Eyezen lenses: How they work, lens types and benefits
What are Eyezen lenses?
Eyezen is an everyday lens that provides comfort and protection for people who use smartphones, tablets and computers for extended time periods. The enhanced single-vision lens filters at least 20% of harmful blue light emitted by digital screens and works to reduce digital eye strain symptoms.
How blue light affects vision
When you consider how often you look at digital screens and how closely you view them, it makes sense that your eyes could be negatively affected in some way.
Light passes through the cornea of the eye and is directed toward the retina at the back of the eye. It’s believed that frequent blue light exposure can cause cumulative damage to the retina over an extended period of time.
A short-term issue that can be caused by blue light exposure is digital eye strain, which presents symptoms such as:
Neck and shoulder pain
Retinal damage can accumulate over time. This can potentially lead to serious vision conditions, including macular degeneration. Fortunately, eye doctors and researchers have developed products, such as Eyezen lenses, to protect the eyes from prolonged exposure to blue light and combat symptoms of digital eye strain.

How Eyezen lenses work
Eyezen lenses are made using cutting-edge technology that incorporates several different mechanisms:
Eyezen Focus – Eyezen lenses have a small amount of magnification to allow you to maintain a proper working distance from your screen and avoid holding it too close.
Blue light filtering technology – This protects the eyes from blue-violet light emitted by digital screens, preventing 20% of blue light from entering the eyes.
Wavefront Advanced Vision Enhancement (W.A.V.E) Technology – Used to give each lens a unique design, W.A.V.E. Technology provides clarity at any distance, eliminating blur even with poor lighting. Lenses are customized based on your individual single-vision prescription for each eye.
The result of this technology is an Eyezen lens that helps relax and protect your eyes. These lenses allow you to view your digital screens more comfortably, providing clearer near vision and reduced eye strain. In addition, wearers have improved contrast perception and diminished glare.
Eyezen lenses are designed to be worn all day, and can even benefit patients who do not typically wear prescription glasses.
Eyezen Start is a single-vision lens that uses two different points on the lens to deliver different surfaces for distance and near vision. This technology optimizes the area of the lens that provides clarity to the patient. This single vision lens is ideal for all types of digital use in the modern home and workplace.
The added blue light protection of Eyezen Start lenses keeps the eyes safe from blue-violet light and comfortable when using a digital device.
Eyezen + lenses are enhanced single-vision lenses used to combat digital eye strain. For those who want an extra boost in their single-vision lenses, Eyezen + may be the perfect fit. Eyezen + lenses are created with four different accommodation (eye focusing) levels. This provides a small amount of magnification for easier, sharper focus of close viewing distances for more comfortable reading.
The magnification levels of Eyezen + are determined by the diopter strength. The higher the diopter, the stronger the prescription. All Eyezen lens designs have blue light filtering properties. Eyezen + lenses are recommended for people who experience frequent symptoms of digital eye strain.
Eyezen + 0 – Typically recommended for children 17 and under, this lens has 0.00 diopters. This means there is no added magnification but it does have blue light blocking properties.
Eyezen + 1 – People aged 18 to 34 benefit most from a small level of magnification — 0.40 diopters to be exact.
Eyezen + 2 – The power level for Eyezen + 2 lenses is 0.60 diopters, which is suggested for people aged 35 to 44.
Eyezen + 3 – The highest enhancement currently available for Eyezen + lenses is 0.85 diopters. It’s recommended for people aged 45 to 50 who do not yet need progressive lenses or bifocals for presbyopia.
The age ranges listed above are suggested by the manufacturer. However, your eye doctor will prescribe the best Eyezen + accommodation level for you based on your specific needs.
People over the age of 40 who are beginning to experience symptoms of presbyopia may benefit more from a pair of Varilux lenses than Eyezen + 3 lenses. Consult with your eye doctor to learn more and find the lenses that best meet your needs.
