Area of Science:

Ophthalmology
Toxicology

Background:

Limited research exists on the ocular effects of tea infusion, particularly in human subjects.
Animal models of cataractogenesis are the primary source of existing literature.

Observation:

A case study investigated the impact of prolonged tea infusion exposure on ocular tissue.
The patient presented with a hypesthetic cornea and secondary limbal stem cell loss.

Findings:

Prolonged tea infusion exposure was associated with corneal keratinization.
Corneal neovascularization was observed as a consequence of the ocular tissue damage.

Implications:

This case highlights potential risks of topical tea infusion use on the human eye.
Further research is warranted to understand the long-term effects and safety of tea infusion on ocular health.
