Health Tips
Please use any lubricating eye drops only when u feel the necessity, like if u are having the symptoms of eye dryness or itchy or sore eyes. Don't use any eye drops as a daily routine unnecessarily , as most of them come with preservatives for long term storage, which are a threat to eye surface on long term use.
