An old saying claims that the eyes are the windows of the soul. No one knows where this phrase came from, but nevertheless today we know for sure that eyes can tell a lot about us and show our health condition.

We at Bright Side decided to share these observations with you.

1. Permanent sty

If you’ve ever had a sty, you know the pain and irritation it causes. A lump on the eyelid appears due to a blocked sebaceous gland and usually goes away within a few days, but it may persist, causing serious inconveniences.

If a sty pops up often or persists for a long time, it can be a symptom of sebaceous gland carcinoma. If you notice that it doesn’t heal or appears in the same place, it’s time to visit a doctor.

2. Eyebrow loss

There are lots of reasons for eyebrow loss: aging, stress, or nutrient deficiency. Alopecia areata, or spot baldness, can be another reason, though it affects no more than 0.1% of the population.

A more plausible reason for eyebrow loss is hypothyroidism — an acute shortage of thyroid hormones that in extreme cases can lead to hair loss. So if your hair is thinning, it’s better to visit your doctor and check the state of your thyroid gland.>>>READ MORE
