All protocols

Avoid caffeine on the day of MDMA use, and ideally the day before and day after as well, because caffeine may increase MDMA neurotoxicity.

Avoid taking MDMA together with other stimulants, including cocaine, due to increased toxicity risk from compound interactions.

Maintain adequate fluid and electrolyte intake during MDMA exposure, especially in hot environments or when temperature regulation is poor, to help regulate body temperature and reduce neurotoxicity risk.

Keep the environment temperature-controlled during MDMA use and avoid hot, high-movement settings such as rave or dance environments, outdoor heat, or situations where body temperature rises, because elevated temperature can contribute to neurotoxicity.

Common post-MDMA crash supplement protocols using serotonin or dopamine precursors and magnesium are not evidence-based. 5-HTP, L-tryptophan, L-tyrosine, and magnesium may not aid recovery and could be detrimental.

For trauma or PTSD, use quality talk therapy that includes a strong patient-therapist rapport, a supportive and safe space to explore trauma and current life, and insight into why you feel the way you do within a broader context that brings some relief.

Every baby should receive an eye exam in the first few days after birth focused on checking for a normal red reflex to screen for serious eye disease.

Trigger an eye exam in babies or toddlers if parents notice lack of eye contact, failure to look toward sounds, nystagmus, or other concerning visual behaviors.

Children should undergo amblyopia screening around elementary school age, often through school screening programs, to detect strabismus or unequal refractive errors.

Even if amblyopia or misalignment is detected later in childhood or early teen years, it is still worth trying to retrain the weaker eye and realign the muscles.

Use eye protection during debris-risk work such as metal grinding, gardening, sanding, sawing, woodshop work, and similar activities; regular glasses may help, goggles are better, and safety goggles are recommended for higher-risk tasks.

For blepharitis or buildup around eyelashes, do eye scrubs to lightly clean the eyelashes; with eyes gently closed, lightly scrub the lashes, often using diluted baby shampoo, without scrunching the eyes tightly or scrubbing abrasively.

Use commercially available eyelid cleaning pads to lightly clean the eyelashes.

Use over-the-counter sterile saline solution to rinse the eye if something is in it; do not use seawater or pool saltwater.

Use artificial tears to rinse the eye or relieve dry eye. Preserved and non-preserved versions are safe for eye use; for most dry eye, regular over-the-counter drops are sufficient, but if using more than a couple drops regularly, switch to preservative-free single-use vials because preservatives can irritate and inflame the ocular surface.

If you feel dirt or an eyelash in the eye, hold the lid open and rinse with artificial tears, wetting drops, or saline drops.

Use reading glasses for presbyopia rather than delaying correction; examples given include +1.5 readers now and +2.0 readers in a few years.

Use the corrective lenses that provide the sharpest vision rather than intentionally undercorrecting to 'exercise' the eyes.

For certain external eye muscle alignment issues, especially in children or young adults, clinicians may intentionally undercorrect or avoid full prism correction to force exercise of eye alignment.

In some children, a small plus lens may be used to reduce the effort of turning the eyes inward during near work.

Use pencil pushups for convergence insufficiency or as a visual exercise; focus on a pencil from arm's length and slowly bring it toward the nose, then back out, for about 10 to 25 repetitions once or twice a day a few times a week; not harmful.

Special athletic training goggles that intermittently black out vision can be used to train performance under reduced visual information; examples given include blacking out vision for one-thirtieth, two-thirtieths, or three-thirtieths of every second.

Contact lenses can provide higher quality vision than glasses for some people by correcting higher-order aberrations, but they alter tear dynamics and oxygen diffusion and may become less tolerable with age. Prefer daily disposable contacts over two-week or four-week lenses because they are safer and avoid cleaning-related infection risk, despite higher cost.

Be very attentive to recommended contact lens cleaning and use protocols to reduce risk of bacterial or fungal corneal infection, and do not sleep in contact lenses overnight because closed eyelids reduce oxygen to the eye surface and increase infection risk.

Use eyeglass lenses that block UV light; guest states UV blocking is standard in eyeglasses and beneficial for protecting eyes from cataract formation and other UV-related damage.

Photochromic glasses that darken in UV light can be used outdoors; they react specifically to UV wavelengths.

If you already have dry eye, LASIK may not be a good idea because it can worsen dryness by affecting corneal nerves.

LASIK reshapes the cornea to correct refractive errors and can sometimes produce better-than-20/20 vision; best considered after prescription has been stable for years and generally avoided in people with significant dry eye.

Wait to do LASIK until the eyeglass prescription has been stable for two to five years, typically into the 20s rather than childhood or early teens.

Preservative-free artificial tears can be used as often as needed, even every hour, without harming the eye.
