`
`Lumify Vs. Visine: What Is The Difference?
`
`Lumify and Visine eye drops are both available over the counter to relieve red
`eyes. While Visine has been on the market for years, Lumify was just recently
`approved by the FDA in December of 2017. However, the active ingredient in
`Lumify, brimonidine, has been available in prescription products such
`Alphagan-P eye drops for some time. Below, we discuss the similarities and
`differences between Lumify and Visine.
`
`Active Ingredients
`
`The active ingredient in Visine is tetrahydrozoline.
`The active ingredient in Lumify is brimonidine.
`
`
`
`Both tetrahydrozoline and brimonidine are classified as α adrenergic
`2
`agonists. They work to reduce eye redness mainly by causing vasoconstriction
`of the blood vessels in the eye. This creates temporary relief from tissue
`congestion, which is why Visine and Lumify are sometimes classified as ocular
`decongestants. They may also work by lowering the production of
`norepinephrine, which decreases blood flow.
`
`Between tetrahydrozoline (Visine) and brimonidine (Lumify), brimonidine is
`considered a "second generation α adrenergic agonist" and is more selective
`2
`for adrenergic receptors. The clinical significance of this is not well known
`but, brimonidine (Lumify) is thought to have fewer side effects
`than tetrahydrozoline including a lower risk of rebound redness or tolerance,
`also known as tachyphylaxis, a common problem with eye decongestants.
`
`Dosing
`
`The dosing for Visine and Lumify are similar. Both are labeled to be used up
`to four times daily. However, brimonidine (Lumify) is thought to last longer
`per dose than tetrahydrozoline (Visine). Each dose of Lumify should last
`between 6 to 8 hours while each dose of Visine should last between 4 and 6
