Human eye structure teaching model Eye anatomy model Ocular lens disease demonstration teaching
In the human eye there is a double convex transparent body called the lens.
A cataract is a clouding of the normally clear lens of the eye.
For people with cataracts, seeing through a cloudy lens is like looking through a frosted or foggy window.
Blurred vision from cataracts can make it difficult to read, drive (especially at night), or see the expressions on a friend’s face.
Cataracts do not interfere with vision in the early stages, but they will eventually affect vision over time.
Cataract is a common disease in the elderly in China, and it is also the main blinding eye disease in China.
Cataract symptoms include:
1, vision is cloudy, fuzzy, fog or film.
2. Changes in the way you look at colors (colors may look faded or less vibrant)
3, sensitive to strong light sources such as sunlight, headlights or lights.
4. Glare, including halos or streaks formed around lights.
5. Difficulty with night vision.
6. Need brighter light to read/double vision.
