While alcohol drinkers experience the effects of "beer goggles", ClinicCompare created an interactive graphic tool explaining how alcohol alters the vision as people drink.
Daily Mail UK reports consuming three units of alcohol can already give a "blurry" effect on women and "slightly blurry" effect on men. This amount is equivalent to two 330ml bottles of 5% beer, three 25ml shots of whisky, or one 250ml glass of red, white or rose wine.
Drinking seven units of alcohol - equivalent to three 25ml shots of vodka or two 175ml glasses of wine can already make women's vision "excessively blurry", although it's not as bad for men.
Alcohol slows down the neurotransmitters responsible for the communication between the eyes and the brain, impairing eye-muscles that cause blurry or double vision.
Although the graphic clearly explains how a person's vision is changed, ClinicCompare explains the level of visual fuzziness would still depend on the person's alcohol tolerance.
As many are aware of the short-term consequences, it is not widely-known, however, how alcohol abuse could lead to long-term eye problems.
"Long term alcohol abuse and short term excessive alcohol use can both lead to permanent loss of vision owing to the direct effect of alcohol on the optic nerves," Alexander Ionides, a consultant ophthalmologist at Clinic Compare told HuffPost UK. "Your eyes are associated with many organs throughout the body, the effect alcohol has on your brain and liver, for example, also has a consequential impact on your eye health.
"To avoid the risk of developing conditions such as toxic amblyopia (a permanent loss of vision and blindness caused by alcohol) always remember to drink occasionally and in moderation."
National Health Security recommends women to drink not more than 2-3 units a day and not more than 3-4 units for men.
