive and is available in a wide variety of colors, patterns and textures. The versatility of this type of glasses appeals to a wider range of people. Cellulose proprionate is another type of plastic used for glasses that is lightweight and good for making intricate designs. Kevlar is a kind of plastic that was developed for bulletproof vests, but also works well for eyeglasses that may be subject to force or impact. Many types of safety glasses or sports glasses are made from nylon because it is almost impossible to break. Nylon eyeglasses are usually only available in darker colors and may become brittle over time. Optyl is a type of plastic used for glasses that need to be hypoallergenic.

For metal frames, aluminum is one of the choices. Aluminum eyeglasses are lightweight and easy to wear, but are limited as far as different designs because it is difficult to weld. Cobalt is a more expensive metal frame that you won’t find on any discount glasses. Cobalt glasses are flexible, strong, lightweight and can usually be coated with a variety of different colors. Monel is a popular metal used for glasses because it can be made into many different shapes and colors without losing strength. Stainless steel is a metal that’s used often for glasses, and is one of the most corrosion-resistant metals to use.

Composite eyeglasses are generally made from a combination of different materials. Carbon fiber graphite is one type of composite that’s used for glasses to create the endurance of metal eyeglass frames for women while being extremely lightweight. It is naturally black, but you can also get it in different colors for eyeglasses. Copolyamide is a nylon blend that works well for eyeglasses, and Flexon 7 is a composite created from a titanium-based alloy that makes it quite durable. Titanium Ti-227 is a composite that’s about half as heavy as most metal eyeglass frames. This composite is also hypoallergenic, non-corrosive and stronger than regular steel. It is also difficult to extract and refine, meaning you won’t see glasses made from it in any discount glasses stores anytime soon.

Whether you’re wearing a pair of discount glasses from the clearance bin or a pair of high-end glasses that just came on the market, it all started with an eye exam. You may have had your eye exam as a matter of routine medical check up at your insurance company’s request, or because you haven’t been seeing things as clearly as you used to. Regardless of the reason, the eye exam is necessary to determine the nature of your vision problem and what type of corrective lenses you’re going to need. Eye exams may vary slightly depending on the doctor or reasons for having one, but most will contain a handful of basic elements.

Your eye doctor will usually want to hear all about the relevant medical history relating to your overall health and specifically your eye health. Do you wear glasses? Have you worn glasses? Have you had any eye diseases? Do any members of your family have eye diseases? He’ll want to see your current eyeglasses and ask if you’ve suffered any eye injuries that may have affected your sight. Once all of the questions have been asked and answered, you’ll probably move on to the eye chart. Most people have used the eye chart before, and it is used to help the eye doctor determine how clear your vision really is. It’s best to be completely honest during the eye chart, and not to guess at letters just to try and get as many right answers as you can.

An ocular motility exam will help the doctor to determine how well your eyes function when it comes to movement, tracking and reflexes. This test helps the eye doctor tell if you have any underlying problems with motility that need to be looked into more closely. At some point, a series of different lenses will be placed in front of your eyes to determine the degree of refractive error in your eyes, and what strength of prescription you’ll need in your glasses. Sometimes eyeglasses aren’t needed at all, but all of the vision tests will help him decide if you need some extra help.

Some of the other elements of eye exams include a slit lamp examination where a high intensity light is shone into the eyes and an opthalmoscopy to give the doctor a close up view of the retina, macula and other structures. Once the exam is completed, the doctor will give you his opinion on the condition of your vision and refer you to another doctor, if necessary. He’ll also write you out a prescription for your eyeglasses or contact lenses if you need any, and let you know when he wants to see you again.

If you revealed a family history of glaucoma or other eye disease, you may be scheduled for some additional tests to measure your field vision and intraocular pressure. The eye exam and subsequent tests should provide a thorough understanding of everything that’s happening with your vision and the cheap eyeglasses that you need to see clearly.

Once you’ve been diagnosed with a vision problem and have been prescribed corrective lenses, you must decide what you want to wear on your eyes to correct the problem. Glasses are often their first thought, but many people end up turning to contact lenses instead, or switching between the two. At first, the thought of inserting a contact lens directly onto your eyeball may seem a little creepy, but once that initial fear is overcome many people actually prefer contacts for several different reasons. The reasons to wear contact lenses may vary from person to person, but the main reasons are usually similar.

Wearing contact lenses enables people who need corrective lenses to feel as though they don’t need anything at all. Contacts allow for a natural look with no restrictions from glasses frames and so everyone can see their eyes clearly. For some people, wearing contacts allows everyone else to see them as they were meant to be seen. Some of the physical aspects of wearing glasses are another reason that some people choose to wear contacts. Glasses can squeeze the sides of your head or your nose, and have a tendency to fog up when it’s humid or collect raindrops when it’s raining. With contacts, you also don’t have to worry about frames impeding your vision in any way. Not only is the look more natural, but also your vision is also more natural. The frames don’t disturb your peripheral vision, and you won’t have to look through any portion of the frame during your day-to-day activities.

While better overall vision is the main reason to wear contact lenses, there are certain lifestyle elements that make many people lean that way in the first place. Wearing sunglasses is much easier while wearing contact lenses because you can just slide on a regular pair right over the contacts. It’s also easier and more convenient to play sports while wearing contacts, and you can even change the color of your eyes, if you so desire. The fashion elements of wearing glasses will also cease to be an issue when you wear contact lenses. Some people like to have a pair of glasses for every type of occasion, and with contacts this isn’t necessary.

Obviously, wearing contact lenses requires a bit of everyday maintenance and the risk of eye infection is greater if you don’t take care of them properly, but that is up to you. You’re not likely to run into any problems if you follow the care instructions for your contacts. If you like the reasons to wear contacts but are still on the fence, all you can really do is give them a try and see if you think they’ll fit into your lifestyle.

Soft contact lenses are generally more comfortable than rigid or hard contacts, but the hard contacts are usually a little easier to care for. You can usually find deals for cheap contacts that still work the same as the pricier ones. Of course, not all cheap contacts will give the same quality, so be wary when you’re looking. Just ask your eye doctor to go over the possibilities with you and he will offer recommendations if you decide to try them out.

One thing about wearing glasses that is much easier than wearing contacts is the fitting process. Since the contact lens sits directly on your cornea, it’s very important that the correct measurements are taken and that it fits properly. If the fit of contacts is even a little off, you may experience problems while you wear them. Clear vision and comfort are the two most important elements of wearing contact lenses, and both are affected by the fit of the lenses in your eyes. Whether you seek out cheap contacts or the most expensive ones in the store, the correct fit is crucial. All contact lens fitting consist of a few basic elements.

Before the fitting for contacts even begins your eye doctor will test your eyes to determine the strength of corrective lens you need. Then, they will help you decide on the right type of contact lenses for you. They will ask you several lifestyle questions and your preferences regarding the wearing and hygiene schedules. After the testing is done and decision about which type of contacts to wear is complete, you’ll need corneal measurements taken. Contact lenses are not a one-size-fits all kind of product, and the size and curvature of the lens must be correct. The doctor will likely use a device called a keratometer to measure your cornea during the fitting. This takes pictures of your eye to determine the curvature and size of contacts you’ll need for a proper fit.

The doctor will also measure the size of your pupils to help ensure properly fitting contact lenses. The diameter of your iris is also recorded and in some cases a tear film evaluation is taken. This helps to determine if you have dry eyes, and the result may cause you to rethink the choice for contacts. If you have a problem with dry eyes, wearing contact lenses can be quite uncomfortable as the day rolls along. At the least, you will be given eye drops and instructions on how to keep your eyes and contacts moist.

Your eye doctor may also use a biomicroscope to get a highly magnified view of your cornea, so they can watch how a trial contact lens fits in your eye. If the doctor chooses to go with trial contacts, you’ll probably have to wear them for at least 15 minutes to get a true sense of how they fit. They can then give your eyes a detailed examination and determine if the contact lenses fit properly or not. It’s common for contact lens fittings to take at least two office visits, to ensure the right size and style has been selected. Once the fit is good, you’ll get your prescription and you can go get it filled. Cheap contacts are usually available through specials or promotions at many optical stores.

Even though it may be more important when wearing contact lenses, fit is still an important factor when you are wearing eyeglasses. It is true that the lens of a contact sits directly on your cornea, but an ill-fitting pair of glasses can still cause you problems. Most of the issues that result from glasses not fitting properly have to do with pain. You’ll feel pressure in your head, on the bridge of your nose and in your eyes if glasses are too small.

If your eyeglasses are too big, you may have trouble keeping them on your face and you’ll spend more time trying to see with no prescription because the lenses aren’t where they’re supposed to be. The optician at the glasses place will likely take some time to ensure you have a proper fit, but there are also a few ways you can know if your eyeglasses fit properly.

The easiest way to know if your glasses don’t fit right is if they are too big and they slide down your nose as soon as you put them on. If you don’t notice any glaring signs like that, it make take a little more investigation to find out if they fit properly or not. When the glasses are sitting on your face, each eye should be looking through the center of each lens. If that isn’t happening, you could use an adjustment. You might notice that your peripheral vision is affected or there is a glare on the things you’re looking at, which indicates the eyeglasses are either too big or too small. If your eyes seem to be in the right spot, leave the glasses on for a few minutes, then take them off and take a look at your nose. If you see any red marks or indentations where the glasses were sitting on your nose, they aren’t fitting your face properly.

Most of figuring out whether the glasses fit properly is through feel. Pay attention to how they feel on your temples, on your nose and around your ears. If you can feel any pressure or pain in your head, you’ll need an adjustment. When you’re there with the optician, she can make minor adjustments after each check to slowly get just the right fit. The optician will also help you choose a set of frames that match your overall face shape. Picking out a pair of eyeglasses designed for a square face when you have a round face is a sure way to find glasses that don’t fit right.

It can definitely take some tinkering, but once you have a pair of new glasses that fit your face perfectly, you’ll be more likely to wear them more often. Keep an open mind when searching for new glasses, because what you envision and what fits are sometimes two different things. Choose comfort over fashion if it comes to that, because your eyeglasses won’t do you any good if your days are filled with headaches and other problems.
