Episode notes
Blue Eyes and Light Sensitivity
- Blue eyes aren't inherently more light-sensitive than other colors.
- They have less melanin in the outer iris layer, but the inner layer, which protects from sunlight, has the same brown pigment for everyone.
Sunlight and Eye Damage
- Unprotected sun exposure can damage the eye's lens, causing cataracts.
- UV rays can also cause photokeratitis, inflaming the cornea, leading to various vision problems.
Choosing Sunglasses
- Choose sunglasses with CE marking and a lens shade category (0-4).
- Adults at the seaside need category 3, while children and those at high altitudes need 4.
