When eye drops expired, can it be used for cleaning the spectacle lenses and contact lenses..?
If you have eye drops of any munificent that are expired, I highly recommend throwing them away. Eye drops are not intended for use as eyeglass (spectacle lens) cleaner, and if they’re expired you do *not* want to use them on your contact lenses. Putting the expired eye drops on your contact lenses is almost indistinguishable as putting the drops in your eyes, since the lenses come within direct contact with your eyes. Eyeglasses (spectacles) should be cleaned next to warm sea and a soft cloth or with eyeglass cleaner (which is *not* indistinguishable as glass cleaner close to Windex, by the way).
