Empower your eyes. Instant relief.
Prescription glasses for light sensitivity. Adjust your tint instantly to combat migraines, photophobia, and harsh glare.
What is photophobia?
Photophobia is a condition that causes extreme light sensitivity, leading to discomfort or actual physical pain when exposed to bright light. It is commonly associated with migraines, dry eyes, and post-surgery recovery.
Why existing solutions fail
Carrying around indoor blue-light glasses and outdoor sunglasses is inconvenient. Standard transition lenses react far too slowly—leaving you vulnerable to sudden bright sunlight or agonizing fluorescent office lights while you wait minutes for them to adapt. You need active, immediate control.
Speed is everything.
When a migraine hits or the sun breaches the clouds, waiting minutes for transition lenses to adapt is not an option. You need immediate defense.
Engineered for every environment.
Migraine Onset
At the first sign of an aura or migraine, tap the frame to instantly darken the lenses and protect your vision from triggering glare.
Post-Surgery
Following LASIK or cataract surgery, light sensitivity peaks. WaSun allows granular control over your tint to aid recovery indoors and out.
Harsh Office Lights
Fluorescent lighting is a major trigger. Set your photophobia glasses to a subtle 20% tint to cut overhead glare while remaining professional.
Driving Blinding Sun
Unlike transition lenses, WaSun activates inside the car. Protect your eyes from blinding reflections and direct sunlight while driving.
Digital Screens
Even in clear mode, the base optical layer filters out harmful high-frequency blue light, reducing digital eye strain from long hours in front of monitors.
Do transition (photochromic) lenses work indoors?
Standard photochromic lenses — often called "transition" lenses — are designed to react to UV light. Ordinary indoor lighting doesn't produce enough UV to activate them, so they typically stay clear once you're inside. This is fine for most people, but if you're sensitive to bright indoor lighting — fluorescent overheads, harsh LED spotlights — photochromic lenses generally won't darken in response to ordinary indoor lighting.
Most standard photochromics also don't darken noticeably behind a car windscreen, since modern windscreens block much of the UV they rely on. Some newer photochromic variants are designed to activate in cars, but this remains a limitation of the technology overall.
Electrochromic lenses like WaSun's work differently. Instead of reacting to UV, they respond to a small electrical signal from a control on the frame, so tint is on demand. You decide when to tint — indoors, outdoors, in the car, whenever you want.
Light-sensitivity glasses vs regular sunglasses
Regular sunglasses reduce brightness. They're designed for outdoor daytime use with a fixed tint.
Glasses for light sensitivity often need to work in changing conditions, indoors as well as out, and let you have clear vision when you want it. Someone with photophobia might need tint in a busy supermarket at midday and no tint five minutes later at home.
The mismatch is why many people with light sensitivity end up switching between multiple pairs of glasses throughout the day — one prescription pair for reading, one prescription sunglass pair for going out, sometimes a fixed-tint indoor pair too. That can be inconvenient and may mean owning multiple pairs.
WaSun's electrochromic prescription lenses are designed to reduce the need to switch between different pairs, giving you clear or tinted vision from a single frame on demand.
How to choose glasses for light sensitivity
A few things worth considering when comparing options:
How the tint is triggered
Photochromic lenses depend on UV to darken, which means they respond to your environment rather than to you. Electrochromic lenses respond to a control on the frame, so you choose when tint is active.
Indoor performance
Because most indoor lighting doesn't emit enough UV, photochromic lenses typically stay clear inside. If your sensitivity is triggered by fluorescents or bright LEDs, on-demand tint control is more useful.
Prescription compatibility
Some tinted lenses aren't available with prescriptions, or require costly custom orders. WaSun's lenses are prescription-compatible.
Personal control
Fixed-tint lenses give you the same tint regardless of context. Electrochromic lenses let you switch between clear and tinted whenever you need to.
Frame comfort
Anything you'll wear all day matters more than any spec on paper. WaSun is designed as everyday eyewear rather than a specialist medical device.

What are FL-41 lenses, and how does electrochromic tint compare?
FL-41 is a rose-tinted lens filter designed to reduce certain blue-green wavelengths. It has been studied for light sensitivity, including in people with migraine and some other conditions, although individual responses vary.
The main practical difference between FL-41 and electrochromic lenses is control:
- FL-41 lenses have a fixed tint. The filter is always on, which suits people who want the same tint constantly, but limits flexibility if your needs change through the day.
- Electrochromic lenses have on-demand tint. You choose when the tint is active.
Neither approach is universally better — they suit different people and different situations. Some people wear FL-41 lenses in specific settings and switch to different eyewear otherwise. If you're unsure what would be right for you, this is a good conversation to have with an optometrist.
