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 smart phone or tablet in the dark damage my eyes?
A: Reading from a tablet or smart phone in the dark is okay for your eyes, as long as this is not for a long period of time. There is good lighting from these devices, with good contrast. There is, however, blue light emitted from these devices. Blue light is a short wavelength light, with high energy that may cause damage to the structures of the eye if exposed for a long period of time. As well, studies have shown this blue light can disrupt melatonin production which is required for a healthy sleep cycle. Doctors of Optometry recommend limiting screen use 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!
