Explore the Types of Prescription Lenses to Fit Your Needs
When buying eyeglasses, many make the mistake of placing too much emphasis on the style of the frames instead of choosing the correct lens that will provide the most comfort. The lenses impact four key components: Vision, comfort, safety and appearance.
Single Vision Lenses
Single Vision Lens is one power from side to side prescribed by an Optometrist to correct astigmatism, farsightedness, and nearsightedness. Single vision lenses designed for those needing one field of view such as distance, near vision, and intermediate and are the most common lenses used.
Bifocal Lens are multifocal that get split into two sections of the lens where the lower half is a design for reading up close, and the upper half that has been designed for when driving or seeing far distance. The most common types of users are those with an age-relation condition known as presbyopia hindering a users focus.
As the name suggest, Trifocal Lens use three split-levels of vision similar to bifocals aside from the third addition. The upper is a design for near distance, the bottom is for far distance, and the middle is for intermediate or mid-range when the user needs to focus on an object at arm’s length. Commonly used for individuals that spend hours in front of the computer.
Progressive lens are similar to trifocals as they allow the user to see in three different powers in any distances without the lines that bifocals and trifocals utilized that aren’t too flattering. These lenses make it to where you don’t need to carry three sets of glasses around for different vision uses or wear glasses that have unsightly lines. All you have to do to enjoy the three stage transitioning powers is adjust your head position.
Anti-Reflective lenses works as a coating applied to the lenses which assist in nighttime driving as some people experience a halo effect when looking at streetlights, headlights, and the coating provides relief from this distraction by making everything a lot more sharp by reducing reflection. It also reduces eyestrain from sitting in front of a computer too long.
Photochromic (Transitional) Lenses
Photochromic lens typically referred to as transitional lenses exhibit a color change going from dark in outdoor sunlight and transition to clear in indoor lighting. Ideal for those that use prescription sunglasses and indoor prescription glasses. It responds to molecular material from the wavelength radiation.
