- Changes the shape of the cornea to focus the light on the retina more efficiently by removing the inner layer of tissue from the cornea.
- It is recommended that this is done once the optic error has stabilised.
- The possible outcomes of surgery are that it decreases or eliminates the usage of glasses/ corrective lenses.

There are two main parts of the eye that change when it focuses on near and far objects; the lens and the ciliary muscles.
Lens
The crystalline lens, which is behind the pupil, is responsible for focusing the light that enters the eye. By adjusting its’ focal length, the lens allows you to focus on objects that are close, and those that are far away but not both at the same time. This is achieved by the lens bending and changing shape because of the ciliary muscles.
Ciliary Muscles
The ciliary muscles are attached to the lens by ligaments within the eye. These muscles can contract and relax, and by doing so, they alter the shape of the lens. When these muscles relax, the lens flattens, allowing the eye to focus on objects in the distance. When they contract the lens curves more so that the eye can focus on objects that are close.…show more content… Echolocation is more effective for navigating and detecting objects than sight and other senses at night. As a result, the bats auditory system is an small/intricate structure designed to work with high frequencies.
Animals such as the cow and humans, are active during the day meaning that they don’t need to rely as heavily on their auditory systems as nocturnal animals because their other senses. In their environment, the primary senses used are sight and smell.

The information gathered is reasonably reliable for most questions as the same data was found over at least 3 different sources. Questions such as 7, are less reliable as information did vary from source to source, hence an average of the numbers found was used.
The information collected is also fairly valid as it is relevant to the question being asked, the majority of data was published recently and many sources used were government, educational or scientific resources. However, the validity was lowered as some sources’ data was over 5 years old and it was difficult to establish whether some of the data was from a reputable publisher or
