As we age, our eyesight tends to deteriorate. It's always a good idea to check for visual acuity. For one thing, it helps to know whether you have any sort of vision problems or not.

If you want to monitor and maintain your vision, you might want to try one of these Android apps. Let's take a closer look at how they work.

1. Eye Patient

Eye Patient is an extremely useful app that can help with vision screening. This app allows you to track your visual acuity, contrast sensitivity, and color vision deficiencies easily.

The visual acuity tests within the app can help you understand how well you can read and see numbers, letters, or objects, distinguish colors, and how good your peripheral vision is.

A standard Snellen Chart, for instance, works by having you read letters on a chart at different distances. The chart is broken up into sections that represent varying levels of vision, so you can see how well you're doing.

With the Eye Health Score feature, you can learn more about symptoms or disorders such as macular degeneration, glaucoma, and other vision problems. Your score is based on different tests such as the Amsler Grid, Landolt-C charts, visual perception tests, and color vision screening, so you can determine the aspects of your vision that require attention.

The app allows you to access a vast archive of medical resources about eye care, from professional tests and screening procedures to treatments and surgeries, medicines, and useful insights into eye health and general medical conditions. You'll also get access to a directory of eye specialists near you.

Telemedicine tools such as Amsler Grid tests (which help you see any changes in your peripheral vision), and color vision charts (for testing color-blindness) are also available within the app for preliminary vision screening. The app is free to use.

2. Ishihara Color Blindness Test

Color vision deficiency can be caused by several factors including genetic predisposition and eye damage. If you suspect that you might have a problem with color perception, the Ishihara Color Blindness app can help.

Ishihara Plates usually consist of numbers, geometric shapes, and dots in different colors. They can be used to diagnose red-green color blindness. It is the most common type of color deficiency test, where you need to find a number hidden in a pattern of dots.

If you're spending a lot of time staring at computer screens, chances are you might also experience vision problems which can make it difficult to read or focus on work. We recommend using these browser extensions to relieve eye strain.

This easy-to-use app can even help you test for possible visual perception issues using Amsler Grid tests, as well as screen for astigmatism conditions.

To get started, simply follow the instructions for each type of test. It only takes a few minutes to complete, and you'll get immediate results. You can even get a few tips for better eye health as well as a couple of exercises to work on improving your eyesight. The free version of the app is supported by ads, which can be removed with a one-time upgrade.

3. Eye Test

According to the American Academy of Ophthalmology, nearly three million people aged 40 years and above suffer from low vision problems.

The Eye Test app is a useful vision screening app to help you check your visual acuity in a variety of settings. It comes with a battery of tests that range from simple to complex and age-appropriate ones. Some of these are Amsler Grid, Contrast Sensitivity, OKN Strip, and Red Desaturation tests.

You can use it if you're looking for an easy way to test yourself from time to time. It's also great for increasing your awareness of various aspects of eye health or vision issues. Contrast sensitivity tests, for instance, can measure how well you respond to changes in contrast levels across a series of images or patterns with varying levels of brightness between them.

In addition to testing your visual acuity, you can use some basic screening questions to test for glaucoma and other forms of vision loss. The app requires a one-time upgrade to access extra features and vision screening tests.

4. Eye Vision

This free app is a convenient tool that can be used to screen for visual acuity. It includes Snellen charts and letter tests that will help you test your ability to read small print efficiently and quickly. As with some other apps on the list, the app also has a color blindness test that allows you to check your color vision deficiency.

It's not uncommon for people to start experiencing vision problems such as blurry vision, age-related macular degeneration, or corneal disorders. But there are ways to improve your eye health. Some apps claim they can help improve eyesight with visual exercises and can be worth checking out.

Eye Care at Your Fingertips

While there are a variety of vision screening apps available, that's not to say you shouldn't try to get regular physical eye exams.

Some of these apps can be used as part of an eye exam, others give you preliminary results, and still others can help improve your eyesight or assist those with vision impairment. We hope that the list above helped you narrow down your search for an app that will work for you.
