Understanding Vision

Good vision is multi-faceted – find out more about the basics of the way people see and what vision aids can help.

Sight is the most important of the five senses: The complex interaction between the brain and our eyes helps us see the world around us and all its details throughout our lives. That’s why excellent vision is essential when it comes to ensuring a high quality of life. Glasses play a major role in helping us achieve this aim. Read on to find out all about the way people see and what that involves, e.g. the anatomy of the human eye, diseases and visual impairments such as red-green colour deficiency, and glasses. We’ll also give you a few tips on coatings. For instance, did you know that there are many different types of lenses and lens designs and that many people can see better if they wear customised glasses?
