Q: How do allergies directly affect the eyes?
A: Chronic allergies may lead to permanent damage to the tissue of your eye and eyelids. If left untreated, it may even cause scarring of the conjunctiva, the membrane covering the inner eyelid that extends to the whites of the eyes. Ocular allergies can make contact lens wear almost impossible and are among the many causes of contact lens drop-out. Most common allergy medications will tend to dry out the eyes, and relying on nasal sprays containing corticosteroids can increase the pressure inside your eyes, causing other complications such as glaucoma.
Q: What are the common symptoms of OCULAR allergies?
A: Excessive tearing, frequent eye rubbing, constant irritation especially in the corners of your eyes closest to the nose, lid swelling or puffy eyes, and red or pink eyes are some of the most common ocular allergy symptoms.
Q: What is meant by the term allergic conjunctivitis? Is that the same as “pink eye”?
A: Allergic conjunctivitis is the clinical term for inflammation of the lining or membrane of the eye, called the conjunctiva, caused by allergic reactions to substances. Although a patient may present with red or pink eyes from excess inflammation, the common term "pink eye" can signify a broad range of conditions and can be misleading, as viruses, bacteria, fungi, and other irritating substances can cause redness resembling a "pink eye." Your eye doctor can differentiate between an allergy and a true infection, which can lead to faster healing with the right treatment.
Q: What exactly is astigmatism?
A: Astigmatism is usually caused by an irregularly shaped cornea, the front surface of the eye. Instead of being a perfect sphere, like a ball bearing or a marble, it can become a little more like a football, being more curved in one direction than the other. This brings light into focus at more than one point on the retina at the back of the eye, resulting in blurry or distorted vision.
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: 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: What are multifocal lens implants?
A: Multifocal lens implants are often used in cataract surgery to reduce the dependency upon glasses for both distance and near vision after the surgery is completed. As with other medical technology, not everyone will be a good candidate for this type of surgical implant. Patients with corneal scarring or significant astigmatism, as well as surgical candidates with eye diseases such as diabetic retinopathy, glaucoma and macular degeneration, may not receive the full benefit from these lenses. Your eye care professional can help determine if this lens implant option is right for you.
Q: What are cataracts and what's the best treatment?
A: Cataracts occur when the natural lens of the eye, positioned just behind the pupil, changes from clear to cloudy. This causes increasingly blurry vision that a higher vision prescription cannot help. When the blurriness worsens to the point that it interferes with a person’s ability to read or drive, or otherwise hinders their lifestyle, the cloudy lens is surgically removed and replaced with a clear plastic one, restoring clear vision. These days, cataract surgery can take as little as 20 minutes, with little down-time and excellent outcomes.
Q: What can I do about Digital Eye Strain?
A: We can help! There are various eyeglass lenses and lens coatings for people of all ages to relieve digital eye strain and ease fatigue after extended reading or computer use. Lens treatments, such as anti-reflective and blue light blocking coatings, protect your eyes and increase comfort. We also prescribe many different types of contact lenses to reduce reading discomfort and make it easier to switch focus from near to far.
Q: Why do my eyes tear up when I am reading or spending time in front of a computer?
A: This may be due to a decreased rate of blinking as you concentrate on reading or working on the computer. When you blink less, less tears are pumped out of the tear drainage system, leading to a welling of the tears. Also, if you have an unstable tear film in conjunction with a decreased rate of blinking, this could lead to reflex tearing. Patients who experience this often have evaporative dry eye, which could be diagnosed with some additional testing.
Q: I have eye allergies, are daily contact lenses better for me than monthlies?
A: The main benefits of daily disposable contact lenses are comfort, convenience and eye health; it's often worthwhile even though they cost a little more. Daily lenses only stay in your eyes for one day, and then get thrown away, eliminating any buildup of bacteria on the lenses that could cause infections or allergic reactions. So for patients who suffer from allergies, dailies are better than monthlies.
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 eyes are always burning and tired, what is causing this and what can I do about it?
A: These are often signs of dry eye syndrome, a very common condition that affects many people over time. Women are generally more prone to developing these symptoms and aging is often a cause as well. Dryness of our eyes is often due to a decrease in the oil production in our eyelid glands which causes the surface of the eye to become irritated. Certain medications and health issues can also contribute to dryness. There is no true cure for dryness but many treatments are available such as the use of artificial tears, nutritional supplements incorporating Omega 3, prescription medications such as Restasis, and eyelid hygiene. No single treatment works for every individual so we customize treatments for each person and their specific 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.
Q: What are some of the symptoms of Dry Eye?
A: There are numerous symptoms of dry eye disease, but the most common ones include excess tearing, lack of tearing, burning, redness, foreign body sensation, intermittently blurred vision, and an inability to tolerate contact lenses. If you have any of the above symptoms, and want a professional diagnosis, please make an appointment here.
