There are lots of sayings, myths and misconceptions about eyes and eyesight. We’re here to help sort fact from fiction in some of the most common ones:
Fiction. It is more difficult to see in the dark or in dim light than in brighter light, so you may get a headache if you read in the dark, but you will not cause yourself any harm.
Fiction. The membrane that covers the white of your eye (the conjunctiva) also lines your eyelids, so it is impossible for a contact lens to get lost behind your eyes.
Fiction. Although you may not be able to see very well with them and may get a headache or double vision, you won’t come to any harm from wearing glasses that are not your prescription. However, you should only ever wear glasses that are your prescription when you drive.
Fiction: Watching too much TV or sitting very close to it may make your eyes tired or give you a headache – particularly if you are watching TV in the dark – but won’t cause any permanent damage.
Fiction: People normally need glasses because of the shape and size of their eye. Exercises won’t help this.
Fiction: There is no scientific proof for this. However, when optometrists carry out eye examinations they not only test your sight, but also check the health of your eyes and look for signs of some general health problems.
Fiction: The health of your eyes has nothing to do with the number of hours you use them.
Fiction: How your child holds a book has no effect on the health of their eyes and doesn’t necessarily mean they need glasses. Sometimes children find it more comfortable to read close-up and their very good focusing ability makes it easy for them to do so. However, your child sits too close to the television, it may mean that they have difficulty seeing further away. Take them to an optometrist.
Some fact. Carrots are a source of vitamin A, which is important for the eyes – and should be part of a well–balanced diet that supports your all-round health. Poor nutrition has been implicated in diseases such as age-related macular degeneration (AMD).
