What vision type do you have? Do You Know? Millions of people have vision problems that present unique challenges and experiences with how they see the world. Some of the most common vision types out there involve nearsightedness, farsightedness and astigmatism. However, there are also others that have diseases that affect their vision, or rare vision conditions such as color blindness. Let us help you discover the different vision types there are, what the most common include and how you can correct certain vision problems!
Peripheral vision, depth perception, eye coordination, color vision, and focusing all contribute to how your quality of your vision is calculated. Visual acuity is determined with the use of a Snellen Eye Chart. You know, those charts in the doctor’s office that start with a large E? They contain 11 rows of letters decreasing in size.
These numbers determine your visual acuity based on what you can see at a distance. Consider the following breakdown of the numbers:
Contrary to popular belief, 20/20 vision does NOT equal perfect eyesight. 20/20 is the standard baseline used for visual acuity tests.
Refractive errors are very common. An error results from the shape of your eye not allowing light to bend correctly to produce a sharp image. The main types of refractive errors are:
To determine the severity and type of your refraction errors, during your eye exam your doctor will use a tool called a phoropter in front of your eyes and present you with a series of lens choices. You will be asked which of the two lenses in each choice (“1 or 2,” “A or B,” for example) make the letters on the wall chart sharpen.
Your answers will be used to help measure the amount of nearsightedness, farsightedness and/or astigmatism you have. Eyeglasses or contact lenses will then be prescribed to correct your refraction issues.
Vision is a delicate science with over 100 tests to assess your eye health. Some tests evaluate eye coordination while others examine depth perception, color blindness, peripheral vision or awareness, focusing ability and more.
Some eye conditions, like glaucoma, can be caught early during a comprehensive eye exam and save your vision. The slight changes that occur to vision over the years should never be ignored; they can indicate more serious medical conditions.
