They work — but not for the reason most brands advertise them. The evidence for blue light glasses reducing eye strain is modest at best. What they genuinely do well is block short-wavelength light in the evening, which directly interferes with melatonin production and disrupts sleep. After 20 years in clinic, the patients I see getting the most benefit are those using amber-tinted lenses 2–3 hours before bed. If you're wearing clear lenses during the day hoping to cure eye strain, the bigger issue is usually screen distance, blink rate, and dry eye — not blue light itself. That said, a well-made lens like Ocushield's does reduce glare and contrast fatigue, which makes long screen days more comfortable. Think of them as a genuine tool used correctly, not a cure-all.

Clear lenses filter up to 54% of blue light and are designed for daytime use — office work, school, long hours at a computer. They won't distort colour on your screen or make your environment look yellow, which matters if you're doing design work or anything colour-sensitive. Amber lenses block significantly more blue light — typically 80–98% — and are specifically designed for evening use, 2–4 hours before bed. The amber tint is a trade-off: your screen will look warmer, but the effect on sleep quality is meaningfully stronger. My recommendation is clear for the workday, amber when the sun goes down. If you only want one pair and you struggle with sleep, go amber.

Night mode on your device shifts the colour temperature of your screen — it's better than nothing, but it's a software approximation. It doesn't reduce glare, it doesn't address the physical distance between your eyes and the screen, and the blue light reduction it provides varies significantly between devices with no standardised measurement. A quality screen protector like Ocushield's is medical-device rated and blocks specific wavelengths at a consistent, tested level. It also reduces reflective glare, which is one of the main drivers of eye fatigue in lit offices. I use both — night mode as a baseline habit, a screen protector for the hours I'm working. They address slightly different problems and work better together than either does alone.

If you're using eye drops more than four times a day, you need preservative-free. Full stop. The preservatives in standard eye drops — particularly benzalkonium chloride (BAK) — are toxic to the ocular surface with repeated daily exposure. They're fine for occasional use, but for anyone managing chronic dry eye, they compound the problem over time. I've seen patients in clinic whose dry eye was being actively worsened by the preserved drops they were using to treat it. Beyond frequency, I'd also recommend preservative-free drops if you wear contact lenses, have had any eye surgery, have blepharitis, or have been diagnosed with meibomian gland dysfunction. When in doubt, preservative-free is simply the safer long-term choice — there's no downside to avoiding preservatives, and the upside for sensitive or compromised eyes is significant.

For the right conditions, yes — and the evidence is stronger than most people realise. The AREDS2 clinical trial, which forms the basis of formulas like Macutec, demonstrated a 25% reduction in the risk of advanced age-related macular degeneration in high-risk patients. That's a meaningful number. For dry eye, omega-3 supplementation has solid clinical backing for improving tear film quality, particularly the triglyceride form found in Lacritec. Where supplements don't work is when people expect them to act like drops — fast and symptomatic. Supplements work on the underlying physiology, which means you need to take them consistently for at least 3 months before assessing whether they're helping. The patients I see giving up after 4 weeks haven't given the supplement a fair trial. If you have a specific concern — macular health, dry eye, digital fatigue — there is likely a formula relevant to your situation. Every supplement I stock at Eyehouse has a clinical rationale behind it, not just a marketing claim.

Yes — and for supplements specifically, I'd strongly encourage it. Macular protection and omega-3 supplementation only work when they're consistent. Stopping for a month because you forgot to reorder doesn't just pause the benefit — for conditions like AMD, it partially resets the protective effect you've been building. Auto-Replenish is available on all supplements in the Eyehouse range. You choose your delivery frequency, save 10% on every order, and can pause or cancel anytime with no fees. It's not there as a revenue play — it's there because I've watched too many patients in clinic tell me they "ran out a few weeks ago." For something you're taking to protect your long-term vision, running out shouldn't be an option.

Most products in the Eyehouse range are either contact lens safe or have a clear recommendation on the product page about timing of use. As a general rule: preservative-free eye drops like HYLO Forte and HYLO Eye Drops can be used directly with soft contact lenses in — no need to remove them first. Preserved drops should always be used with lenses out and a 15-minute wait before reinserting. For eyelid wipes and foam cleansers, apply with lenses out as part of your morning routine before you insert your lenses, not after. Eye-safe cosmetics from brands like Eyes Are The Story and ZeroZero are formulated to be contact lens compatible, but I'd always recommend applying mascara and liner after inserting lenses to avoid transfer onto the lens surface. If you're ever unsure about a specific product, the Eye Friendly Rating on every product page includes contact lens compatibility guidance — or email us directly and I'll give you a straight answer.

The Eye Friendly Rating™ is a system I built because I got tired of seeing patients buy products marketed as "gentle" or "natural" that contained ingredients I'd never recommend near an eye. Every product we assess goes through a clinical checklist built around ingredient safety, known irritant profiles, and alignment with the TFOS DEWS II and III international dry eye guidelines — the same evidence base I use in clinical practice. Products are rated Bronze, Silver, Gold, or Platinum depending on how cleanly they pass that checklist. Bronze means safe for general use but may contain ingredients like essential oils, silicones, or natural fragrances that some sensitive eyes react to. Platinum means I'd recommend it without hesitation to a patient with dry eye disease, blepharitis, or post-surgical sensitivity. You'll see the rating on every product page, and you can filter by EFR level within any collection. It exists for one reason: so you can shop with the same confidence a patient has when I hand them something across the desk in clinic.
