Eye problems can be added to the many negative effects of heavy smoking. In this post, eye doctor clinic Park Slope Eye shares a closer look at how smoking can affect your vision.
Damage to Color and Contrast Vision
The results of a study published in the journal Psychiatry Research indicate that heavy smoking can damage color and contrast vision. The sample consisted of 63 people who smoked more than 20 cigarettes a day, and 71 participants who had smoked fewer than 15 cigarettes in their lives. All participants had normal or corrected-to-normal vision.
The study results revealed a significant change in red-green and blue-yellow color vision among the participants that were heavy smokers. Difficulty in discriminating contrasts and colors were likewise observed.
Other Risks to Vision Caused by Smoking
Smoking contributes to other vision-related conditions, such as:
Dry Eye Syndrome — This condition is caused by not having enough tears to lubricate your eyes. It can make the use of contact lenses difficult.
Cataracts — A leading cause of blindness worldwide, cataracts cause blurry vision and color desaturation. Smoking increases the risk of cataract formation.
Age-Related Macular Degeneration — Damage to the macula, the part of the retina responsible for high-resolution vision under visible light, can result in loss of central vision. Studies show that smokers are at an increased risk of developing AMD, which, currently, does not have a known cure.
Diabetic Retinopathy — Smokers who happen to be diabetics have increased risk of getting diabetic retinopathy, caused by damaged blood vessels. This leads to blurry or distorted vision, even blindness.
Glaucoma — Among the various types of smoking-related risks to vision, glaucoma is at the forefront. The optic nerve connects the eye to the brain and damage to it can lead to blindness.
Uveitis — The uvea is the middle layer of the eye wall. Inflammation of the uvea is called uveitis, which is characterized by red eyes, pain, and vision problems. Studies have shown that smoking contributes to uveitis.
