BIOLOGY - Physiology - Eye and four vision problems

The video discusses the sensitivity of animals and plants to environmental changes, focusing on human senses, particularly vision. It covers four vision problems: color blindness, glaucoma, cataracts, and diabetic retinopathy, explaining their causes, effects, and potential treatments. The importance of regular eye tests and the impact of these conditions on daily life are highlighted.

• Detecting colors

Which eye condition is characterized by damage to the optic nerve due to fluid pressure?

• Glaucoma

• Color blindness

• Diabetic retinopathy
