Have you ever felt tired, flat, or overwhelmed in the darker months, like we are now in the UK and January is always a tough month to get through but we are nearly there! If the answer is yes, then you are not imagining it. While Blue Monday itself can be a medical diagnosis and the link between how we feel and how our eyes feel (and see) is very real. It is different to Monday Blues.

This article we will look at the proven research behind eye health and mood and the simple eye-care habits that can help you feel better day-to-day.

First: Is Blue Monday Real?

First of all, Blue Monday is different to Monday Blues. The idea of Blue Monday (often described as the most depressing day of the year, 3rd Monday of January) isn’t recognised as a clinical concept. But it can be a useful prompt to check in with yourself, especially in winter, when many people experience low mood. Whereas “Monday blues” refers to the feeling of reluctance to return to work after the weekend.

Vision Problems and Depression/Anxiety

Research consistently shows that people with vision impairment are at higher risk of depression and anxiety.

A systematic review and meta-analysis published in Scientific Reports (nature.com and JAMA Ophthalmology) found a notable prevalence of depression among patients with eye disease.

Why this matters for everyday life: when your vision is reduced, it can affect independence, confidence, social connection, work, and hobbies all of which can influence mood.

Dry Eyes, Screen Fatigue and Your Mental Wellbeing

Dry, irritated eyes can make you feel drained and snappy. There’s also some evidence that dry eye disease is associated with depression and anxiety but research in this area is still limited so let’s not jump to conclusion.

This doesn’t mean dry eye causes depression, but the association maybe enough that it’s worth looking into, especially if they’re affecting your quality of life. It is more like the link between the two so, if dry eyes is a nuisance to you then it may impact your mood and therefore, your quality of life.

Light, Winter Mood and Where Your Eyes Come

In winter, we get less daylight and that can affect circadian rhythms (your sleep-wake cycle) and mood.

Bright light therapy has evidence behind it for seasonal affective disorder (SAD) and is also being explored beyond seasonal depression.

Signs Your Eyes Might Be Affecting Your Mood

  • You’re getting headaches or eye strain most days
  • Your eyes feel dry, gritty, or watery after screens
  • You’re squinting more than usual (even with glasses)
  • You’re avoiding reading, driving, or social plans because it feels harder
  • You feel more irritable or exhausted after screen-heavy days

7 Eye Health Habits That Can Support a Better Mood

  1. Book an eye test (and actually wear the prescription) Uncorrected vision can quietly add stress to your day. If you’re overdue, get booked in.
  2. Reduce digital eye strain with the 20-20-20 rule. Every 20 minutes, look 20 feet away for 20 seconds. Small habit, big relief.
  3. Treat dry eye symptoms early. If your eyes feel dry or irritated most days, don’t just push through.
    An optician can help you choose lubricating drops (often called artificial tears). If symptoms persist, ask for a proper dry eye assessment.
  4. Go outside during the day (yes, even when it’s grey) Daylight exposure can support your body clock and energy levels. A short walk counts too and fresh air is always a good idea.
  5. Consider bright light therapy if your mood is low during winter. If you suspect SAD, speak to a healthcare professional. If you try a light box, use one designed for SAD and follow guidance on safe use. In the UK, the NHS website actually covers this as a topic.
  6. Prioritise sleep (your eyes feel it first) Poor sleep can worsen dry eye symptoms and make everything feel harder. Aim for a consistent wind-down routine.
  7. Keep your eye area comfortable (especially if you wear makeup) Remove eye makeup gently, avoid rubbing, and keep eyelids clean particularly if youre prone to irritation.
