When a patient first consults with an optometrist about their vision problems, the optometrist will usually suggest using a Bernell red/green test book. The Bernell red/green filter books provide the most contrast between green and blue and are recommended most often by most eye doctors for certain patients with astigmatism. The test book is an excellent addition to every ophthalmologist's office, especially when viewing patients with astigmatism, strabismus, or those with amblyopia. These filters provide the highest contrast ratio of all three colors, making the overall color rendering of the document much clearer and more vivid than any printed document that is available for these eye conditions. The test book also serves as a reference during follow-up visits to increase eye-hand coordination, and eye relaxation.
Many people choose not to use the test booklet because they are unfamiliar with it. Most people will be able to get the idea of what each page of the booklet does. It is generally a blank white pages with a series of black bars, typically four in number, arranged in a vertical fashion. The top of the pages will have a number one and will contain a word or words to help you orient yourself with the document. The inside of each panel will have a different word or words that will help you complete your answers, which will be used later on during your consultation.
The pages of the test booklet will also have a series of scratch off or erase choices. Usually, you can choose from black, gray, and brown. The reason why people like this format is that it forces them to evaluate their own handwriting. The most difficult choices will be near the bottom of the page. Therefore, if you really want to find the answer, you need to really scratch off the choices that are at the bottom. Many people enjoy writing out the correct answer choices first and then choosing the correct word grouping to use to write their response.
If you choose not to use the scratch off or erase choices, then you may want to consider printing your actual answers on a separate piece of paper. This will not only be a good option if you have a deadline. You could also work with different color ink to make your answers stand out. Another option that you could consider is using a sticker to label your answer sheet.
When the time comes for the actual examination, you may find that you are in a hurry. In this case, the best thing that you can do is go back and answer the questions that you are confused about. To do this, you will want to take a few minutes to go back and re-read your answer choices. After about seven or eight questions, you will be certain as to which questions you know the correct answers to. You should also make a list of all the questions you were confused about so that when you do go back to them, you will have them handy to go back to and review.
Another option that you may want to consider is using a pencil for your scratch paper. Even though it may seem like a waste of time, if you do have a few extra minutes, it can be extremely helpful to go back over your answers with a pen so that you can mark-up the correct answers. After you have marked the correct answers, then you can take your completed scratch paper to an office supply store and have the appropriate pencil sharpened. This will make it easier to write on your booklet.
It is important to remember to go back over your answers whenever you feel it is necessary. This will help you to make sure that you are completing the work correctly. Remember, a Test Booklet is not a play ground! You should be completely thorough when you complete the booklet or it will become an embarrassing thing for you to have to deal with at the end.
After you have written your booklet, then you will want to print it out. Then you will want to either send it by regular mail or use one of the many internet services that will print it out for you for a small fee. You will also want to put your answers directly on the cover so that students can easily go back over their answers and mark-up the incorrect answers where necessary.
