A contact lens is an optical device that, placed on the surface of the eye, compensates for a visual anomaly.
Lenses correct the vast majority of visual defects, myopia, hyperopia, astigmatism and presbyopia.
Lenses require strict rules of hygiene.
Any deteriorated lens should be discarded immediately.
Only lenses prescribed for prolonged use can be worn day and night, but prolonged wearing increases significantly the infectious risks, which can lead to ocular complications.
Never sleep with daily lenses that do not allow sufficient oxygenation of the eye when the eyelids are closed, except for a few minutes’ nap.
Once a year, have your eyes checked by your ophthalmologist.
When you remove them, place your contact lenses in areas that are not too dense and especially dusty.
Smoke is harmful to contact lenses.
Generally, lenses can be worn for up to 14 hours a day. Beyond this period, the quality and effectiveness of the lenses decreases due to the deposits of impurities that accumulate between the cornea and the lens. Abnormal eye strain may also result.
In case of irritation, do not rub the lens and do not touch it with your fingers except to remove it.
Any manipulation of the lenses must be preceded by a careful washing of the hands.
Do not lend your lenses! These are strictly personal accessories. Any possible infection of the eye can be transmitted through the lenses.
The frequency of renewal of the lenses is indicated on the prescription. Consider it rigorously.
Never exceed the shelf-life, let alone the expiration date of the lenses. The first depends on the opening date of the container, while the second, determined by the manufacturer, is mentioned on the package.
