There are a few things to consider when getting prescription lenses. The type of lens, the material, and the prescription all play a role in finding the perfect lenses for you.
Type of lens: There are three main types of prescription lenses- single vision, bifocal, and progressive. Single vision lenses are for people who need correction for one field of vision, like distance or reading. Bifocal lenses have two fields of vision- one for distance and one for reading- in one lens. Progressive lenses have multiple fields of vision in one lens, which allows for a gradual transition between distance, intermediate, and reading.
Material: The material of the lens is also an important consideration. There are two main types of materials used in prescription lenses- glass and plastic. Glass lenses are typically heavier than plastic lenses and can break more easily. Glass lenses also usually have a higher refractive index, which means they can correct vision better than plastic lenses. However, plastic lenses are more durable and scratch-resistant than glass lenses.
Prescription: The prescription for your lenses will be determined by an eye doctor. They will take into account your vision needs and prescribe the lenses that will best correct your vision.
