Can a laser pointer hurt your eyes?

Posterior segment examination a normal fundus in his right eye and small focal yellow opacity in his left eye.

Laser injuries to the eyes are increasingly more common. There are unsafe laser pointers (power output greater than 5mW) in the market bought online.1 The prognosis on recovery can be variable, and in some instances the patient is left with a permanent scotoma. The ABC’s catalyst program has a very informative video on this issue.

Can carrots make you see better?

Can carrots make you see better?

Eating a healthy, well-balanced diet which includes eye health foods will be good for overall wellbeing as well as eye health

Carrots are one of the many sources of Vitamin A which is essential for optimal eye health. Other rich sources of Vitamin A include milk, fish, broccoli, sweet potatoes, pumpkin and dark-green leafy vegetable such as spinach, kale silver beet. A diet deficient in vitamin A can lead to night blindness and other eye problems. But vitamin A deficiency is rare in Australia although pregnant women and those with bowel disease may be at risk.  No amount of carrots will improve your eyesight if you already have a well balanced diet.

Other important nutrients for eye health include; Omega-3 (sources include all fish and shell fish, fish oils containing liver and butter), Zinc (sources include oysters, seafood, nuts and legumes), vitamin E (sources include nuts and whole grains), vitamin C (sources include citrus fruit, berries and tomatoes), and selenium (sources include nuts).

Hope for diabetes sufferers (video)

More than 1.7 million Australians live with diabetes but what many don’t realise is the effect it has on their eyes.  But a new drug is hoping to help sufferers regain vision and hopefully prevent blindness.
