Question

Define myopia hypermetropia. astigmatism and herbivorous PLANTS

Answer 1

Explanation:

Both Myopia (short-sightedness) and Hypermetropia (long-sightedness) are common eye conditions that are occur when light does not focus on the retina of the eye. ... Hypermetropia (Hyperopia) means long sight and is where the image of a nearby object is formed behind the retina.

Astigmatism is a term used for the irregular shape of the surface of the eye called the cornea.

Answer 2

#Herbivorous animals:

=>An herbivore is an animal or insect that only eats vegetation, such as grasses, fruits, leaves, vegetables, roots and bulbs. Herbivores only eat things that need photosynthesis to live. This excludes insects, spiders, fish and other animals.

→There are 3 Defects of eye:

• Myopia: It occurs when the eyeball is too long, relative to the focusing power of the cornea and lens of the eye.This causes light rays to focus at a point in front of the retina, rather than directly on its surface.

• Hypermetropia: It occurs when the eye in which light is focused behind, instead of on, the retina.This results in close objects appearing blurry, while far objects may appear normal.As the condition worsens, objects at all distances may be blurry.

• Astigmatism: It occurs when the cornea (the clear front cover of the eye) is irregularly shaped or sometimes because of the curvature of the lens inside the eye.
