Everyone likes to let their hair down during the Christmas party season, but it can lead to problems for contact lens wearers. Experts warn that poor optical hygiene can lead to serious eye infections and even blindness.
Many people tumble straight into bed after too many drinks, without taking their lenses out first. All too often there are lapses of the usual hygienic treatment of lenses over the party period. The results can be disastrous.
Children will rarely complain about their eyesight but there are some tell-tale signs that all is not well.
Have you noticed that your child sits a bit too close to the television? Has their teacher said they have difficulty reading the blackboard or whiteboard? Do they have a tendency to blink rapidly or are they constantly rubbing their eyes?
Do you need a torch to get to the kitchen for your midnight feast? Do you have difficulty seeing when driving at night? You could be suffering from night blindness.
For most people it takes up to twenty minutes to adjust to seeing properly in the dark. As the surrounding light dims, our pupils dilate (grow larger) to allow them to take in more light to compensate. Dilated pupils present a problem, however, as they alter your ability to focus between near and far objects.
The BBC has reported that a smartphone app has been developed which could bring much-needed eye care to those in need in the remotest parts of the world.
The Portable Eye Examination Kit (Peek) uses the camera of a portable phone to scan an eye’s lens for cataracts.
