In the magazine Very Well HealthDr. Ashley Brissettes, an ophthalmologist and cataract surgeon in New York, warns about lenses sold without a prescription. Many lack sterility and adequate fit, promoting serious infections like keratitis, an inflammation of the cornea caused by bacteria or fungus. The risks are multiple: corneal abrasions, loss of vision or even allergic reactions. “Certain materials or dyes in these lenses may trigger allergic reactions, causing discomfort and inflammation“, she explains.
Non-prescription lenses: an underestimated risk
Even for a short period of time, wearing colored lenses increases the risk of infection. And this danger does not only concern unregulated models. Dr. Miel Sundararajan, an ophthalmologist in Washington, points out that poor hygiene practices – sleeping, bathing or showering with your lenses, not washing your hands, or reusing a solution – can cause abrasions or severe infections, including with prescribed lenses.
How to wear colored lenses safely
If you still decide to adopt a demon look for Halloween, certain precautions are necessary:
- Consult an eye care professional before any purchase for a suitable fit;
- Clean and preserve your lenses with a dedicated solution, never with water or saliva;
- Change your case regularly and respect the recommended wearing time;
- Buy only from opticians, pharmacies or certified sites.
When to consult an ophthalmologist urgently
Persistent redness, intensifying pain, blurred vision or increased sensitivity to light should alert you. In case of discomfort after removing the lenses, if the symptoms do not improve within 24 hours, you should consult a specialist quickly.
