Self-checks

Screen eye strain self-check

A short self-check on eye fatigue linked to long screen hours, glare and irregular breaks, written for people working from laptops and phones every day.

3-5 minutes15 questions

Answer based on a typical work week over the past two weeks, not a single long deadline. Include time on a laptop, a phone and any screens you use for work or entertainment. Be honest about how often you actually look away or blink, not how often you intend to.

Screen hours and breaksLighting and glareEye symptoms

This is an original set of observation questions, not a clinical vision test, and it cannot detect a refractive error, dry eye disease or any other eye condition. If you have blurred vision, eye pain, flashes of light or a sudden change in your sight, see an ophthalmologist rather than relying on this result.

A realistic work window

Two weeks smooths out one unusually heavy screen day and reflects your actual working pattern instead.

Screen habits, light and symptoms

Time on screens, the lighting you work in, and how your eyes actually feel are scored separately so you can see what to change first.

One clear next step per result

Each band points at something specific, whether that is adjusting your setup or booking an eye check.

Cafe lighting was not built for screens

A lot of remote work in Vietnam happens in cafes with large windows, bright outdoor light and glossy tabletops. That mix creates glare on laptop screens that forces the eyes to work harder to keep focus, often without the person noticing until a headache sets in by mid-afternoon. Sitting with a window directly behind or in front of the screen tends to be the worst position, even when the cafe itself feels comfortable.

Long hours without a real break

Remote schedules that stretch across time zones can mean back-to-back calls and typing sessions with few natural pauses. Eyes need regular breaks from close focus to reset, and skipping them for hours at a time is one of the most common causes of end-of-day strain, dryness and difficulty focusing on distant objects afterward.

Heat and air conditioning dry the eyes further

Air conditioning units running against the heat and humidity outside dry the air indoors, and that dryness affects the eyes as much as the skin. Combined with reduced blinking during focused screen work, this can leave eyes feeling gritty or tired well before the day is over, especially in enclosed offices and cafes with the air conditioning aimed directly at seating.

Before you start

Does a high score mean I need glasses?

Not necessarily. This result reflects habits and symptoms over two weeks, not a measurement of your vision. Only an eye exam with an optometrist or ophthalmologist can tell you whether your prescription has changed.

How often should I repeat this check?

Repeating it every few weeks is enough to see whether adjustments to lighting or breaks are helping. There is no benefit to checking daily.

When should I book an eye exam rather than just adjusting my setup?

Book an exam if symptoms persist after a few weeks of better lighting and breaks, if you notice blurred or double vision, or if you have not had your eyes checked in the past one to two years.
