Q: What is blue light and why is it dangerous?
A: Blue light is part of visible light and has a wavelength close to UV rays on the light spectrum. It is naturally produced by the sun, given off by fluorescent light bulbs, and emitted by LED screens on computer monitors, tablets, and smartphones. The eye's natural filters do not block blue light and chronic exposure may increase your risk for age-related macular degeneration. Evidence also shows that blue light exposure can lead to sleep problems.
Q: Why do I have difficulty with my bifocal glasses while working on my computer?
A: Many people experience discomfort if they use a desktop computer while wearing bifocals because, to see the monitor at eye level, they look through the top of their eyeglasses, which is the portion for distance vision. To compensate, some patients have to tilt their head upwards to bring the computer into focus on the lower near-vision portion of the lens. However, that's not ideal either, since computer monitors are usually positioned farter away than typical near-vision activities and reading material. One solution for this is to have a separate pair of bifocal computer prescription lenses. In this case, the top part of the glasses has the appropriate power for the monitor at whatever specific distance it is from the eye; the bottom portion of the glasses is the traditional bifocal power for regular near viewing. Also, anti-reflective coatings help reduce eye fatigue and glare from prolonged computer use.
Q: What are the pros of daily disposable contact lenses?
A: Daily disposable contact lenses are great for many reasons. The risk of infection is reduced, because a new sterile lens is used everyday, and there is no need to clean the lens or the case. This is also a great option for patients who have allergies, contact lens solution sensitivities, or dry eye, as it eliminates the buildup of contaminants on the lenses, which can exacerbate those problems. Dailies make for a low-maintenance and comfortable option for almost any patient!
Q: My eye is suddenly red and irritated/painful, what should I do?
A: Whenever you get a red eye, it is very important to make an emergency eye appointment immediately with our eye doctor to see what the cause is. Some red eyes will go away with rest, but some are vision threatening and could cause blindness within 24 hours (ie. If the cause was a microorganism from contact lens wear). If you wear contact lenses, remove them immediately and do not wear until the redness subsides. Our doctor uses a high magnification slit lamp to examine your eyes to determine the exact cause of the problem and will treat accordingly. A family doctor usually does not have the necessary equipment and will treat based on your symptoms only. If your eyes need antibiotic eye drops, our eye doctor can prescribe the proper ones for your condition.
Q: How do I know if I have Dry Eye?
A: Dry eye can cause quite a few symptoms, anything from the eyes actually feeling dry to the eyes watering often, or having a burning, itchy, or irritated feeling. One of the most common symptoms is the eyes feeling gritty or like something is in your eye. Most people will often experience blurred vision since the tears, which comprise the outermost surface of the eye, are unstable.
