Dark Circles Under Eyes: Causes, Treatment and When to Get Checked
Dark circles under the eyes are usually caused by genetics, thin or ageing skin, pigmentation, tiredness, allergies, sun exposure, eye rubbing or shadows from under-eye hollows. They are commonly cosmetic rather than dangerous. However, sudden one-sided discoloration, significant swelling, pain, vision changes or dark bruising after an injury needs prompt medical assessment.
What are dark circles under the eyes?
Dark circles, also called periorbital hyperpigmentation, describe skin beneath the eyes that looks darker than the surrounding face. The colour may appear brown, blue, purple or grey depending on skin tone and the underlying cause. Under-eye bags are different: they are swelling or tissue prominence, although bags can cast shadows that make circles look darker.
Common causes of dark circles
- Genetics and facial structure: Natural pigmentation, deep tear troughs and prominent blood vessels can run in families.
- Ageing: Skin becomes thinner and loses collagen, making vessels and hollows more visible.
- Fatigue: Lack of sleep may make the skin look pale and increase the contrast beneath the eyes, but sleep is not the only cause.
- Allergies: Nasal congestion can contribute to “allergic shiners.” Itchy eyes may also lead to rubbing and further pigmentation.
- Dermatitis and irritation: Eczema, contact dermatitis and unsuitable cosmetics can inflame the delicate eyelid skin.
- Sun exposure: Ultraviolet exposure can increase pigmentation, especially in people with medium to darker skin tones.
- Dehydration, smoking and lifestyle factors: These may make existing circles or puffiness more noticeable.
Are dark circles caused by an eye problem?
Most dark circles come from the skin, blood vessels, allergies or facial anatomy rather than the eyeball itself. An eye examination may be useful when circles occur with persistent itching, redness, watering, swelling, eye rubbing, headaches, blurred vision or suspected eyestrain. An optometrist can check the eyes and help decide whether referral to a medical doctor, dermatologist or allergy specialist is appropriate.
What may help?
- Keep a regular sleep routine and manage fatigue.
- Use a clean, cool compress for a few minutes when puffiness is present; do not place ice directly on the skin.
- Avoid rubbing or scratching the eyes.
- Use sunglasses and suitable broad-spectrum sunscreen around the orbital area, avoiding direct contact with the eyes.
- Identify and manage allergies with advice from an appropriate healthcare professional.
- Stop any cosmetic that causes burning, itching or rash.
- Do not apply bleaching agents, steroid creams, acids or unverified home remedies near the eyes without professional guidance.
Treatment depends on the cause. A dermatologist may discuss topical treatment, chemical peels, lasers or fillers for selected patients. These procedures have risks and should be performed only after an individual assessment, especially because the eyelid area is delicate.
When should you seek medical care?
Arrange prompt assessment if discoloration appears suddenly on one side, follows a head or eye injury, or occurs with severe swelling, pain, fever, eyelid drooping, double vision, reduced vision, a bulging eye or difficulty moving the eye. Dark bruising around both eyes after significant trauma can be different from ordinary dark circles and requires urgent medical evaluation.

Frequently asked questions
Does lack of sleep cause dark circles?
It can make existing circles more noticeable, but genetics, pigmentation, allergies, ageing and facial structure are also common causes.
Can eye allergies cause dark circles?
Yes. Nasal congestion and repeated eye rubbing can contribute to dark circles known as allergic shiners.
Can dark circles be permanently removed?
No single treatment works for everyone. Improvement depends on whether the main cause is pigment, visible vessels, swelling, dermatitis or structural shadowing.
Should I see an optometrist or dermatologist?
See an eye-care professional when dark circles accompany eye symptoms such as redness, itching, watering, pain or vision changes. A dermatologist is usually best placed to assess persistent skin pigmentation or cosmetic treatment.

Do You Also Have Eye Symptoms?
Dark circles are often a skin or lifestyle concern. If they occur with redness, itching, watering, pain, swelling or a change in vision, arrange a professional eye examination. Persistent pigmentation or cosmetic-treatment questions should be assessed by a qualified dermatologist; Vision Concern does not claim to provide cosmetic dermatology treatment.

Yes. Many visitors, particularly from Bangladesh and West Bengal (Kolkata), come to Nepal for cataract, retina, or other eye surgery at a hospital and also want new glasses, a general eye exam, or contact lenses at the same time, before or after their procedure. Vision Concern is an optical and eye-examination clinic, not a surgical hospital, so we work alongside hospitals such as Tilganga: we are happy to see you for glasses, contact lenses, or a routine check-up either side of your surgical treatment elsewhere.
No conversion is needed. Eyeglass prescriptions from Germany, France, the UK, the USA, China, Russia, and almost every other country use the same international format, SPH (sphere), CYL (cylinder), and AXIS, measured in diopters. Our opticians read this directly, so you can bring your prescription paper, a photo of it on your phone, or simply your current glasses, and we will use the same values. If your prescription is more than a year or two old, we recommend a quick, free re-check before we make your new pair.
Yes. Above roughly 3,000 metres, UV exposure increases sharply because of the thinner atmosphere and reflection off snow, and ordinary sunglasses (category 2-3) do not block enough UV to prevent snow blindness (photokeratitis). We recommend glacier glasses or category-4 sunglasses with side shields, and can fit these with your own prescription if needed. Vision Concern offers ZEISS polarized, UV400-certified sunglasses with prescription lenses, which we can prepare before you set off on your trek.
