Blue Light Glasses: Do You Need Reading Strength, or Just Protection?
If you spend hours a day in front of a screen — phone, laptop, TV — you've probably wondered whether blue light glasses are worth it. The short answer is yes for most people, but the more useful question is: do you need them with reading strength, or just for protection?
Here's how to tell the difference, and why it matters.
What blue light glasses actually do
Screens emit a concentrated form of blue light at much closer range than natural daylight. Over hours of exposure, this can contribute to digital eye strain, headaches, and disrupted sleep — particularly if you're on a screen in the evening.
Blue light glasses use a specially engineered lens coating to reduce exposure to specific blue light wavelengths, without dulling your view of the screen. The good ones do this without the obvious yellow tint that cheaper lenses rely on — you get the protection without your screen looking washed out.
Do you need reading strength, or not?
This is the part most people get wrong. Blue light protection and reading magnification are two completely separate things — you can have one without the other.
You probably just need protection (0.00 / no magnification) if:
• You don't currently wear reading glasses and have no trouble seeing your screen clearly
• You're under 40 and haven't noticed any change in your near vision
• You want to wear them all day, including when looking at things at a distance
• Your main concern is eye strain, headaches, or disrupted sleep from evening screen use
You probably need reading strength if:
• You already use reading glasses for books, menus, or small print
• You find yourself holding your phone further away to read text clearly
• You're over 40 — presbyopia (the natural loss of close-up focus) typically starts here
• You only need the glasses for close-up screen work, not for general use
The good news: a well-made pair of blue light glasses should be available in both. If a brand only sells theirs with reading strength, or only without, you're being forced to guess. Look for one that offers a true 0.00 option alongside magnified strengths.
What to look for when buying blue light glasses
• Lens technology: A proper anti-blue light coating bonded to the lens, not a flimsy filter laid on top — it should last the life of the glasses, not wear off.
• No obvious tint: Quality lenses block blue light without turning your screen yellow. If the lenses look heavily tinted in the box, expect colour distortion on screen.
• Scratch resistance: A scratch-resistant coating matters if you're wearing these daily and tossing them in a bag.
• Frame comfort: If you're wearing them for hours, the frame needs to be genuinely lightweight and well-balanced — not heavy plastic that pinches by hour three.
• Both options available: Reading strength and 0.00 (no magnification), so you're buying based on your actual eyes, not the brand's assumption.
MicroVision Optima Blue Light Reader
The Optima Blue Light Reader uses MicroVision's proprietary NEOX lens technology — a BPA-free polymer infused with anti-blue light properties, engineered for high light transmission so your screen stays clear and vibrant rather than dulled or yellow-tinted.
The lenses carry a scratch-resistant coating bonded using high-energy ion bombardment, the same class of treatment used in premium eyewear, for durability that holds up to daily use. Frames are hand-finished cellulose acetate with stainless steel temple hinges — built to feel like eyewear several times the price.
Available with or without reading strength, so whether you need help focusing up close or simply want to protect your eyes during long screen sessions, there's a version built for you.
MicroVision has been designing precision eyewear since 2001, with over a million pairs sold worldwide.
Frequently asked questions
Will blue light glasses help me sleep better?
Many people find that wearing blue light glasses in the evening — particularly in the hour or two before bed — helps reduce the disruption screen use can have on natural sleep signals. It's a low-risk thing to try if evening screen time affects how easily you fall asleep.
Can I wear blue light glasses all day?
Yes, if they're the 0.00 (no magnification) version. They're designed to be worn continuously without affecting your normal vision at any distance.
Do I need a prescription to buy these?
No. Blue light glasses, with or without reading strength, are available without a prescription. If you're unsure which reading strength suits you, a simple online reading test or a chat with your optician can help.
