Are photochromatic spectacles bad for your eyes?

I wear glasses and have always wished that i could get sun-glasses whenever im out in the sun(for sporting events such as golf). Anyway, i can't buy sunglasses (because i already wear spectacles) so im thinking of getting some photochromatic glasses.
My buddy told me that these are actually harmful to your eyes especially if you work with computers often.. is this true??

Photochromatic lenses are not bad for your eyes - at all. Most people really like them because it allows them to wear only one pair of glasses indoors and out. I own a pair of Transtions lenses and they don't get dark enough in the car for me. They are activated with exposure to UV rays from the sun and in the car, they use a protective coating on the windows to keep those UV rays out. So they really aren't a substitute for a nice dark pair of polarized or regular dark sunglasses, so you may want to pick up a pair of shades for driving anyway. But outside, especially on sunny, chilly days they get really dark. And they lighten up almost 100% inside. Photogray lenses, which were the first photochromatic lenses get much darker in in the car because they are sensitive to the light, not the UV. So they darken any place that's bright, including indoors and for that reason, a lot of people didn't like them. They didn't like looking like they were wearing tinted lenses all the time. They are also about 4x's heavier than plastic so for those with moderate to heavy prescriptions, their glasses weighed a ton. Transitions lenses are available in plastic, hi-index plastic, and polycarbonate.

I don't know where your friend would have gotten his information from. Most people are bothered by the glare that the computer screen casts on their lenses and there is a coating called an anti-reflective coating that you have put on your lenses to significantly cut down on that. The glare produces a lot of eye strain and fatigue, especially for those who are on the computer 8 hrs. a day. Its also good for nighttime driving. The glare coating works really well with the Transitions. They tint to protect you from the sun, and then the coating will give you protection from glare, which is something regular sunglasses don't do.

So, good luck. I hope this clears that up for ya! Talk to the optician at your optometrist's office and have them hook ya up with a pair. And ask for either Crizal or Zeiss anti-reflective coating on them too! You'll be SO glad you did!!!
