For every power, there is an ideal base curve. The industry, for various reasons, doesn't strictly adhere to this principle, but it's crucial to note that base curves are still very important. As it turns out, good optics are more closely related to base curve than typically thought.

I had the honor to be the facilitator for the development of an education program “Refraction for Opticians.” You cannot understand refraction without knowing basic optics. Re-visiting trigonometry brought back memories of a lot of challenging math-moments and the glorious, “I got it,” experience.

When compared to CR-39 monomer, lenses made with Trivex material are up to 15 to 20 percent thinner and always about a third lighter. An aspheric design will further reduce thickness and weight. While there are other higher index materials that can make lenses even thinner, lightness depends on final lens volume and its specific gravity.

We all have to make cost-benefit decisions on a daily basis. Is it worth going 10 minutes out of your way to get that really good cup of coffee? If you install energy-efficient appliances in your home, will you get that return on investment?
