The correct answer is
Boric acid
Acid Constituent of Eyewash
Boric acid is the acid constituent of eyewash solutions. It is chosen for its safety and efficacy in eye care.
- Mildness: Boric acid is a mild antiseptic and astringent, suitable for sensitive eye tissue.
- Safety: It helps cleanse the eye and relieve minor irritation without causing significant harm.
- pH Balance: It maintains a slightly acidic pH, similar to natural tears.
Stronger acids like Sulphuric acid (H2SO4), Hydrochloric acid (HCl), and Acetic acid are too corrosive or irritating for safe use in eyewash.
