my grandfather is suffering from arthritis and frequently his eyes turn very dry what can be done to prevent it?

For arthritis here are few tips:

  • Stay active, walk 20 min daily (walk softly)
  • Loose weight if you are over weight.
  • Eat more salmon or other cold water fish.
  • Apply a package of frozen peas or ice wrapped in a towel or cloth if you have swelling especially after any physical activity.

For prevention of dry eyes:

  • Keep the body hydrated.
  • Wear wrap-around glasses when outside.
  • Use humidifiers
  • Avoid outside windy and dry conditions.
  • If you wear contact lenses, take them out for a while. Contacts dry out easily and require lubrication.
