Alcohol and your vision

 The effect of alcohol on your eyes and vision depends on many factors, including how much, how often, and what you drink. It can cause both short-term and long-term visual effects, such as blurred vision, double vision, and dry eye. Even occasional drinking can affect your eyes in some way.

 Short-term effects of alcohol on eyes and eyesight

 Drinking alcohol can change your view in many ways while drinking and immediately after drinking alcohol. For example, researchers found that people who drink alcohol are more likely to find images more appealing, commonly known as the 'beer glasses' effect.

 There are a few other ways alcohol intake can quickly affect your eyes and eyesight: larger pupils and consuming more alcohol than usual.

 Drinking large amounts of alcohol can significantly increase the size of the pupil, although it is temporary, the effect varies from person to person.

 Color blindness and drinking disorders

 Studies have shown that color vision worsens 1-2 hours after drinking alcohol. Color vision can also have long-term effects. According to one study, young adults who drink alcohol may perform worse on color vision tests than those who don't drink at all.

 Diplopia, blurred vision, drinking

 Alcohol intake can cause diplopia (diplopia). Alcoholic diplopia is a temporary effect, but it is only one of the reasons why drunk and drunk driving is so dangerous.

 Blurred vision usually occurs at a blood alcohol level of 0.10%. The number of drinks you need to reach this level depends on your gender, weight, and other factors. For example, a 100-pound woman needs two drinks an hour if her vision is blurred, and a 240-pound man needs five drinks an hour.

 Dry eye and drinking

 A large study examining the effects of alcohol on dry eye found that women were at a significantly greater risk than men of developing dry eye symptoms after drinking alcohol. Drinking alcohol in men did not cause an increase in dry eye symptoms.

 Eye movements and drinking

 According to one study, blood alcohol levels of 0.08% (regulatory restrictions on driving in most states) can affect some eye movements in healthy young adults. The presence of certain types of nystagmus (rhythmic involuntary eye movements) helps police decide whether to arrest a driver for drunk driving. this

 The Horizontal Gaze Nystagmus (HGN) test is one of the three major drinking tests used by police. In the HGN test, police officers ask the driver to remove their glasses and follow the object with their eyes. People who exceed the legal blood alcohol limit are more likely to have:

• Skipping or cramping when following an object such as a finger or flashlight
•  Cramp (shoulder) for more than a few seconds when looking sideways

 The other two main drinking tests used by police are the Walk and Turn (WAT) test and the One. Leg Stand (OLS) test. In these tests, walk straight and stand on one leg.

 Convulsions and drinking

 Seizures may occur in one or both eyes during or after drinking alcohol. There are many causes of eye spasms, but if you develop eye spasms that may be due to alcohol, it may be wise to cut back on drinking for a while.
