Q: What causes myopia?
A: Myopia is caused by a combination of environmental factors and heredity. Studies show that if we can move the focal point in front of the mid peripheral retina we can slow the progression of myopia. The increased use of cell phones and computers, as well as less time outdoors is probably a contributing factor.
Q: Does reading my smartphone or tablet in the dark damage my eyes?
A: Reading from a tablet or smartphone in the dark is okay for your eyes, as long as it's not for a long period of time. These devices have decent lighting and good contrast. However, they give off blue light, and long-term exposure may cause damage to the structures of the eye. As well, studies have shown that blue light at night disrupts melatonin production and interferes with healthy sleep cycles. Optometrists recommend wearing blue light blocking eyewear for extended digital device use, and limiting screen time during the last hour before bedtime.
Q: Can I wear my contact lenses to the beach?
A: Besides the obvious risk of losing them in the water or in the sand, you're are also increasing your risk of contracting a serious eye infection. The ocean water has high levels of bacteria which could contaminate your lenses and in turn cause a bacterial infection in your eyes. We recommend that you take regular eyewear or prescription sunglasses for your day at the beach. Enjoy!
