People who complain of certain eye problems will usually see their primary care doctor or emergency room physician. These doctors can diagnose some of the diseases and probably treat some of them. However, much of the treatment is reliant on an eye doctor. If the patient needs glasses, they will have to go to an opthalmologist for the full examination. However, there are many reasons why a person would need an eye doctor, and these will be discussed.
If an eye doctor saw a patient, most likely there is something wrong related to their eyesight, or there is an issue in or around the area of the eye. Some medications are recommended to only be prescribed by an eye doctor. There are several questions the eye doctor might ask to get a better idea of what is wrong. Is the patient having trouble with vision? Does it hurt, and if it does, when does the pain occur. Does bright light affect the eye? Does the patient have a headache? Did the pain or vision loss come on suddenly, or has it been slowly occurring?
There are many reasons as to why someone would have vision loss, eye pain, or a headache coinciding this eye problems. A thorough examination needs to be done to diagnose the problem. Looking at the patient or inspecting them can give many clues before other evaluations are done. A traumatic injury would be obvious, but other evaluation would be needed to make sure there is no vision loss.
Other serious eye problems include diabetic retinopathy, glaucoma, detached retina, cataracts. Vision loss due to high blood pressure can be a serious emergency. However, they also treat many patients who are not emergent and need only new glasses.
Since this is a specialist, they are the ones who will perform surgical procedures when necessary. Eye conditions which might need surgery to explore the situation or for definitive treatment are cataracts, a detached retina, or certain types of glaucoma.
There are certain medications that an eye doctor would be more knowledgeable about prescribing. Some medications if given can cause severe complications to the eye, and the patient would need to see an ophthalmologist emergently. So, the usually are left to the ophthalmologist alone to prescribe.
Going to an eye doctor is usually reserved for people who have already seen their primary care doctor, and their issue with their eyes or vision may need a more experienced physician in that area. They deal with a variety of issues from prescribing eye glasses to treating severe eye cases that might need surgical treatment.
A person who may need glasses by themselves can go to an optometrist whose primary job is to examine people to provide them with a pair of eyeglasses. There are many commercial eyeglass shops that can be found with discounted prices on eyeglasses.
Back in the days of our grandparents the choices of eyeglasses frames were very limited. There was a basic style for men and women that all frame manufacturers followed. Luckily, there have been a lot of changes in the selection of frames we now have to choose from.
The eyeglasses frames of today offer a variety of styles and colors. You will likely have over a hundred different frames to choose from when you go to your local eye doctor's office. Frames are marketed by the most elite designers in the world and some celebrities have designed their own eyeglasses. There is no doubt that modern frames are nothing like those in our grandparent's day.
Deciding on a frame
There will be several factors that you need to take into consideration when picking out your eyeglasses frames. Choose carefully since you will be wearing these glasses daily or most every day. You do not want to pick a pair that does not flatter your face.
Face shape: When deciding on a frame one of the major things that you need to think about is your face shape. Your frames will need to be accommodating and flattering to the shape in order to look good. Diamond shaped faces will look better in a frameless pair of glasses, and square faces will be flattered by long slender frames. You will want to consult your optician when trying to decide.
Color and complexion: Just as with cosmetics you will have to know the correct color that goes along with your face. Some people are warmer toned like reds or orange, while others are cool like blue or lavender. Knowing your base color will help in choosing the right frames.
Size of frames: It is vital that you make sure your frames are the right size for your face. Picking eyeglasses that are too large or small will not look very flattering.
Material making up the frames: The material that makes your frames is also important. Some people have heavy lenses and will want to choose a titanium frame which is a lot lighter in weight. Nylon or even flexon is a great frame to choose when buying eyeglasses for children. The Nylon is especially hard to break, and the flexon is bendable. If you are allergic to metals then you may want one of the newly marketed hypoallergenic frames. Ask your optician what the frames are made of before making your final choice.
Hinges: When eyeglasses are taken on and off the part that endures the most stress are the hinges. If you are someone who has to take your eyeglasses off quite a bit then you may want to get a pair of frames that have flexible hinges. The better the quality of your hinges, the longer your glasses will last you.
There are a lot of things that you need to consider when picking out your glasses. Once you understand the issues that need to be met then you will have no problem at all deciding on the frames for you. Have fun and don't be afraid to ask questions.
Prescription eye glasses are used for vision correction as the combination of the lenses in your eyes and the lenses in your glasses will allow you to see properly. Those that have an astigmatism, are nearsighted or farsighted will require prescription eyeglasses. If you are nearsighted then you cannot see clearly far away and if you are farsighted then you cannot see clearly up close. As people age they may become both farsighted and nearsighted. In order to purchase prescription eyeglasses you will need to have an eye exam performed by an optometrist and then receive a prescription.
For those that have severe vision problems eyeglasses with lenses made of high index material can be the best as high index material eyeglasses will be very lightweight and provide better optics. Many times those with very bad eyesight will get headaches because their glasses are very heavy. High index lenses are an excellent option.
Aspheric lenses are also an excellent option for those that have very bad eyesight. Unlike more traditional lenses, aspheric lenses are more flat and thinner. This can be a benefit for your appearance as the lenses will not distort your face. Many times individuals that have extreme sight correction will have glasses that magnify their eyes or minify their eyes. With aspheric lenses your appearance will not be distorted.
There are also several types of coatings that can be applied to your lenses. Almost all prescription eyeglasses come with scratch resistant coatings. This coating makes any non glass lenses as scratch resistant as glass. There are anti reflective coatings to reduce glare, UV coatings to protect your eyes from UV light and other coatings that can make your eyeglasses last longer and look better.
Prescription eyeglasses can also have tinted lenses and the newest types of tinted lenses are photochromatic. Photochromatic lenses change color depending on the amount and type of light. When you are indoors the lenses will appear clear but if you should go outside on a bright sunny day the lenses will darken. Lenses can also be tinted strictly for aesthetic purposes.
Multifocal lenses are used for those that suffer from nearsightedness and farsightedness. The most common multifocal lenses are bifocals but you can also get trifocals and progressive lenses. Trifocals have three different lenses and progressive lenses have a smooth transition between the different lenses so that there is no line.
Some new developments include sunglasses with scratch resistance and smudge resistance. These sunglasses with Scotchgard protector reduce dirt, smudges, grease and water from adhering to the glasses. Progressive lenses now have an intermediate range instead of rather abruptly switching form one lens to the next.
Progressive lenses have developed further so that the transition between lenses is even smoother and less sudden. New forms of eyeglasses have been developed to reduce dry eyes and eye strain. By using wave front measurement prescription eyeglasses can be made to not only correct vision issues but also other high order eye problems.
