Drunk Eyes, Whiskey Nose, and Other Physical Signs of Drinking

Blood alcohol can keep rising after the last drink, even while they are unconscious.

What are drunk eyes?

“Drunk eyes” is slang for how eyes look after drinking: red or bloodshot, glassy or watery, lids drooping, focus slow. Police add one more: a small jerking of the eyes as they look to the side. It is the only eye test in the roadside battery NHTSA has validated for alcohol.

The rest are what tired, allergic, or crying eyes look like too. Physical signs can tell you something is worth asking about. They cannot tell you how much someone drinks, or whether they have a problem.

Why does alcohol make your eyes red?

Part of the answer may be in the tears. In a 2012 study in Ophthalmology, researchers gave 10 healthy men a measured dose of alcohol in the evening and compared them with 10 who did not drink. Alcohol showed up in their tears that night. Their tear film broke up faster, and by 6 and 8 the next morning the surface of the eye showed more damage on staining, even though no alcohol was left to measure. The study measured the tear film, not redness, but MedlinePlus lists eye dryness among the causes of bloodshot eyes.

Across studies, a 2016 meta-analysis of 10 case-control and cross-sectional studies linked drinking with modestly higher odds of dry eye disease.

Other routes have nothing to do with alcohol. Rosacea reaches the eyes in about half of the people who have it, per the American Academy of Dermatology. Our guide to what different drugs do to the eyes covers cannabis, the other common reason for red eyes at a party.

Do drunk eyes have dilated pupils?

Not in a way anyone can use. When researchers tested pupil response, balance, and other measures in people given low doses of alcohol, the differences between people swamped the changes alcohol caused. Pupils are a strong clue for opioids, which shrink them to pinpoints. For drinking itself, they say almost nothing, although MedlinePlus lists enlarged pupils among the signs of alcohol withdrawal.

The eye test police use: horizontal gaze nystagmus

Nystagmus is an involuntary jerking of the eyes. Everyone’s eyes jerk slightly when pushed as far to the side as they will go. Alcohol makes that jerk bigger, makes it last, and makes it start sooner, at a smaller angle. That is the basis of the horizontal gaze nystagmus (HGN) test, the first of the three standardized field sobriety tests in the National Highway Traffic Safety Administration (NHTSA) curriculum. The other two are the walk-and-turn and the one-leg stand.

An officer moves a penlight across the person’s view and looks for three clues in each eye:

• The eye jerks or bounces as it follows the light, instead of gliding smoothly
• Distinct jerking that lasts when the eye is held at the far side for at least four seconds
• Jerking that starts before the eye has turned 45 degrees

In NHTSA’s original research, four or more of the six clues sorted people correctly at a 0.10 blood alcohol level about 77 percent of the time. In a 1998 San Diego field study of 297 drivers, officers using all three tests made the right call about 0.08 in 91 percent of cases.

Two limits matter. The curriculum notes that HGN can also come from certain other drugs and, rarely, from brain injury, tumors, or inner-ear disease. And it is a trained officer’s procedure, not a test to try on a partner at the kitchen table. Bloodshot eyes are on the same curriculum’s list of things officers note at the car window: a cue to look further, not proof.

Is “whiskey nose” caused by drinking?

Not in the way the name suggests. The swollen, bumpy red nose people call whiskey nose, gin blossom, or alcoholic nose is rhinophyma, a form of rosacea, and people who never drink can get it. The American Academy of Dermatology describes it as thickened skin on the nose that can develop when rosacea goes untreated for years, more often in men. Its page on drinking is blunt: people who never drink alcohol can develop rosacea, and rosacea does not mean the person has a drinking problem.

The research is mixed on the details. A 2004 Scottish study titled “Rhinophyma: dispelling the myths” compared 45 patients with rhinophyma against 48 men having eyelid surgery and found no link with how much they drank. A study of more than 82,000 U.S. nurses did find that women who drank more had a higher risk of developing rosacea. Either way, a red nose is not evidence of a drinking problem, and treatment is a dermatologist’s job.

Other physical signs of drinking: the flush and the liver

Face turns red after one or two drinks

About a third of people of East Asian descent get a fast, bright flush, often with nausea and a racing heart, after a small amount of alcohol. It is mostly due to an inherited shortfall in an enzyme called ALDH2, which clears acetaldehyde, a toxic breakdown product of alcohol. NIAAA researchers have linked this flushing response to a much higher risk of esophageal cancer in people who drink. So the flush is not a sign of a drinking problem. In people with the ALDH2 shortfall, it is a sign that drinking costs them more. Rosacea, heat, spicy food, and some medicines can also redden the face, per MedlinePlus.

Yellow eyes, spider veins, red palms

These are liver signs. According to MedlinePlus, alcoholic liver disease may cause no symptoms at all, or symptoms that come on slowly. Small, red, spider-like blood vessels on the skin can appear early. Yellowing of the skin or the whites of the eyes (jaundice), red palms, easy bruising, and confusion come later. Other conditions cause them too. Anyone with yellow eyes should see a doctor promptly, whatever the reason, and someone who drinks heavily should say so at that visit.

Can alcohol make you hallucinate?

Yes. The well-described cases come mostly from withdrawal, after a heavy, daily drinker stops.

MedlinePlus says withdrawal symptoms usually begin within 8 hours of the last drink, though they can start days later, and tend to peak at 24 to 72 hours. Its severe form, delirium tremens, brings sudden severe confusion, agitation, fever, seizures, and seeing or feeling things that are not there. A separate condition, alcoholic hallucinosis, is a psychotic state dominated by hearing voices, and it classically develops as part of alcohol withdrawal too.

MedlinePlus says to call 911 or go to the emergency room for hallucinations, seizures, fever, severe confusion, or an irregular heartbeat. Our alcohol withdrawal timeline lays out when each risk tends to appear.

Eye movement problems with confusion: Wernicke’s

This one is easy to mistake for being drunk. Wernicke’s encephalopathy is a brain emergency caused by a lack of thiamine (vitamin B1), long linked to heavy drinking. Its signs include unsteady walking, confusion, and jerking eyes and other eye movement problems. It is often missed, and prompt treatment can prevent permanent disability. Someone who drinks heavily and is confused and unsteady with abnormal eye movements needs an emergency department tonight.

Can a breathalyzer give a false positive?

Yes, in a few narrow situations. Each one produces a reading where there is little or no alcohol in the blood. None of them lowers the blood alcohol of someone who has actually been drinking.

• Mouthwash and mouth alcohol. In a 2020 Swedish study, rinsing for 30 seconds with a mouthwash containing 22 percent alcohol kept breath readings above Sweden’s strict legal driving limit for 11 minutes on average and up to 15, with almost no alcohol reaching the blood. In a Canadian study, 30 people who had not been drinking rinsed with diluted gin and spat it out; their breath readings averaged 0.091 five minutes later and 0.014 at ten minutes. The effect lives in the mouth, and it fades over minutes.
• Ketoacidosis. This state, which can come with poorly controlled blood sugar, floods the blood with acetone, and the body converts some of it to isopropanol. In one case report, a driver with ketoacidosis and no alcohol in his blood tested positive on a handheld screening device; the evidential breath instrument then detected an interfering substance in his breath.

In its 2008 ruling on the Alcotest breath instrument, State v. Chun, the New Jersey Supreme Court described a 20-minute wait, with the operator watching the person, before a breath sample is taken, so that alcohol left in the mouth does not inflate the reading.

For a family wondering whether someone is drinking, the breathalyzer question is a side road. The pattern tells you more.

What is hangxiety?

Hangxiety is slang for the anxiety and dread that can come with a hangover. NIAAA lists anxiety and irritability among typical hangover symptoms. Hangovers are worst as blood alcohol falls to about zero and can last 24 hours or longer. There is no proven cure other than time, and NIAAA says a morning drink, the “hair of the dog,” can prolong the misery.

The word comes with a little research behind it. In a 2019 study of 97 social drinkers tested at home, highly shy people were marginally less anxious while drinking, a borderline result, and significantly more anxious the next morning. In those shy drinkers, the bigger the morning-after jump in anxiety, the higher their score on the AUDIT, a standard screen for alcohol use disorder.

The line to watch is between a bad morning and withdrawal. MedlinePlus lists anxiety, shakiness, sweating, a racing heart, and poor sleep among alcohol withdrawal symptoms. Anxiety and shakes that a drink fixes can point past a hangover, toward physical dependence: the body has started to need alcohol to feel normal.

Physical signs are a reason to talk, not a diagnosis

Red eyes and a rough morning describe a night. An alcohol use disorder is a pattern: drinking more than intended, failing to cut down, needing more to feel it, withdrawal as it wears off. No eye, nose, or breath reading measures that.

Short questionnaires get much closer.

• The AUDIT. A 10-question screen developed by the World Health Organization for primary care. Its first three questions, on how often and how much, are used on their own as the AUDIT-C, per NIAAA.
• NIAAA’s single question. “How many times in the past year have you had (4 for women, or 5 for men) or more drinks in a day?” NIAAA says an answer of one or more warrants follow-up.
• NIAAA’s symptom checklist. Eleven past-year questions on Rethinking Drinking. Two or three yeses suggest a mild alcohol use disorder, four or five moderate, six or more severe.

These are screens, not diagnoses. But they move the conversation off “your eyes are red” and onto something the person can check for themselves.

If you are worried about someone, pick a time when they are sober and you are calm. Say what you have seen over weeks, not one night. Ask, then listen longer than feels natural. You are not trying to win the first conversation; you are trying to make sure there is a second one.

When the signs point to detox

A few signs are about the body’s dependence on alcohol: shakes, sweating, anxiety, or a racing heart within hours of the last drink, a morning drink to steady the hands, hallucinations after stopping. Those change the question from cutting back to stopping safely.

For a daily drinker, stopping suddenly is not the safe default. Stopping with a clinician watching is. Alcohol withdrawal can progress to seizures and delirium tremens. Our alcohol detox guide covers hospital, inpatient, and outpatient detox in New Jersey, and can you detox from alcohol at home covers when home is and is not an option. When you call a program, ask how it watches for Wernicke’s and whether thiamine is part of its standard alcohol protocol.
