How do you know if you have power in your eyes?

Having the right power for your eyes is essential for optimal vision. The power in your eyes can be used to determine if you need glasses or contact lenses, if you need a new prescription, or if you have any other eye conditions that need to be addressed. But how can you tell if you have power in your eyes? There are several different tests and methods used to ascertain the power of your eyes. In this article, we will explore these different tests and methods so that you can know what to look for and if you have any power in your eyes.

Prescription Guide

If you already have a prescription, it is important to understand what each part of it means. A prescription generally includes your Cylinder (CYL) value and Axis. The Cylinder amount indicates the degree and direction of astigmatism, while the Axis indicates the direction of that astigmatism. The Cylinder value should always be present with the Axis and it will range from 0 to 180 degrees. If your prescription has either the Cylinder value or the Axis, but not both, it could mean your prescription is incomplete or incorrect.

Eye Chart

During an eye test, you will usually stand a set distance away from a “Snellen” chart, which is an eye chart that contains rows of increasing small letters. To determine the power of your eyes, you will need to read the different rows of letters without squinting. The smallest row you are able to read accurately is then used to measure your eye power.

Power Finder Tool

If you have your current reading glasses prescription handy, one easy way to measure your eye power is to take advantage of the Power Finder tool. This tool will ask you to enter your reading glasses prescription information and then it will provide a guide to help you determine your reading power.

Eye Pressure Symptoms

Average eye pressure should be neither high or low, so if you feel pressure in one or both eyes, you should have it checked out as soon as possible. The signs of high eye pressure might include headaches, dizziness, nausea, or blurred vision. However, the symptoms vary depending on the cause, and you should always consult your doctor if you experience any of these symptoms.

Myopia and Astigmatism

If you have been diagnosed with myopia (short-sightedness) and astigmatism (blurred or tailed images) in both eyes, there are certain values given in the prescription that indicate the calculated power needed to correct those eyes. This power is usually measured on a 1 to 5 scale, with 1 being the lowest level and 5 being the highest level of myopia.

Measuring Vision at Home

A home vision test is also an option if you want to measure your vision. To do this test, stand 40 centimeters away from the screen and either keep your current glasses on if you have them, or look through the lower part of your glasses if you have progressive lenses. Then, take note of the smallest line of letters on the screen that you were able to read without having to squint.

Eye Powers

Finally, if you could have powers with your eyes, there is an online quiz you can take to determine what kind of powers you have. This fun quiz will ask questions about what magical powers you think your eyes possess, such as elements control, future sight, and more.

No matter which method you use to determine if you have any power in your eyes, it is important to consult with an eye doctor to get an accurate diagnosis. By receiving a comprehensive eye exam and a follow up prescription, you can ensure that you have the right power for your eyes and are taking the necessary steps to maintain good eye health.
