How Smoking Impacts Vision

Smoking harms nearly every system in your body — including your eyes. 

Though we are all aware of the health effects associated with smoking, such as lung cancer, heart disease, and bad teeth, few know about the negative impact it can have on our vision. 

Smoking and Eye Disease 

Smoking can adversely impact your vision. Drs. Leong, Yung and Bui have observed that in the short term, the fumes can irritate the eye surface but over the long term internal structures within the eye degenerate. 

More specifically, tobacco addiction increases the risk of developing vision-robbing diseases such as macular degeneration (AMD), cataracts, glaucoma, diabetic retinopathy.  Below we'll delve a little further into each of these conditions. 

Age-Related Macular Degeneration (AMD)

Smokers run a high risk of rapid progression of AMD, a condition that severely impairs central vision, making it difficult or impossible to read, drive, recognize faces and colors, and leads to permanent vision loss in those aged 65 or older. Many people with AMD take vitamin supplements to counteract the degenerative changes.  Caution for smokers, who should not take beta-carotene supplements as this increases the risk of lung cancer in smokers (even if one stopped smoking for up to five years!)

Cataracts

Heavy smokers double their risk of developing cataracts, the leading cause of blindness. Cataracts are characterized by clouded, blurred or double vision, photophobia, and reduced night vision. However, cataract surgery is common and replaces the clouded lens with an artificial intraocular lens. 

Uveitis

Uveitis, the inflammation of the eye's central layer, is an ocular disease that can lead to blindness. This condition damages important structures of the eye, notably the iris and retina, and can lead to cataracts, glaucoma and retinal detachment. Smokers have a 2.2 times higher risk of developing uveitis than non-smokers. 

Diabetic Retinopathy

Smoking raises one's risk of developing diabetes by up to 40 percent thereby increasing the risk of retinopathy as well. Diabetes damages the blood vessels in the retina, causing them to leak blood into the eye, which — in severe cases — can deprive the retina of oxygen and result in blindness.

Dry Eyes

Dry eye syndrome is a common eye condition characterized by insufficient tears to keep your eye lubricated, or the tears are not composed of the correct balance of water, lipids, and mucous to maintain proper lubrication. Common symptoms include red, itchy, and gritty eyes.

Heavy smokers, and those exposed to secondhand smoke, not only double their risk of developing dry eye but also exacerbate an existing condition, especially among the contact lens wearers.

Secondhand Smoke and Eye Disease 

Secondhand smoke— which includes the smoke that emanates from the end of a cigarette as well as the smoke exhaled— is nearly as harmful to health and vision. Second-hand smoke places others' eyesight in danger, particularly in young children and infants. Furthermore, studies indicate that women who smoke during pregnancy put the newborn baby at risk of being born with eye disease or visual impairment that could affect his or her ability to learn.

Stop Smoking to Save Your Vision

The good news is that giving up smoking can have an immediate effect on your health — and it’s never too late to quit! Once the habit is broken, your body will begin to repair itself to prevent vision loss. It can be challenging to quit, as it requires dedication, support, and advanced planning. Drs. Leong, Yung and Bui and the rest of the staff at Foresight Eyecare in NorthWest Calgary care about your health and will be happy to provide any assistance or resources to help you quit smoking and improve your eye health. Keep in mind that if you smoke, quitting smoking is the most important step you can take to protect your health and vision.

Thank you for trusting your eyecare with us over the years.  The Foresight Eyecare team follows the government mandate to reduce the spread of the COVID-19 pandemic.  After December 2020 announcements made by the Alberta Government, our clinic is following the revised Infection Prevention and Control policy by the Alberta College of Optometrists.

Patients interested in obtaining eye exam services or eye care products can be seen by appointment only.  Please call ahead, and staff will arrange an appointment time and ask COVID-19 screening questions.  If you have any symptoms of cough, fever, runny nose or shortness of breath, we ask that you call or e-mail us and do not attend the clinic for your scheduled visit.   Within the clinic, please wear a mask and use the hand sanitizer at reception.  Our clinic complies with the City of Calgary bylaw requiring mask covering over the age of two years old.  For patients who are unable to wear a face covering due to medical reasons, the patient can be scheduled for an appointment at a time when minimal number of other patients are in the clinic such as at the beginning or end of the day to ensure appropriate physical distancing requirements.

We are using disposable disinfectant wipes on all surfaces and devices such as front desk counters, chairs, handles in exam rooms and waiting room.  All eyewear that have been touched by patients are continually being sanitized.   Any toys and magazines are stored at this time.  Examination areas are being sanitized with hospital grade disinfectant.  Debit and credit cards but NO CASH payments will be accepted.

COVID-19 symptoms are not always obvious.  We want to fend off this pandemic and minimize risk to our patients and the Foresight staff as front line health workers.   Contact that is closer than 2 m (6 feet) is to be avoided, with barriers in place when this cannot be avoided. We choose to continue to do our work and cautiously take care of our patients with compassion, humility, gentleness, and patience.   It is a challenging and new experience for many of us, so let‘s support each other and prevent virus spread!  Beyond 2020, our focus is on take care of you and keeping Clean Hands, Clear Heads and Open Hearts.   For more information, please refer to the following web pages or phone Health Link 811.
