I'm not talking about seeing. I'm talking about look. Because there's a world of difference between the two, and your smartphone is about to reveal it to you.
Imagine this: you're reading this text right now, but what if I told you that maybe you're not seeing all the colors you should?
Or is that slight difficulty focusing on distant signs not just fatigue? We live glued to screens for hours, mercilessly straining our eyes, and paradoxically, those same screens can become our first ally in discovering how well—or poorly—we are seeing the world.
Technology has democratized something you could previously only do in a doctor's office: have your vision checked. And the best part is, you have it in your pocket.

The silent revolution of visual health
Previously, you had to wait months for an eye appointment.
Then pay for a consultation.
Then discovering that perhaps it wasn't so urgent.
Or maybe it was, but you arrived too late.
Times have changed. Vision assessment apps don't replace specialists—let's be clear about that—but they do function as an early warning system. Like that friend who tells you, "Hey, you should get that checked out," before the problem becomes serious.
The fascinating part? These apps use the same scientific principles that optometrists have used for decades. The difference is that now they're optimized for the screen you look at 150 times a day.
Eye Care: Your Personal Eye Coach
Think of Eye Care as that personal trainer you never had for your eyes.
The application understands something fundamental: Prevention is smarter than cure..
It's not just about measuring how well you see now, but about protecting how you'll see tomorrow. Eye Care incorporates exercises specifically designed to combat computer vision syndrome, that set of discomforts that appear after spending hours in front of screens.
Did you know that you should rest your eyes every 20 minutes?
Probably yes.
Do you do it?
Probably not.
Eye Care becomes your external memory. It reminds you to blink—yes, when you're concentrating you blink 66% less—and guides you through exercises that seem simple but are incredibly effective: tracking moving objects, shifting focus between near and far distances, and relaxing your eye muscles.
The interface is intuitive because it understands that nobody wants to complicate things with confusing menus when the goal is precisely to reduce eye strain. You open the app, follow the instructions, and in five minutes your eyes will thank you.
But here's the really interesting part: Eye Care also includes basic visual acuity tests. Those letters that gradually decrease in size, the same ones you see at the ophthalmologist's office, but adapted for your screen. It's not a medical diagnosis—it never will be—but it is a valuable reference point to know if you should be concerned or if everything is fine.
Color Blindness Checker: When red isn't red
Now let's talk about something that affects millions of people without them knowing it.
Color blindness.
Approximately 1 in 12 men and 1 in 200 women have some degree of color vision deficiency. Many go their entire lives unaware of it, unconsciously compensating by memorizing that the overhead traffic light means "stop" not because of its color but because of its position.
Color Blindness Checker unravels that mystery.
The app uses the famous Ishihara plates, those circles filled with colored dots where numbers or shapes are hidden. If you have normal color vision, you see them clearly. If you're colorblind, they simply… disappear. Or you see different numbers.
It's a revealing experience.
Almost disturbing.
Because suddenly you realize that other people are seeing a slightly different world than you. Or that you are seeing a different world than they are.
The app doesn't just diagnose. It explains what kind With color blindness, you could have: protanopia (difficulty with red), deuteranopia (difficulty with green), tritanopia (difficulty with blue). Each type has its own characteristics, daily challenges, and solutions.
And here's the brilliant part: Color Blindness Checker includes simulators that allow people with normal vision to see the world as someone with color blindness sees it. You can take a photo and apply different filters. It's educational, empathetic, and incredibly useful for designers, artists, or simply for better understanding someone close to you.
The app also offers practical tips for navigating a world designed primarily for people with full color vision. From choosing clothing combinations to adjusting your device settings to improve contrast.

If Eye Care is your trainer and Color Blindness Checker is your color blindness detector, then Vision Test It's your portable medical exam.

Much further.
Vision Test offers a comprehensive battery of tests that evaluate different aspects of your vision. It doesn't just ask if you can read small print. It wants to know more. as You see, with what precision, under what conditions.
The visual acuity test here is more sophisticated. It adjusts the size, contrast, and recommended viewing distance. It asks you to physically measure the distance between your eyes and the screen for proper calibration. Details matter when it comes to accuracy.
But it doesn't end there.
Vision Test includes testing for astigmatism, a visual defect where the cornea has an irregular curvature. The test is simple but effective: radial lines emanating from a center. If some lines appear sharper or darker than others, it could indicate astigmatism.
There's also the famous Amsler grid, This test is crucial for detecting problems in the macula, the central part of the retina responsible for detailed vision. You look at a central point on a grid, and if the lines appear wavy, distorted, or with missing areas, it's a warning sign that you shouldn't ignore.
The app assesses your contrast vision, your ability to distinguish objects that don't have clearly defined edges. This is especially important for activities like driving at night or in fog.
And yes, it also includes color perception tests, although not as specialized as Color Blindness Checker.
The most valuable aspect of Vision Test is how it organizes and presents the results. It leaves no room for doubt. It provides clear graphs, understandable explanations, and most importantly, recommendations on when you should consult a specialist.
