New study finds irreversible structural damage to the eye's corneal endothelium in healthy young adults following Pfizer mRNA injection. The most common symptom of such destruction is Increased sensitivity to light, eveything seems too bright.

Researchers conducted a prospective study on 64 healthy, COVID-naive volunteers. Using advanced imaging tools (Sirius corneal topography and Tomey EM-4000 specular microscopy), they evaluated 128 eyes before vaccination and approximately 75 days after the second Pfizer dose. Researchers suggest that the short term damage might be developing in long term period hence recommend long term research.
