Single vision lenses explained: how to pick between Essilor, Shamir, Nikon, and Tokai

Single vision is the lens most Filipinos actually wear: one prescription, one focal power, correcting either near or far. That simplicity is exactly why the choice gets confusing at the counter. Essilor, Shamir, Nikon, and Tokai all make single vision lenses, and they are not interchangeable labels for the same thing. Here is what actually separates them, in plain terms.

What "single vision" means, and what it does not

A single vision lens has one power across the whole lens, correcting myopia, hyperopia, or astigmatism at one distance. It is different from a progressive, which blends multiple powers into one lens for presbyopia. If your prescription has no "ADD" power listed, you are almost certainly looking at single vision, whatever the frame or coating on top of it.

The fast option: Express service

Some single vision lenses are kept in stock and edged on-site, so they are ready the same visit. Basic 1.50 is Vision Express's in-stock lens, ready in 20 minutes. Opulens Advanced 1.60 and Opulens Ultra 1.60 are also in stock and ready in 20 minutes, with a higher index for a slightly thinner lens at higher grades. If you need glasses today, these three are the ones to ask for by name.

Made-to-order tiers: Starter, Enhanced, Best

Everything else on the single vision menu is made to your exact prescription at the lens brand's own lab, which is why the wait is longer and the result is more precise:

• Starter — Essilor Blue Light Single Vision, made in France, 3 to 5 days; and Shamir Opulens Exact, made in Israel, 7 to 9 days.
• Enhanced — Nikon Seemax Infinite Z, made in Japan, 3 to 5 days; Shamir Smart SV III As Worn, made in Israel, 7 to 9 days; and Tokai BIR-W, made in Japan, 10 to 12 days.
• Best — Tokai HR-W, made in Japan, 10 to 12 days, our thinnest single vision option for stronger prescriptions.

How the brands actually differ

Essilor is the fastest-turnaround made-to-order option and includes a blue light filter for screen comfort. Shamir Opulens Exact is measured to your exact frame and face, which matters if your prescription has astigmatism, since the cylinder and axis get cut precisely rather than generically. Nikon Seemax Infinite Z is built with night driving in mind, cutting down on glare and halos around headlights. Tokai's BIR-W and HR-W are Japan's answer to strong prescriptions, keeping the lens thin and light instead of thick at the edges. None of these is objectively "better" than the others. The right one depends on what your eyes actually need.

Which one fits you

• Everyday wear, no special concerns, need it today: Basic 1.50 or Opulens Advanced 1.60.
• Long screen hours: Essilor Blue Light Single Vision, or Opulens Blue Light 1.56 if you want it in stock.
• New or changed prescription with astigmatism: Shamir Opulens Exact.
• Night driving discomfort: Nikon Seemax Infinite Z.
• Strong prescription, want the thinnest lens possible: Tokai HR-W.

Get the prescription right first

The lens brand only matters once the prescription behind it is accurate. Book a Vision7 eye test at your nearest Vision Express store. It is our seven-step comprehensive exam, and it is what determines whether you actually need single vision, whether astigmatism is part of your grade, and which single vision lens on this list matches your day-to-day life. Ask for the lens by name at the counter, and the optometrist who ran your exam can confirm it is the right fit. Every pair comes with a 1-year warranty, plus free lifetime ultrasonic cleaning and custom fitting and adjustment for as long as you own it.
