Eye doctor warns against using eye‑whitening (red‑eye) drops

An optometrist cautions that eye‑whitening or red‑eye drops can mask underlying problems and may cause rebound redness; she recommends preservative‑free lubricating tears as a gentler alternative, and the FDA has recently warned about 26 over‑the‑counter eye drop products.

Many people skip routine eye care and may not notice early signs of eye disease. An optometrist, Dr. Michelle Holmes, highlighted concerns about over‑the‑counter eye‑whitening or red‑eye drops. She said those drops constrict blood vessels and can temporarily hide redness that signals irritation, infection, or other eye conditions. The article also notes recent FDA warnings about a group of over‑the‑counter eye drop products. Key points: - About 40% of Americans considered at high risk for vision loss did not have an eye exam in the past year, according to the Centers for Disease Control and Prevention. - Redness in the front of the eye often reflects dilated blood vessels that can indicate irritation, allergy, infection, corneal abrasion, or other issues. - Red‑eye or eye‑whitening drops work by constricting blood vessels and can mask symptoms, creating a false appearance of improvement. - Those drops can produce a rebound effect, where redness returns worse than before, and some people may become dependent on them; the optometrist noted preservative‑free artificial tears as a gentler product choice and the FDA has issued warnings about 26 OTC eye drop products related to infection risk. Summary: Using redness‑relieving eye drops can conceal signs that help clinicians identify underlying eye conditions and can lead to rebound redness and dependence for some users. Regulators and clinicians have flagged safer product options and specific OTC products of concern, and how the cause of redness is identified will influence subsequent care and testing.
