Test preview

The test structure is shown below. The full test opens after confirming contact details.

1 AAO / NEI warning-sign based triage

Urgent eye symptom check

A short set of questions to separate routine booking from symptoms that should be reviewed quickly.

Information
This block does not diagnose. It helps route the patient safely to a doctor or quick clinic contact.
Instruction
Mark symptoms that are present now or appeared suddenly. If at least one urgent sign is selected, the system will show priority booking or a call option.

Did vision in one or both eyes suddenly become much worse?

Especially if it happened within hours or 1–2 days.

Is there severe eye pain, intense redness, or light sensitivity?

These symptoms should not usually wait for a routine visit.

Have you noticed flashes, many new floaters, or a curtain-like shadow?

This is a reason to contact the clinic quickly.

Was there an eye injury, burn, or chemical exposure?

This situation needs quick professional assessment.

2 Snellen visual acuity chart

Distance visual acuity check

A preliminary check of how clearly you see symbols at a distance.

Information
Accuracy depends on screen size, distance, lighting and calibration. This is not an eyeglass prescription.
Instruction
Stand at the recommended distance from the screen, cover one eye, and select the smallest row you can read confidently. Repeat for the other eye.

Right eye: what is the smallest row you read confidently?

If unsure, choose the previous larger row.

Left eye: what is the smallest row you read confidently?

Cover the right eye without pressing on it.

3 Astigmatic dial / fan dial subjective refraction target

Astigmatism sign check

A radial-line target: with astigmatism, some lines may look darker, sharper or blurrier.

Information
This is only a screening check. Astigmatism is measured accurately during an in-office refraction.
Instruction
Look at the center of the target with each eye separately. Select whether all lines look similar or certain directions stand out.

How do the dial lines look?

Check each eye separately.

4 Amsler grid central vision monitoring

Amsler grid

Helps notice distortion, dark spots or missing areas in central vision.

Information
If lines are distorted, missing, or a dark spot appears, booking with an ophthalmologist/retina specialist is recommended.
Instruction
Wear reading glasses if you use them. Cover one eye, look at the center dot and note whether the lines are straight and complete.

What do you see on the grid?

Check the right and left eye separately.

5 Ishihara-style pseudoisochromatic color plate screening

Preliminary color vision check

A screen-based check inspired by pseudoisochromatic plates: the user should identify a number on a colored field.

Information
Displays, night mode and brightness can distort the result. A professional test is required for a reliable conclusion.
Instruction
Look at the image at normal screen brightness and choose the number you see. Do not change color settings during the test.

What number do you see on the color plate?

This is the module’s own test illustration, not an original Ishihara plate.

6 Dry eye symptom screening

Dry eye symptoms

A questionnaire about burning, gritty sensation, fluctuating clarity and discomfort often associated with dry eye.

Information
The questionnaire does not identify the cause of dryness. The doctor may recommend tear-film tests.
Instruction
Rate how often these symptoms have bothered you recently. Answers help suggest the right consultation or diagnostic service.

Burning, stinging or gritty feeling in the eyes

0 — none, 3 — often / strong

0 — none 3 — often / strong

Vision fluctuates between clear and blurry, especially while reading or using screens

Select how often it happens.

0 — none 3 — often / strong

Redness, tearing or discomfort by the end of the day

0 — none, 3 — often / strong

0 — none 3 — often / strong
7 AOA computer vision syndrome / digital eye strain

Digital eye strain

A questionnaire about eye fatigue, headache, dryness and focusing difficulty after computer or smartphone use.

Information
Symptoms may relate to refraction, dry eye, lighting, screen position or work habits.
Instruction
Answer based on a typical working day. The result helps suggest a preventive exam, refraction check or consultation on screen-related load.

How many hours per day do you usually use screens?

Include computer, phone and tablet use.

Headache, eye strain or slow focusing after screen use

0 — none, 3 — often / strong

0 — none 3 — often / strong

Does it improve after taking a break from the screen?

This may indicate screen-related strain.
