You can use Printable Preschool Eye Charts to help your preschoolers learn about their eyesight. Depending on the age of your child, they will need to identify up, left, right, and down. These charts are not intended to replace an eye exam. Even though your child may have 20/20 vision, they may not be aware of underlying eye disease. Therefore, it’s important to take them to an eye doctor regularly for a complete eye exam.
What Are The 3 Three Types Of Eye Charts?
There are three types of preschool eye charts. Each type of chart tests for different things. For instance, one chart may say to screen at ten feet, while another has a line of twenty/XX numbers on the side. Each of these eye charts has different measurements, so it is important to understand what each one tests. You can learn more about each type by reading on! Below are some examples of the three main types.
Snellen letters and lines have unequal numbers of optotypes for each line. Because the letters are not standardized, they may overestimate visual acuity. The Sloan letter chart meets five national and international guidelines. This type of chart may lead to an over-referral rate. In addition, it may make the eye chart inappropriate for preschool children. A child may be misdiagnosed with amblyopia because the chart is not accurate enough for her eyesight.
How To Score Snellen Eye Chart?
You might have heard of the Snellen eye chart. This is a chart developed by Herman Snellen in 1862 to determine your visual acuity. Your vision is measured in terms of distance and the ability to read characters. Snellen charts measure your vision in terms of the distance you can see at a certain distance. Your prescription for glasses and contact lenses will be based on your vision on this chart.
The Snellen eye chart contains eight letters and is usually read from a distance of approximately 20 feet. Generally, the lettering on this chart is highly contrasted and is not representative of difficult visual tasks. Therefore, your visual acuity must be higher than 20/20 if you’re going to be working in a professional setting. This chart will also give you a fraction score. You will know if you’ve achieved perfect vision when your reading results are at or above 20/20.

Children aged four are at a critical developmental stage. They’ll be entering pre-school and will meet other children their own age. They’ll be more sensitive to their surroundings, so they’ll likely complain if they see something they don’t recognize. Luckily, doctors will give children a standard vision test using an eye chart at this age. This can help parents recognize problems early and make eye care easier and less expensive in the future.
