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 is one of 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 of ocular 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 term 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 reaction and a true infection, which can lead to faster healing with proper treatments.
Q: What exactly is astigmatism?
A: Usually it is related to the shape factor of the front surface of the eye called the cornea. Instead of being shaped spherically like a ball bearing or a marble, it is shaped like a football, being more curved in one direction than the other. This brings light to focus at more than 1 point. The root word stigma means point and the prefix A means without a point focus in the eye.
Q: What is blue light and why is it dangerous?
A: Blue light is part of visible light and close to UV on the light spectrum. It is naturally produced by the sun, used in fluorescent light bulbs and emitted by LED screens on computer monitors, tablets, and smartphones. The eyes’ natural filters do not block blue light and chronic exposure can cause age – related macular degeneration. Evidence also shows that blue light exposure can lead to sleep problems.
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: 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 conditions such as diabetic retinopathy, glaucoma and macular degeneration, etc. may not receive the full benefit of these lenses. Also, some patients with corneal scarring or those with significant astigmatism are not always the best candidates for these lens implants either. Your eye care professional can help determine if this lens implant option is right for you.
Q: What are cataracts and how can they be treated?
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 eyeglass prescription changes cannot help. When the blurriness worsens to the point that it interferes with a person’s ability to read or drive or 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, and with little down-time and excellent outcomes.
Q: What can I do about Digital Eye Strain?
A: We can help! We offer a number of different eyeglass lenses that can help people of all ages relieve Digital Eye Strain and ease fatigue after extended reading or computer use. There are also lens treatments such as anti-reflective and blue light blocking to protect our eyes and make our eyes more comfortable. We also prescribe many different types of contact lenses to make reading more enjoyable and make it easier to focus from distance to near.
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 benefits of daily disposable contact lenses are comfort, convenience and eye health. Daily lenses only stay in your eye for one day, eliminating any buildup of bacteria on the lenses that could cause infections or allergic reactions. So for patients who suffer from allergies, I recommend using dailies over monthlies, even though the cost is a bit more. Dailies also tend to be more comfortable than monthlies, partially because there is no buildup on the lens. They are also more convenient, as you just throw away the lenses after the day, and use a brand new lens the next morning.
Q: What are the advantages of daily disposable contact lenses?
A: Daily disposable contact lenses are great for many reasons. The chance of infection decreases 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 that have allergies, contact lens solution sensitivities and dry eye as it eliminates the buildup of contaminants on the lenses that can exacerbate those problems. Dailies make for a low maintenance and comfortable option for 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.
