Types of Lenses and Their Care: Here's What You Should Know

When you are buying lenses for the first time, you need to be a bit more careful than you usually are while choosing frames for your specs. After all, this time it’s your comfort that is going to decide whether you are going to be happy with the lenses or not. With so many choices for coatings and lenses available you may get confused for the start.

Types Of Lenses/Coatings

Glass lenses were the only options in the earlier days that were used for vision correction. But they are heavy and tend to break very easily and hence may cause harm to the eye. Instead, other types of lenses like plastic lenses, polycarbonate lenses, or high-index plastic lenses are a better option. Made from CR-39 plastic, the plastic lenses are highly popular as they are lightweight, cheap and offer excellent optical qualities.

Polycarbonate lenses introduced in 1970 are safe, even lighter than CR-39 plastic and are considered to be ideal for safety glasses and sports eyewear. High-index plastic lenses are the thinner and lighter lenses that are very much in demand today.
