Congratulations, you've made it to Lesson 6 where we're finally going to start talking about glasses! This lesson will focus mostly on nearsightedness but you will also learn about much lesser known 'condition' known as emmetropia. This lesson will continue to build on everything we've learned in Lessons 1-5. So if you haven't done so … Continue reading The Optics of Vision – Lesson 6: Emmetropia & Myopia
The Optics of Vision – Lesson 3: Lens Power
Now that we understand light and lenses, we will be learning about how to quantify the effect that lenses have on light. This is the concept of lens power and it will put us well on our way to understand vision and glasses work. To understand the concepts covered in this lesson, it is best to … Continue reading The Optics of Vision – Lesson 3: Lens Power
The Optics of Vision – Lesson 2: Introduction to Lenses
In this lesson, we will be learning about what lenses are and how they affect the path of light rays. Understanding lenses will be crucial in understanding how the eyes produce vision as well as how glasses work. To understand the concepts covered in this lesson, it is best to have read: ==> The Optics of … Continue reading The Optics of Vision – Lesson 2: Introduction to Lenses
The Optics of Vision – Lesson 1: Understanding Light
What Is Light? Most of us think of light as just the opposite of darkness. It's what illuminates our world and allows us to see. If there's too much light it hurts our eyes. If there isn't enough light we can't see. Seems simple enough, right? And it is, for the purposes of this course … Continue reading The Optics of Vision – Lesson 1: Understanding Light
