Dry eyes contact lenses:Your Eyes are specialGive them the right protection
Eyes that do not produce the required amount of tears are called dry eyes. This is a disease caused when the tear production is decreased or when there is an increase in the tear film evaporation. There is an irritation caused due to this, the eyes have a burning and a dry sensation. These symptoms occur mainly when there is loss of water in the tears, which cause the tears to become more salty or hyper tonic. This disease mainly occurs with older people because tear production decreases, as
a person gets old.

There are various conditions that cause dryness, smoky and heaty room, hair dryers, exposure to wind; riding a bike also can cause the lenses to dry
Treatment:
People who experience the dry eye syndrome do not have a permanent cure but lenses and other medication like drops or ointment can reduce it. Usually these patients cannot tolerate lenses but a great amount of improvement has been done in the technology. They are now fitted with newest polymers; this allows the lenses to retain water. This helps the person not feel the dryness. Restasis is a drop that allows these patients to wear the contact lenses for as long as eight hours. These are the only drops approved by the FDAto treat chronic eyes. Earlier people had no choice but to wear glasses, now they have to be thankful to the latest technology in contact lenses and also the multifocal lenses.
Types:
