Fact: Eye exercises will not improve or preserve vision or reduce the need for glasses. Your vision depends on many factors, including the shape of your eyeball and the health of the eye tissues, neither of which can be significantly altered with eye exercises.
As the eyes age, problems with vision become more common. Learn how to recognize the risk factors and symptoms of specific eye diseases — cataract, glaucoma, age-related macular degeneration, and diabetic retinopathy — and what steps one can take to prevent or treat them before your vision deteriorates.
Myth: Reading in dim light will worsen our vision.
Fact: Dim lighting will not damage our eyesight. However, it will tire our eyes out more quickly. The best way to position a reading light is to have it shine directly onto the page, not over the shoulder. A desk lamp with an opaque shade pointing directly at the reading material is ideal.
Myth: Carrots are the best food for the eyes.
Fact: Carrots, which contain vitamin A, are indeed good for the eyes. But fresh fruits and dark green leafy vegetables, which contain more antioxidant vitamins such as C and E, are even better. Antioxidants may even help protect the eyes against cataracts and age-related macular degeneration. Just don’t expect them to prevent or correct basic vision problems such as nearsightedness or farsightedness.
Myth: It’s best not to wear glasses or contact lenses all the time. Taking a break from them allows our eyes to rest.
Fact: If we need glasses or contacts for distance vision or reading, we should use them. Not wearing glasses will strain our eyes and tire them out instead of resting them. However, it will not worsen our vision or lead to eye disease.
Myth: Staring at a computer screen all day is bad for the eyes.
Fact: Using a computer does not damage our eyes. However, staring at a computer screen all day can contribute to eyestrain or tired eyes. People who stare at a computer screen for long periods tend not to blink as often as usual, which can cause the eyes to feel dry and uncomfortable. To help prevent eyestrain, we should adjust the lighting so it doesn’t create a glare or harsh reflection on the screen, it is advised to rest the eyes briefly every 20 minutes, and make a conscious effort to blink regularly so that our eyes stay well lubricated.
It’s important to know what to do not only when disease strikes, but what to do before and after. We should know the warning signs and how a diagnosis is made. And the best treatment options for that.
The good news is, with the proper treatment decisions, those eye diseases can be addressed and controlled and their potential to compromise our sight can be halted.
Our eyes do change as we get older. That’s a truth we can do little about. It’s the consequences we can change.
We we should learn all the facts about treating adult eye diseases.
