What are all the sight words
What Are Sight Words? Get the Definition Plus Teaching Resources
When you’re a new teacher, the number of buzzwords that you have to master seems overwhelming at times. You’ve probably heard about many concepts, but you may not be entirely sure what they are or how to use them in your classroom. For example, new teacher Katy B. asks, “This seems like a really basic question, but what are sight words, and where do I find them?” No worries, Katy. We have you covered!
What’s the difference between sight words and high-frequency words?
Oftentimes we use the terms sight words and high-frequency words interchangeably. Opinions differ, but our research shows that there is a difference. High-frequency words are words that are most commonly found in written language. Although some fit standard phonetic patterns, some do not. Sight words are a subset of high-frequency words that do not fit standard phonetic patterns and are therefore not easily decoded.
We use both types of words consistently in spoken and written language, and they also appear in books, including textbooks, and stories. Once students learn to quickly recognize these words, reading comes more easily.
What are sight words and how can I teach my students to memorize them?
Sight words are words like come, does, or who that do not follow the rules of spelling or the six types of syllables. Decoding these words can be very difficult for young learners. The common practice has been to teach students to memorize these words as a whole, by sight, so that they can recognize them immediately (within three seconds) and read them without having to use decoding skills.
Can I teach sight words using the science of reading?
On the other hand, recent findings based on the science of reading suggests we can use strategies beyond rote memorization. According to the the science of reading, it is possible to sound out many sight words because they have recognizable patterns. Literacy specialist Susan Jones, a proponent of using the science of reading to teach sight words, recommends a method called phoneme-grapheme mapping where students first map out the sounds they hear in a word and then add graphemes (letters) they hear for each sound.
How else can I teach sight words?
There are many fun and engaging ways to teach sight words. Dozens of books on the subject have been published, including the much-revered Comprehensive Phonics, Spelling, and Word Study Guide by Fountas & Pinnell. Also, resources like games, manipulatives, and flash cards are readily available online and in stores. To help get you started, check out these Creative and Simple Sight Word Activities for the Classroom. Also, check out Susan Jones Teaching for three science-of-reading-based ideas and more.
Where do I find sight word lists?
Two of the most popular sources are the Dolch High Frequency Words list and the Fry High Frequency Words list.
During the 1930s and 1940s, Dr. Edward Dolch developed his word list, used for pre-K through third grade, by studying the most frequently occurring words in the children’s books of that era. The list has 200 “service words” and also 95 high-frequency nouns. The Dolch word list comprises 80 percent of the words you would find in a typical children’s book and 50 percent of the words found in writing for adults.
Dr. Edward Fry developed an expanded word list for grades 1–10 in the 1950s (updated in 1980), based on the most common words that appear in reading materials used in grades 3–9. The Fry list contains the most common 1,000 words in the English language. The Fry words include 90 percent of the words found in a typical book, newspaper, or website.

The Dolch Sight Words list is the most commonly used set of sight words. Educator Dr. Edward William Dolch developed the list in the 1930s-40s by studying the most frequently occurring words in children’s books of that era. The list contains 220 “service words” plus 95 high-frequency nouns. These words comprise 80% of the words you would find in a typical children’s book and 50% of the words found in writing for adults. Once a child knows this list of words, it makes reading much easier, because the child can then focus his or her attention on the remaining words.
The Dolch words are commonly divided into groups by grade level, ranging from pre-kindergarten to third grade, with a separate list of nouns. There are a total of 315 Dolch Sight Words.

Is it possible to see better than one: how visual acuity is determined.
From childhood, many remember the words of the famous song: "and the eye is like an eagle's." These birds of prey have amazing visual acuity and can see prey from great heights. Their vision is 3-4 times greater than the capabilities of the human eye. In this article, we will tell you what visual acuity is, what is the best vision a person can have, and how to determine visual acuity at home.
What is visual acuity
Visual acuity is the ability of the eye to distinguish separately two objects located at a minimum distance from each other. In simple words, this is how well we see objects, inscriptions and people at a distance. The greater the distance, the higher the visual acuity.
Visual acuity allows us to see well people, objects and inscriptions at a distance.
Special retinal cells called cones allow us to see objects in detail. They are located in the central part of the eye in the macula. The diameter of the cones determines how well we can see far away.
The smaller the cone diameter, the higher the visual acuity. Our eye perceives two objects separately if the image of these objects falls on two different cones, between which there is one inactive, sleeping cone.
Visual acuity is the simplest indicator of the state of the visual system. Often people turn to an ophthalmologist when they notice that they do not see as well as before.
Sharpness and clarity of vision are not the same thing. For example, people with cataracts may have visual acuity of 90-100%, but the quality of vision will be poor: fog, faded colors.
How visual acuity is determined
To determine visual acuity, tables with optotypes are used - letters or signs of various sizes. The first such table was created in 1862 by the Dutch ophthalmologist Hermann Snellen.
Tables of Golovin and Sivtsev
In Russia, visual acuity is determined using the Golovin and Sivtsev tables, named after their creators, Soviet ophthalmologists.
The Sivtsev table consists of seven letters of the Russian alphabet of various sizes, arranged in 12 rows. You know this table well - it begins with capital letters "Sh" and "B". You could also see Golovin's table in the ophthalmologist's office; it consists of Landolt rings - circles with gaps resembling the letter "C".
On the left in the tables, the distance from which a number of signs are visible with normal visual acuity is indicated. The first row of the table should be visible from a distance of 50 m, the second - from 25 m, and the tenth - from 5 m.
Previously, the table was printed, and the patient had to be at a distance of 5 m from it. Now more often they use an ophthalmic sign projector - with it you can check visual acuity at any distance from the screen and carry out other tests, for example, to identify the dominant eye.
Visual acuity numbers
On the right in the tables are the numerical values of visual acuity.
In Russia and Europe, the value of 1.0, or 100%, is accepted as the norm. The standard visual acuity of 1.0 is next to the tenth line. The magnitude of visual acuity decreases with the number of lines. According to the table, if a person sees line 9, his visual acuity is 0.9; eighth line - 0.8; and the first is 0.1.
In Russia, the standard value of 1.0 or 100% is accepted as the norm of visual acuity.
How is the test
The eyes are checked one by one. Usually start with the right eye. The left eye is closed with an opaque white flap. The eye must be covered, but not closed, otherwise it will affect the result.
Visual acuity is determined by the row where all the signs were correctly named. You can make one mistake in rows 3 to 6, and two in rows 7 to 10. In this case, the doctor will make a note that visual acuity is incomplete. You need to recognize a letter or sign within 2-3 seconds - more time will already indicate a deviation.
If visual acuity is less than 0.
1
If a person does not see the top line of the table, then his visual acuity is less than 0.1. Then either the patient comes closer to the table until he sees the first line, or the ophthalmologist, showing the fingers of his hand, approaches the patient himself until he can name the number of fingers. The distance is then measured and the value calculated.
Visual acuity test with light
If the patient does not see the fingers near the face, then the perception of light is checked. The doctor uses an ophthalmoscope, a device similar to a flashlight. The patient must determine which side the light is on. If he can do this, visual acuity is equal to light perception with the correct light projection. If not, then visual acuity is light perception with incorrect light projection.
When the patient cannot distinguish between light and dark, his visual acuity is zero.
Natural and absolute visual acuity
When checking natural visual acuity, it is determined how the eye sees without lenses and glasses.
In the event that a person sees less than 10 lines, an additional study is carried out to determine the absolute visual acuity to determine how well a person can see with glasses or lenses. To do this, put on special glasses with removable glasses and select a correction that gives maximum visual acuity.
What is the best vision
There are 12 rows in Sivtsev's table, but only 10 are used for a standard visual acuity test. So what are the remaining two rows? It's super vision!
Visual acuity of 1.0 is a conditional standard. In some people, the vision exceeds one - they see the eleventh and twelfth lines of the table. In numerical values, the sharpness can be 1.2 - 120%; 1.5 - 150%, or even 2.0 - 200%.
The record for the sharpest vision was set at 1972 in Germany. The person with the best eyesight in the world is Veronica Seider. At that time, the girl was 21 years old. Veronica was able to see in detail the face of a person from a distance of 1600 meters.
This is 20 times more than the average person. Although less than that of an eagle: the bird sees prey from a distance of 3000 meters.
How to check visual acuity at home
You can determine visual acuity at home. How to do it:
- Print the Sivtsev table on three A4 sheets.
- Hang on the wall at eye level.
- Move 5 m away from the table.
- Cover the left eye with the palm of your hand.
- Start reading table rows.
- Open the left eye, cover the right eye with the palm of your hand.
- Reread table rows.
Bottom line: the row that you can read last is an indicator of your visual acuity.
Online check at monitor
You can conduct a quick online test at a computer monitor. Look at the image below. Who do you see?
A person with normal vision will see Albert Einstein, and a person with myopia will see Marilyn Monroe. If you move away from the computer screen for some distance, then the great scientist will turn into a famous actress.
What is the "leading eye"
At home, you can test to identify the dominant eye - the eye that dominates the process of seeing. The brain perceives information coming through the dominant eye as dominant. It is like the dominance of the right hand or the left hand. In most people, the right eye is dominant, which does not always coincide with the main hand.
Knowing your leading eye is important for sports that require aiming: archery, darts, and others. It is also necessary before surgical treatment of cataracts, when performing laser correction and choosing lenses. Most often, the Miles test is used to determine the leading eye.
Miles Test
- Choose a small, stationary object, such as a wall clock.
- Stretch your arms out in front of you and put your palms on top of each other so that there is a small hole between them. To do this, put your thumbs on top of each other, and connect the rest of your fingers together.
- The object must be inside the hole.
- Keep arms outstretched and still.
- Then close each eye in turn.
Bottom line: the one in which the image remains in the field of view is the leading one.
Home methods of eye examination will not replace the diagnosis by a specialist. To get accurate and detailed information about your vision, it is better to undergo a comprehensive diagnosis of the visual system.

You should understand that an examination at home is not a substitute for a complete eye examination by an ophthalmologist.
It is rather an auxiliary tool that allows you to detect changes in the state of your vision in time and understand that it is time to seek help from a specialist.
Only timely detection of violations and their prompt correction can minimize harm to health and protect the body from possible negative consequences. It is recommended to visit an ophthalmologist at least once a year even if nothing bothers you. But this is primarily your area of responsibility - to monitor the state of your vision and quickly respond to the changes noticed.
Therefore, the methods proposed by us are not a substitute for a face-to-face visit to a specialist, but can be used as an additional tool for self-diagnosis!
What will the eye test at home show?
The same applies to the diagnosis of various disorders - myopia, hyperopia and other vision pathologies. Only a doctor can determine this, and the diagnosis will be made after a comprehensive examination of the organs of vision.
But you can suspect that you have these disorders based on the results of a home check and contact a specialist to confirm or refute the diagnosis.

Visual acuity test according to the Sivtsev table
The well-known table with letters was developed by the Soviet ophthalmologist Dmitry Sivtsev, it is also perfect for home checking.
The table includes 12 lines with letters of different heights. The top line is the largest, the lower the line, the smaller the size of the letters. Accordingly, the more lines a person clearly sees, the sharper his vision.
Two values are indicated next to each line - D and V. The first, D, indicates the distance from which a person with good eyesight is able to clearly see all the letters of the selected line. The value of V characterizes visual acuity.
You will need a printed table for verification. A4 format is enough, but it is important to first change the page settings to landscape orientation.
The table must be hung on the wall, while focusing on the 10th line - it should be at the level of your eyes. It is better to dim the light in the room, and additionally illuminate the table. Step back about 5 meters and proceed to the vision test.
If you are unable to print, you can check your visual acuity online: display the test chart for vision on the monitor and step back 5 meters. If possible, move the computer higher so that the table is at eye level.
If you have not had vision problems before, start checking immediately from line 10 - this is what people with 100% vision see. Can't make out some or all of the letters? Smoothly move along the table above, until the line on which you can clearly distinguish all the letters. Each eye must be checked separately, it is better to close the second eye with the palm of your hand during the test, but make sure that the covered eye does not close.
With 100% vision there will be the following indicators: no more than one error in the rows V=0.
3-0.6 and no more than two errors in the rows V>0.7. If you make more mistakes in any of the rows, visual acuity is reduced. In this case, it is worth contacting an ophthalmologist as soon as possible for a complete diagnosis.

Lines 11 and 12 are not indicative. If you can clearly see all the letters of these lines, then you have an excessively high visual acuity, but you can talk about this only if you examine the letters without strain, squinting and excessive eye strain. This condition is not a pathology, but rather indicates the features of your vision or the structure of the eyes.
How to prepare for the test?
Give your eyes a proper rest before the test – spend at least half an hour without a computer, tablet, phone or book. It is better to do simple household chores that do not require significant visual load.
If you wear glasses or lenses, it is recommended that you remove your correctives at least 10 minutes before the test.
How often should I repeat the home visual acuity test?
If you do not experience any change in your visual acuity in your daily life, check once every one to two months.
Peculiarities of testing in children
If you want to test your child's vision, you can find a special analogue of the Sivtsev table on the Internet, where pictures are shown instead of letters. However, in the case of children, we strongly advise you to visit an ophthalmologist and not rely on the results of a home vision test.
Duochrom test for visual impairment
The duochrom test allows you to suspect nearsightedness (myopia) or farsightedness (hypermetropia) using a two-color image. This check can be carried out online, on a computer or phone. If you wear glasses or lenses, stay in them for the duration of the test - the test can also show if your corrective is correct.

The distance to the monitor during the eye test should be 50-70 cm.
Determine the desired distance and look at the picture: if the letters on a green background seem clearer to you, this may indicate the presence of farsightedness. And vice versa - clearer letters on a red background may indicate the presence of myopia.
Let us clarify once again: a home vision test in front of a computer will not replace a full-fledged examination by an ophthalmologist, so even if you have passed the test and suspected any violation, the specialist will have the final say.
How to prepare for the test?
Give your eyes a little rest - relax, close your eyelids and sit for at least 5-7 minutes. If you are using corrective aids, remain in them for the duration of the test.
Testing only makes sense if you are in good health. Any ailment - headache, fever or illness - can affect the results.
How often should I repeat the home test for myopia/farsightedness?
This test method does not require frequent repetition.
It is enough to pass the test a couple of times a year. It is also possible to take the test if you have changed the means of correction, but only after the vision has adapted to the new glasses or contact lenses.
Home astigmatism test
The simplest and most straightforward home astigmatism test is the Siemens star. Expand the image to full screen, step back 3-5 steps and start checking. Each eye must be tested separately, as in the case of a visual acuity test, cover one eye with the palm of your hand, but do not squint.
Normally, a person sees a circle with both eyes. However, if you have astigmatism, you may notice during inspection that the picture has changed shape to an ellipsoid. With this visual disturbance, it seems that the rays blur and overlap each other, not reaching the center.
Sometimes a person notices an inversion: the background becomes black and the rays become white. This effect can also indicate the presence of astigmatism.
However, various factors can affect test results, including lighting and eye moisture! Therefore, you cannot rely on an online test alone; it is necessary to confirm the diagnosis at an ophthalmologist's appointment.

How to prepare for the test?
Astigmatism should be checked in the morning. Corrections must be removed at least 10 minutes before the test. The room should be sufficiently lit, and the brightness of the monitor should be dimmed to medium values.
How often should the test be repeated?
Misperception of the Siemens star can indicate not only astigmatism, but also other visual impairments. You should repeat the test every few months, but make sure that the conditions - lighting, distance from the monitor, well-being - do not change.
What to do if you suspect vision problems after a home check
Visit an ophthalmologist as soon as possible and check your visual acuity and other parameters on professional equipment. As we have already said, it is simply impossible to check your eyesight normally at home. To diagnose or rule out possible problems, the doctor assesses not only your visual acuity, but also the general condition of your eyes
To exclude the presence of vision problems or respond in time to their appearance, undergo a preventive examination by an ophthalmologist at least once a year.
