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: My doctor says I have a cataract, but he wants to wait a while before removing it. Why?
A: A cataract usually starts very small and practically unnoticeable, but grows gradually larger and cloudier. Your doctor is probably waiting until the cataract interferes significantly with your vision and your lifestyle. You need to continue to visit your eye doctor regularly so the cataract's progress can be monitored. Some cataracts never really reach the stage where they should be removed. If cataracts are interfering with your vision to the point where it is unsafe to drive, or doing everyday tasks is difficult, then it's time to discuss surgery with your eye doctor.
Q: Why does allergy season affect my eyes?
A: It’s that time of the year for allergies, and for those who suffer, it’s more than just sneezing. It can mean months of itchy, watery, and puffy eyes. Because many of the allergens are in the air, they easily get into the eyes and cause problems. For some people, a sudden case of red and watery eyes can feel like an infection when really, it’s just allergies. Eye allergies, known as “allergic conjunctivitis”, can often be treated with over the counter medication, but for some, it is not enough. Let us help you manage your allergies this season.
