Screens strain your focussing muscle and dry out your eyes, and the cells you can't feel work under oxidative stress all day. Visor™ boosts your eyes' antioxidant defence, every day.

Eye strain builds over a screen day. Lutein and zeaxanthin build your retina's blue-light filter, and have been studied in screen users for eye strain.†

Eye drops are not enough: dry eye is fuelled by oxidative stress at the surface. Vitamins C and E defend its cells.

Damage to photoreceptor cells accumulates over years. Vitamin E stops the chain of oxidation in their membranes, and C keeps E working.

Night vision is one of the first things to fade when vitamin A runs short. Visor™ supplies it as beta-carotene, made into vitamin A as you need it.

The carotenoids you take build up in your skin, where a trial found a healthier tone. Vitamin C helps your skin make collagen.†
Daily antioxidant protection for screen-heavy eyes: four defences in one formula, and great for your skin too.

Visor™ filters from within. UmbraPlus™ filters light before it reaches your eye: Dark Orange lenses block 97% of high-energy blue light (380–445 nm).
In Visor™:
Other ingredients: slow-release HPMC capsule shell, organic brown rice flour, bamboo silica.
Take Visor™ with a meal. Lutein, zeaxanthin, beta-carotene and vitamin E dissolve in fat, so a meal with a little fat helps you absorb them.
Take them together with a meal, for about 22 mg lutein a day in total.
Visor™ contains beta-carotene. The NHS advises people who smoke, or who have been exposed to asbestos, not to take beta-carotene supplements, so Visor™ isn't suitable if either applies to you. If you're pregnant, breastfeeding, taking medication or under medical supervision, check with your doctor or pharmacist first.

Contains beta-carotene: not suitable if you smoke or have been exposed to asbestos. Food supplements are not a substitute for a varied diet.
That work shows up as four problems: two at the front of your eye, where you feel them, and two at the back, where you don't.
You can't feel the cells you see with, and once lost they aren't replaced. Follow one from 09:00 to 18:00.
The cell that turns light into sight. The cones at the centre of your retina read every word on your screen.
Its power plants run all day and leak a little reactive oxygen as they work. Your eye mops it up. It's work, not damage, yet.
Every day, photoreceptors shed the oldest tenth of their light-catching tips and build new ones. That takes fat, protein, vitamin A and a lot of energy.
Hours on a screen raise reactive oxygen. Researchers measured it at the surface of the eye, on a smartphone:
Over a lifetime
30%
Photoreceptors aren't replaced. By about 70, around 30% of the rods in your central retina are gone.
“The retina ages faster than any other organ in your body.”
A photoreceptor turns light into a nerve signal. Cones read detail and colour; rods work in dim light. In the dark a rod uses about 10⁸ ATP a second, and a cone nearly twice that, and cones keep spending in bright light (Okawa 2008; Ingram 2020).
The retina has one of the highest oxygen consumption rates of any tissue in the body, exceeding the brain (Uddin 2025). Mitochondria leak a small share of their electrons as reactive oxygen, a normal by-product that the eye's defences clear; the retina is one of the body's hotspots of reactive species (Sinha 2020).
Every day the cell layer behind the retina (the retinal pigment epithelium) clears about 10% of the photoreceptors' outer segments, and new discs are added at the base (Bazan 2007; Kevany and Palczewski 2010; Young 1967). The 10% is a rod figure from animal studies. The new discs are built from fats rich in the omega-3 DHA, fresh light-catching protein, and vitamin A, the light-catching part of each rhodopsin molecule; making and clearing this much membrane takes a lot of energy.
The chart is the surface of the eye, not the retina: in a study of 80 healthy young adults, reactive oxygen in the 50 using a smartphone rose 13% after 1 hour and 31% after 4 hours; eyes felt drier and more tired (Choi 2018). No study has yet measured the retina itself across a screen day.
About 30% of the rods in the central retina are lost by about 70 (Curcio 1993). The retina has more mitochondria than any other tissue and ages rapidly (Kam 2023). Photoreceptors are retinal neurons, and the body does not replace neurons lost to degeneration (Sanges 2016).
Each group of nutrients is a targeted system for one of the four problems, and vitamins C, E and B2 work in more than one.
Defend your eye's surface and help it renew.

A screen day works your eyes twice: your focussing muscle holds arm's-length focus for hours, while your retina takes in bright, blue-heavy light all day.
Retina and focussing muscle
Lutein
Zeaxanthin
Bilberry
Lutein and zeaxanthin filter blue light before it reaches the cells you see with. Bilberry is studied for the focussing muscle.
The evidence
In adults on screens at least six hours a day, 24 mg a day of lutein, zeaxanthin and meso-zeaxanthin for six months cut eye strain against placebo, and eyes recovered faster from a bright flash.†
You blink less on screens. The tear film breaks up, reactive oxygen builds at the exposed surface, and inflammation keeps the cycle going.
Front: tear film
Vitamin A
Vitamin B2
Vitamin C
Vitamin E
Vitamins C and E defend the surface that screens dry out. Vitamins A and B2 help it renew.
The evidence
Lutein and zeaxanthin, also in Visor™, help here too: in adults on screens more than six hours a day, 10 mg lutein and 2 mg zeaxanthin a day for six months improved tear production and tear-film stability against placebo.†
Your photoreceptors aren't replaced, yet they're packed with the fat that oxidises most easily. One damaged molecule attacks the next: a chain reaction.
Back: photoreceptors
Vitamin E
Vitamin C
Vitamin B2
Zeaxanthin
Cells you can't replace need more than one antioxidant. E stops the damage spreading, and C restores E.
In dim light, every photon a rod catches reshapes a vitamin A molecule that must be rebuilt. Run short, and night vision is one of the first things to go.
Back: rods
Vitamin A
Vitamin B2
Vitamin A rebuilds the pigment you see with in dim light
The evidence
Lutein has low-light evidence too: in a year-long trial of drivers, 20 mg a day improved contrast and glare sensitivity, especially in low light.†

Clearer® looks after your whole eye. Visor™ adds the antioxidant defence a screen day calls for.
Clearer®
Visor™
The nutrients in Visor™ travel in your blood to every tissue, and your skin, which faces light every day, draws its defences from the same supply.
Vitamin C
Your collagen-making cells depend on vitamin C, and it reaches them through your blood.
Vitamin E
Vitamin E reaches your skin's surface through its oil glands, where it can defend the skin's fats from oxidation.†
Lutein, zeaxanthin and beta-carotene
They settle in your skin: lutein with zeaxanthin improved skin tone in 12 weeks, and carotenoid supplements raised the UV dose needed to redden skin.†
Vitamins A and B2 also help maintain normal skin.
Visor™ defends your retina and tear film. Add care for your vitreous and for the light around you.
Nutrients for the vitreous, where floaters form, and lutein that takes you to about 22 mg a day with Visor™.


Filter blue light before it reaches your eyes, while Visor™ builds the filter inside. Both tints block 100% of UV.

See the UmbraPlus™ pageIf your days are screen-heavy, yes. Visor™ adds vitamin E, B2 and beta-carotene, which Clearer® doesn't contain, and together you get about 22 mg lutein a day, well within international safety assessments.
Not on their own. Lubricating drops soothe dryness for a while, but they don't address oxidative stress in your eye's surface cells. Visor™ works from within: vitamins C and E help protect those cells from oxidative stress, and A and B2 help maintain the membrane. Keep using drops if they help.
Not on their own: breaks rest your focussing muscle, but they don't pause your photoreceptors, which never fully switch off and aren't replaced once they're lost.
In trials, lutein improved contrast in daily computer users within 12 weeks, and six months of lutein and zeaxanthin improved tear production and stability in people on screens all day.†
No, they work at a different point: glasses filter light before it enters your eye, and Visor™ builds the pigment that filters it inside. For both, add UmbraPlus™: Dark Orange lenses block 97% of high-energy blue light (380–445 nm).
Visor™ contains beta-carotene. The NHS advises people who smoke, or who have been exposed to asbestos, not to take beta-carotene supplements, so Visor™ isn't suitable if either applies. If you're pregnant, breastfeeding, taking medication or under medical supervision, check with your doctor or pharmacist first.
