5 Things That Can Affect Your Eye Colour

Typically a person’s eye colour becomes permanent about three years after birth.

However, several factors can change the colour of a eye to a different pigment.

Here are five of them:

1. Increased Sun Exposure

When your eyes are exposed to sun or light, it causes the body to produces more melanin.

Melanin is a skin pigment that is present in both humans and animals and it is responsible for making the skin, hair and eyes appear darker.

Presence of Melanin will make the eyes appear a darker shade of brown or grey depending on your current colour of your eye.

2. Changes In Pupil Size

The pupil shrinks when exposed to bright light, whereas it grows in dimmer lighting.

When the pupil changes size, the pigments in the iris either compress or spread apart which causes a slight change in perceived eye colour.

3. Pigmentary Glaucoma

For this type of Glaucoma, the pigment on the back of the Iris is disrupted and the loose pigment granules collect on the back of the cornea.

This loose pigment could also collect on the front of the iris, changing the colour.

4. Glaucoma Medication

Glaucoma medication called prostaglandins can cause permanent eye colour changes, usually making the eyes.

A darker shade of their natural colour over time.

5. Horner’s Syndrome

This is a complication with the third cranial nerve.

This disease could make the affected eye(s) change to a lighter colour.

What Do Experts Say About The Changes in the colour of your eyes?

Reports gathered from some eye doctors have revealed that human’s eyes do not just change colour.

However, some external factors with your genetics may determine how the colour of your eye looks at any given time or day.
