The best news about eyes & Birmingham
Fact: Excimer lasers are "cold" lasers, and do not burn eyes. The smell that occurs during treatment is corneal tissue being precisely vaporised as the cornea is reshaped. Nothing burns. In fact the laser is so cool that it can make shapes on matchstick heads without settting them alight!
Until recently, everything we could "see" was seen using light or radiation waves.But now researchers, including the University of Birmingham Gravitational Wave Research group, working on the LIGO experiment have detected a signal from a binary black hole. This exciting discovery is the culmination of over 40 years of work by an international collaboration of thousands of scientists and engineers at the Advanced LIGO experiment, one of the most precise instruments to have been designed and built. The successful operation of Advanced LIGO is one of the greatest achievements of experimental science – and Birmingham played a key role. Now we will be able to "see" or get images of the universe using gravitational waves.

Myth #5: Vision correction surgery is 100% safe. This is not true.
Fact: Every operation has risks. Laser or lens surgery may affect your vision so that neither glasses nor contact lenses can sharpen vision back to your pre-surgery vision. So choose an experienced surgeon who will explain the risks to you personally and keep them to a minimum. Many people want vision correction surgery but very few need it. So carefully consider the risks and benefits.
Myth #4: Laser eye surgery is not safe
Fact: Over 50 million people have are enjoying the life changing benefits of laser eye surgery. Would they have had it if it wasn’t safe? Click here for more information about the incredible technology used to make it safe.

And the humble sprout is also a low glycaemic vegetable useful for losing weight and a source of other important vitamins and trace elements that keep us healthy. Di-indolyl-methane boosts our immune systems, sinigrin protects against colon cancers, Vitamin A keeps our skins and eyes healthy and protects against lung and mouth cancers. Vitamin K slows down Alzheimer's, Potassium controls heart rate and blood pressure and iron builds blood cells.
So, take a fresh look at those humble sprouts at Christmas dinner this year. Sprouts aren't sweet but this BBC ad is!
Myopia is the most common eye disorder with 40% of Europeans and over 90% of Koreans and Japanese having to wear glasses and contact lenses to correct the disorder. The rapid increase in the numbers is caused by a number of factors including spending more time indoors (see "the myopia epidemic").
Myopia is caused by the eye growing too long. The focus can be be corrected with laser eye surgery and lens surgery, but diseases linked to the elongated eye such as retinal detachment, macular degeneration, cataracts and glaucoma are still more common. So preventing or slowing down the elongation of the eye is important for the future eye health of today's children.
Encouraging children to play outdoors has been known to help. But a recent study of 400 children has shown that a low dose of a well known eye drop called "Atropine" can slow the progression in some children too. So hopefully this epidemic of myopia can be stopped and even reversed.

About half of the UK population naturally have blue eyes and they are more common in Scotland and Northern Ireland. But can darker eyes be safely changed to blue?
Artificial iris implants are donut shaped, blue, silicone discs placed in front of the natural iris. But over 80% of eyes developed blurred vision from damage to the lens or cornea (clear window on the surface of the eye) requiring removal of the implant and further surgery (see the scientific article reference). And they cause high pressure and glaucoma which can irreparably damage sight.
A new laser treatment developed by Strōma Medical releases melanin pigment from the iris (see Eye colour facts #1), making the iris a lighter colour (see Eye colour facts #3). But how long will the treatment last before new pigment is produced? And will the released pigment cause pressure damage to the eye? The safety of the treatment is being investigated.
Albinos are animals and people with pale skin, eyes, hair, fur, or feathers because they can't make melanin normally (see Eye Colour Facts #1). There are many types of albinism. Most albinos have blue eyes, but some are pink because the iris (the colored part of the eye) has so little color that the blood vessels inside the eye are visible through the pale, white iris.
Besides giving skin, eyes, and hair its color, melanin protects eyes from the sun and albinos are very sensitive to light. But albinism may be linked to other eye abnormalities such as abnormal nerve connections and light receptors, constantly moving eyes, squints, short sightedness and poor vision even with glasses or laser eye surgery.
