Q: What is Amblyopia?
A: Sometimes called Lazy eye, it is the underdevelopment of central vision in one or sometimes both eyes; it also prevents both eyes from working together.
Q: My child passed the screening test at school, isn’t that enough?
A: Distance and reading are two different things. Someone with perfect distance vision can still have focusing problems up close. Doctors need to check for both, many children have undiagnosed accommodative (focusing) problems because no one ever looked for it before. We always check the distance and near vision on all ages because it is so important. Other areas that need to be checked is eye muscle alignment, color vision, depth perception, and overall health of the eyes.
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 many 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.
Q: My previous eye doctor told me I have “stigma!” Am I going to go blind?
A: Stigma is actually referring to a type of refractive error known properly as astigmatism, and no, you will not go blind from having astigmatism; it is not a disease, in fact, it is relatively common. There are three types of refractive error, myopia, hyperopia and astigmatism. The former two are more regularly referred to as nearsighted (cannot see far away) and farsighted (cannot see up close). Astigmatism is simply the third category; it affects both the near and far vision at the same time. Much like nearsightedness or farsightedness, astigmatism is corrected using glasses or contacts. Technically speaking an eye with astigmatism requires two different prescriptions to correct vision in one eye due to the more oval shape of the cornea. This will require a more specialized contact lens and a more in depth fitting procedure. Nonetheless your eye care provider can, and will, correct your astigmatism with glasses and/or contacts.
Q: What are cataracts and how do they affect my vision?
A: A cataract is a gradual clouding of the crystalline lens, located inside the eye, causing decreased vision. Cataracts most commonly occur with aging, and are a normal part of the aging process. Other causes of cataract development include ocular trauma/surgery, radiation, smoking, systemic disease (metabolic and genetic conditions), and certain medications (particularly corticosteroids). Symptoms of cataract vision loss depend on the type, location, and severity of the cataract. Cataracts may cause gradual blurry vision, halos around lights, poor night vision, prescription changes, and glare symptoms. A cataract is treated with outpatient surgery, in which the crystalline lens is removed and replaced with a clear lens implant. Surgery is typically done with local anesthesia, with minimal or no complications. Nearly all patients achieve improved vision and often do not require glasses post surgery. Cataract surgery is one of the safest and most common surgeries performed in the United States. Your optometrist will evaluate your eyes for cataracts at each comprehensive eye exam. Please let your optometrist know if you experience any of the above symptoms.
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: I work all day on my computer. How can I reduce the strain to my eyes?
A: Usually we recommend that the height of the monitor should be level with the tip of your nose. The screen should be 26 - 30 inches away from your eyes. You can prevent glare from the screen and the harmful effects of blue light by wearing anti- glare lenses and Blue light protection . In addition you should follow the 20-20-20 rule; For every 20 minutes of computer use, you should take a break for 20 seconds by looking at an object that is 20 feet away from you. If you feel that your eyes are suffering from computer use, please call to make an appointment so we can evaluate your condition.
Q: Why do I have difficulty with my bifocal glasses while working on my computer?
A: On a desk top computer monitor, many people have difficulty using their bifocals because they are looking through the top or distance portion of their glasses with the monitor being usually at eye level. To compensate, patients often have to tilt their head upwards to bring the bifocal into view and sometimes move closer. Most computer monitors are positioned outward at a greater distance than the everyday reading distances for other activities. One solution for this is to have a separate bifocal computer prescription. 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.
