Soft contact lenses (made of hydrogel or silicone hydrogel) can absorb LSD if it’s in a liquid solution. Soft lenses are designed to absorb and retain moisture, which can include dissolved substances like LSD. This could lead to a slow release of the drug over time as the lens gradually releases the absorbed liquid onto the eye. However, the exact extent of absorption and release would depend on factors like the lens material, the concentration of LSD, and the duration of exposure. I could not find any studies that looked at this as either a complication/hazard, or as a means of delivery therapy.

Eleanor was seriously impacted by her experience, emotionally, psychologically. If you’ve never experienced the LSD ‘high’, it’s not something you want to fall into unwittingly. In this case, even if Eleanor did know about the LSD in the solution she put in her eyes, the protracted impact could and would be more surprising, or even disturbing. That said, LSD has a 1/2-life of 3-5 hours, with all metabolites excreted within 48hours. The effects of LSD wane with each repeated dose, despite the 1/2 life duration. So, even if Eleanor was wearing LSD-soaked contacts, the effect would have been much more pronounced in the first 24 hours, then waning fairly quickly thereafter. I would suspect that the impact would attenuate more quickly if she was wearing her contacts 24/7, rather than removing them overnight. I have no data to indicated how long the LSD dose would remain at significant levels following application and daily wear of the lenses, but clearly if the solution Eleanor was using was in her contact case, she would have been re-dosing at full strength every time she removed the lenses and reapplied them to her eyes, she would have been hit with another full dose – attenuated or not, the effect would still persist for hours.
