Meth Eyes: Does Meth Dilate Or Constrict Your Pupils?
Meth use dilates the eyes from the rush of dopamine felt in the central nervous system. Methamphetamine can also cause rapid eye movement, impaired vision, and other long-term eye issues.
Side effects of meth can manifest mentally and physically. The rush of dopamine dilates the eyes, and after a long period, meth addiction causes other ocular effects.
Meth abuse creates pleasurable feelings, such as mental alertness and euphoria, but it also induces a slew of dangerous short and long-term effects.
Below we’ll explore some of the effects of meth on the eyes and how it can damage other parts of the body.
Effects Of Meth On The Eyes
Many substances cause retinal damage, but methamphetamine creates several short-term effects on the eyes upon ingestion.
No matter how meth is abused, it can cause eye damage. However, snorting meth puts it close to the eyes, so its effects can be increased.
Rapid Eye Movement (REM)
Crystal meth and other forms of meth can cause rapid eye movement (REM).
With REM, the eyes move back and forth in rapid succession. This creates mental effects such as confusion and an inability to concentrate.
Dilation of the pupils occurs after smoking meth. Pupils may appear larger than usual when a person is engaging in methamphetamine abuse.
One of meth’s effects is a rise of dopamine in the body and brain, which causes the dilation of pupils.
Vision impairment and vision loss are other effects that methamphetamine drug use has on the eyes.
Abusing methamphetamine can lead to blurred vision and may impair eyesight to the point of temporary blindness.
Long-Term Effect Of Meth On The Eyes
Meth can have long-lasting effects on the eyes that may not go away, even when drug abuse stops. This can lead to many health care complications.
Some long-term effects of meth on the eyes are:
- constricted blood vessels
- corneal ulcers
- crystalline retinopathy
- retinal vascular occlusive disease (arteries to the eyes constrict, stopping normal blood flow, forming blood clots)
