The use of the Orchid tree (commonly referring to species in the Bauhinia genus, such as Bauhinia variegata or Bauhinia purpurea) for eye problems is primarily rooted in traditional medicine systems, particularly in Ayurveda and some folk practices of South Asia. In these traditions, preparations from the bark, flowers, or leaves have been employed as eye washes or topical applications to treat conditions such as conjunctivitis, redness, or irritation. However, the documentation of such uses is generally anecdotal, found in ethnobotanical surveys, and mentioned in some traditional medicinal texts.

There is little to no robust scientific evidence supporting the efficacy or safety of Bauhinia species or "Orchid tree" extracts for treating eye ailments in humans. Modern pharmacological studies have focused more on their antioxidant, anti-inflammatory, and antidiabetic properties, but not specifically on ophthalmic applications. No clinical trials or systematic reviews currently validate their use for eye problems. Therefore, while the tradition exists, the quality and quantity of evidence is very limited, justifying a low evidence rating.
