What Is Eyezen 2 and How Does It Reduce Eye Strain?

Eyezen 2 is a single-vision lens made by Essilor that includes a small built-in power boost of +0.60 diopters near the bottom of the lens. This extra power reduces the effort your eyes need to focus on close-up objects like phones, tablets, and computer screens. It sits between the milder Eyezen 1 (+0.40 diopters) and the stronger Eyezen 3 (+0.85 diopters) in Essilor’s lineup of enhanced single-vision lenses.

How Eyezen 2 Differs From Regular Lenses

A standard single-vision lens corrects your distance vision uniformly across the entire surface. Eyezen 2 does the same thing in the upper and middle portions of the lens, but adds a slight bump in focusing power toward the bottom. When you glance down at a screen or book, the lens picks up some of the focusing work that your eye muscles would normally handle on their own. The +0.60 diopter addition is subtle enough that most wearers don’t notice a visual transition the way they would with a progressive or bifocal lens.

This design is sometimes described as “a type of progressive,” but that’s a loose comparison. True progressives have a continuous gradient from distance to near vision and are built for people who already need reading correction. Eyezen 2 is aimed at younger adults, typically in their 30s and 40s, whose distance prescription is still their primary need but who experience fatigue during long stretches of screen work.

The Eyezen Lineup at a Glance

Essilor offers several tiers, each with a different level of near-vision support:

  • Eyezen Start (and Eyezen+ 0): No added reading power. Uses a freeform digital design to optimize clarity across the lens, especially when your eyes move away from the optical center. Think of it as a better-engineered single-vision lens rather than a lens with a boost.
  • Eyezen 1: +0.40 diopters of added near power. The mildest boost, suited for lighter screen users or those just beginning to notice eye fatigue.
  • Eyezen 2: +0.60 diopters. A moderate boost for people who spend several hours a day on digital devices.
  • Eyezen 3: +0.85 diopters. A stronger boost, often recommended for heavier screen use or slightly older eyes that need more accommodative support.
  • Eyezen 4: +1.10 diopters. The strongest option before stepping into a traditional progressive lens.

Your eye care provider picks the level based on your age, how much near work you do, and how your focusing system performs during an exam.

What the Research Shows About Comfort

A clinical study published in the Revista Brasileira de Oftalmologia tested Eyezen lenses with a +0.40 boost (the Eyezen 1 level) on people experiencing screen-related eye strain. After four weeks of wear, participants’ overall eye strain scores dropped from 17.4 to 13.2 on a 60-point scale, a statistically significant improvement. Specific symptoms that improved included dryness, eye strain, burning sensation, blurred vision, and general visual discomfort. More than 90% of participants said they were satisfied or very satisfied with their visual comfort.

That study tested the +0.40 level, one step below Eyezen 2. The +0.60 boost in Eyezen 2 provides even more accommodative relief, which in theory should offer at least comparable symptom reduction for people whose eyes benefit from the extra support. No published study has isolated the +0.60 level specifically, but the mechanism is the same: less muscular effort to focus up close means less fatigue at the end of the day.

Who Eyezen 2 Is Designed For

The typical Eyezen 2 wearer is someone in their mid-30s to mid-40s who doesn’t yet need a progressive lens but notices that their eyes feel tired, dry, or strained after hours of screen use. At this age, the eye’s natural focusing ability starts to decline gradually, even if you can still read fine print without help. The +0.60 boost compensates for that early decline without committing to the wider power range of a progressive.

If you’re in your 20s with mild screen fatigue, Eyezen Start or Eyezen 1 is usually sufficient. If you’re approaching your late 40s and already struggling to read restaurant menus, you may be past the point where a small single-vision boost helps and a progressive lens makes more sense. Eyezen 2 fills the middle ground.

What to Expect When Wearing Them

Most people adapt to Eyezen 2 within a few days. The +0.60 addition is gentle enough that you won’t see a visible line or experience the “swimming” sensation that some first-time progressive wearers describe. Distance vision through the upper part of the lens feels identical to a standard single-vision lens. When you look down at your phone or keyboard, images may appear slightly sharper and more relaxed than what you’re used to.

Eyezen lenses are freeform designs, meaning they’re digitally surfaced to your exact prescription rather than molded from a stock blank. This generally results in wider areas of clear vision and less peripheral distortion. They can be paired with various coatings, including blue-light filtering options, though the core benefit comes from the power boost itself rather than any coating.

Pricing varies by provider and coating choices, but Eyezen lenses typically cost more than basic single-vision lenses and less than premium progressives. Many vision insurance plans cover them the same way they cover standard lenses, though higher-tier coatings may carry an additional out-of-pocket cost.
