Interactive Eye Tests – Part 3

Tumbling E Visual Acuity

Identify the direction of E letters at decreasing sizes — digital Snellen chart.

View from 40cm. Test each eye separately.

Red Desaturation Test

Compare red vividness between eyes. May help detect optic nerve issues early.

Look at the red circle. First right eye, then left. Is the color equally vivid?

Pupil Response Test

Observe your pupil reaction as screen brightness changes.

Look closely at screen. Brightness will change — notice your pupils constricting and dilating.

Depth (Stereo) Perception Test

Test whether both eyes work together to create depth perception.

Look at the shapes. Try to identify which circle appears 'closer'.

Motion Sensitivity Test

Measure your ability to detect small, slow movements.

Find the moving dot among static ones and click it.

Flicker Threshold Test

Test your flicker detection threshold. Low threshold may indicate neurological issues.

Can you see the box flickering (flashing)?

Pattern Recognition Speed

Measure how fast you can find the different shape in a pattern.

Find the odd one out as quickly as possible and click it.

Double Vision (Diplopia) Check

Simple test to check for double vision.

Focus on the dot. Hold your finger 15cm away while looking at screen. Your finger should appear double.

Color Hue Discrimination

Test your ability to distinguish very similar color hues.

Find the slightly different color box in each round.

Visual Memory Test

Test your short-term visual memory — an indicator of eye-brain coordination.

Remember the briefly shown pattern and select the correct one.
