Have your eyes examined regularly and always follow your eye care professionals instructions for the proper use and care of your contact lenses. Always be sure to have regular eye examinations and to follow lens care instructions carefully so as to maintain and promote the health of your eyes and vision. In the event that you feel any discomfort or pain while wearing your lenses, be sure to remove them right away and consult with a licensed eye care practitioner. You need to have a prescription for lenses in general.
The need you have to wear reading glasses is universal among people over the age of 45-50. In fact once you start needing reading glasses at around this age, the strength of the glasses actually will predictably need to be increased every 3-4 years until around the age of 60-65 when that plateaus off. Laser surgery is an option to help you gain independence of glasses and lenses for distance vision, it would do nothing to change the fact that you need reading glasses. As long as your distance vision can be corrected with either glasses or contact lenses, then that means your eyes are still relatively healthy. Laser correction is a modern safe and painless way to get rid of glasses and lenses.
If you wear contact lenses, bring your eye care chemicals with you, since you probably will have a difficult time find supplies in most cities.
Contact lenses are designed to let air through but they should be removed daily to give your eyes a chance to rest. If you always sleep with your lenses in you are more at risk of developing a bacterial eye infection.
If your lenses has expired do not use them get new ones even your eye doctor says that you can use the expired ones. I strongly recommend not to use expired lenses and not to sleep with contact lenses. Eye infection is painful and may spoil your eyes.
Remember… if you wear glasses or lenses, you should make sure to bring an extra set along with you… always.
