Week 3 Forum

Many people wear glasses to compensate for the fact that the optical system of their eye does not focus a sharp image on the retinas. Once you have reviewed the videos below, discuss at least three of the disorders of focusing. Be sure that you are discussing the complete epigenetic origin which should include a discussion of the genetic/biological origin and the environment influence related to these disorders of focusing. Include in your discussion the impact of culture in the development of the optical system at various stages of the lifespan. Support your belief and use specific examples.

The disorders of optical focusing

Introduction

The eyes are incredible and important, take care of them.

Myopia (Nearsightedness)

Myopia (Nearsightedness)

Myopia is the most common vision disorder. It’s caused by a refractive error of the eye that causes distant objects to appear blurry. Sometimes it’s just genetics, but near-work activities can also cause myopia in some people.

Hyperopia (Farsightedness)

Hyperopia (farsightedness) is the opposite of nearsightedness. The eye is longer than it should be, and therefore you can see objects farther away than they would appear if your eyes were normal.

This can happen to anyone—even people who are born with this condition, because their lenses are weak enough that they don’t focus as well as other people’s do. You may experience some symptoms when looking at something far away: blurry vision, difficulty focusing on things close-up and distant objects at the same time, or feeling like there’s a heavy curtain in front of your face blocking out everything else around you!

Astigmatism

Astigmatism is an eye condition that causes blurred vision. It’s caused by an irregularly shaped cornea, which means that the light entering your eyes needs to be funneled through different parts of your retina in order to focus on objects at different distances.

To correct astigmatism with glasses or contact lenses, you should go to an optometrist and have them check your prescription. Your optician will determine if you need reading glasses or sunglasses for distance and near vision correction; if so, they’ll recommend a type based on how much correction is required for each type of eye health issue (e.g., cataracts).

If you don’t need reading glasses but still want some extra help with close-up vision tasks like reading small print or watching movies at home (which may not have good lighting), then consider purchasing some plastic lenses from Amazon instead—these can be found under “contact” according to their materials page!

The eyes are the window to the soul, but they can become damaged easily by UV rays, chemicals or radiation. You may be able to see through your lens or glasses just fine if they’re not broken yet (or if you have corrective lenses), but if any part of your eye is damaged or has been broken in any way, then each layer of tissue will need to heal before it can be healed correctly again. This means that there could be slight changes in vision after surgery—just keep in mind that this will happen with any kind of procedure like this one!

Conclusion

We hope this article has helped you to understand more about your eyes and how they work. As we’ve seen, there are many different types of eye disease, but it’s important to remember that each one can be treated differently depending on your symptoms.
