Nerve damage in the eye (optic neuropathy)Ĭhoroidopathy and optic neuropathy can lead to impaired vision or vision loss.Fluid buildup under the retina (choroidopathy).Drinking too much coffee one day may not lead to long-term eye damage, but drinking an excessive amount of caffeine every day is more likely to cause problems. These are most likely to occur with sustained high blood pressure. High blood pressure can have many negative effects on your eye health. Address the potential culprits one at a time to determine the cause of your eye spasms and relieve this discomfort. Allergies and dry eyes can cause twitching and irritation as well. If you’re suffering from twitching eyes, you may also want to consider your alcohol intake, sleep schedule, and stress levels. Some people ask, “Can coffee make you see spots?” While spots themselves shouldn’t appear, the other disruptive visual effects of caffeine can create a similar disruption and frustration.Ĭaffeine isn’t the only thing that can cause myokymia, though.

In many cases, individuals don’t realize that they have this condition until irreparable eye damage has already occurred. There are many forms of glaucoma, but it is often caused by abnormally high pressure in the eye, which damages the optic nerve. Therefore, excessive caffeine intake may increase the likelihood of developing glaucoma for some patients. Elevated IOP is a major risk factor for glaucoma. However, the risk of glaucoma does not increase for those with a lower genetic risk score.Ĭaffeine intake is associated with an increase in intraocular eye pressure (IOP). Among individuals with the highest genetic risk score for elevated eye pressure, the risk of glaucoma may increase more than three-fold in association with high caffeine consumption. However, this was only present in those with a high genetic predisposition for the disease. Research led by the Icahn School of Medicine at Mount Sinai demonstrated a connection between daily caffeine consumption and the risk for glaucoma. “ Coffee.” used with permission via Unsplash by Jason Yoder Understanding the connection between coffee and eyesight can help you make informed decisions about your health.
