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: 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 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!
