Certain factors like diabetes, hypertension and age are known to have negative effects on vision. But, there are other, more surprising factors that can harm your eye health. Explanations.
Physical inactivity
Lack or absence of physical activity increases the risk of diabetes, high blood pressure and hypercholesterolemia.
Factors which in turn increase the risk of eye diseases. Sedentary people also tend to use screens more compared to people who engage in regular physical activity.
However, we know that excessive use of screens promotes the appearance of vision problems (myopialoss of distance vision, dry eyes, etc.).
The tobacco
The smoke emitted by cigarettes dries the eye by encouraging the evaporation of the eye’s natural moisture. Ultimately, this can lead to discomfort and dry eyes, especially if you wear contact lenses. But that’s not all !
Nicotine in cigarettes contributes to the formation of free radicals, compounds that accelerate cellular aging and promote chronic inflammation throughout the body, including the eyes.
As a result, smokers have an increased risk of developing cataracts and age-related macular degeneration. Other eye diseases like uveitis and retinopathy can be worsened by smoking.
psoriasis
Psoriasis is a skin disease that results in raised, well-demarcated red patches covered with whitish scales.
This autoimmune disease can sometimes lead to an eye disease called uveitis, which is inflammation of the uvea (the pigmented, vascular middle membrane of the eye).
It manifests itself by redness, pain triggered by exposure to bright light, increased sensitivity to light and blurred vision.
The area
Shingles is a skin disease that results from the reactivation of the chickenpox virus that was hidden in nerve cells. It causes painful blisters on the face, chest, stomach and genitals. But it can also affect the eye by causing problems in the cornea (front part of the eye).
Herpes zoster ophthalmicus, also called ophthalmic shingles, is a potentially serious variant of shingles. It affects approximately 20% of cases of shingles and most often affects immunocompromised patients.
Shingles ophthalmicus only affects one eye at a time. If it becomes complicated, it can lead to conjunctivitis, loss of vision or sensitivity to light.
