What format is the guide in?

A PDF, emailed to you. It reads well on a phone, a tablet or a laptop, and it prints cleanly if you would rather have it on paper. There is no app, no login, and nothing that expires.

How is this different from the free guide?

The free guide is five pages covering five habits. This one is the full argument: what changes in the eye and why, the whole nutrition picture including where the evidence goes against the popular answer, light and screens, the systemic factors, what an examination involves, and a 90-day plan. If the free one answered your question, you do not need this one.

Is it medical advice?

No. It is education, written to the same standard as the articles on this site, and it says throughout that it does not replace an examination by an eye-care professional. If your vision has changed, book an appointment rather than reading a PDF.

It is published by fovea.bio and written from the primary literature and the guidance of the major ophthalmology bodies, each named in the sources. We do not put an invented author or invented credentials on anything, here or anywhere else on the site.

By email for now, while this is small. You write to us, we send payment details and the guide. We would rather tell you that than build a checkout that pretends to be a shop.

What if it is not useful to me?

Reply to the email and we will refund you. There is no form and no window to argue about. A guide that has to keep your money to be worth writing is not worth writing.

The complete guide

Protect your vision
after 50.

Everything on this site, argued through in order, with the nutrition evidence set out honestly and a plan at the end. It covers what actually changes in the ageing eye, which of the popular fixes survive a look at the trials, and the systemic factors that quietly do most of the damage.

Written to the same standard as the free articles, which means it tells you where the evidence says no. There is a chapter on blue light whose conclusion is that it mostly does not matter, and a supplement section that spends as long on who was not helped as on who was.

Around 4,200 words, laid out to be read in one sitting or kept as a reference.
A 90-day plan that sequences the changes rather than listing all of them at once.
A printable one-page checklist for the fridge door.
Questions to take to your next appointment, written to be read out.

What is in it

Six chapters, in the order the argument runs. The last one is the only part that asks anything of you.

What actually changes after 50

The lens stiffening and near focus fading. The macula ageing and the risk curve that comes with it. Cataract. The tear film thinning. And the two quiet ones, glaucoma and retinopathy, which take vision without symptoms until late.

Eat for your eyes

The two pigments the macula is physically built from and where they come from. Omega-3s and the tear film, including the large trial that found against them. Then the honest section on supplements: who the AREDS2 formulation was tested in, and who it did nothing for.

Light, screens and reading

Ultraviolet, which genuinely counts and has a straightforward answer. Blue light, where the hype outran the science and a Cochrane review of seventeen trials found close to nothing. Then the desk setup that actually reduces strain, which is about blinking and geometry.

The whole-body levers

Smoking, which is the strongest single modifiable factor and not a close contest. Blood sugar. Blood pressure. Sleep and movement. This is the chapter people skip and the one with the largest effect sizes in it.

The exam, your numbers and the red flags

What a comprehensive dilated examination actually includes and why the drops matter. How often to go, by age and risk. The questions worth asking while you are in the chair. The symptoms that mean today rather than next month.

Your 90-day plan and printable checklist

The whole guide reduced to something you can actually do, sequenced over three months, with a one-page checklist at the end designed to be printed and stuck somewhere you will see it.

What you get

Around 4,200 words, laid out to be read in one sitting or kept as a reference.
A 90-day plan that sequences the changes rather than listing all of them at once.
A printable one-page checklist for the fridge door.
Questions to take to your next appointment, written to be read out.
Every claim sourced, with the further reading listed at the end.
A PDF you own. No app, no login, no subscription, no expiry.

Who should not buy this

A site that tells you when a supplement does nothing has to be willing to tell you when its own product is not for you. Four cases where it is not.

You want your eyesight sharpened: It will not do that and nor will anything else. Refractive error comes from the physical shape of the eye. This guide is about lowering the risk of losing the sight you have, which is a different and more achievable goal.
You already read everything on this site: Then you have most of it. The guide is the same evidence organised into a sequence with a plan attached, which is worth something, but it is not new research and we are not going to pretend it is.
You want to know what is wrong with your eyes: No document can tell you that. If your vision has changed, the useful next step is an appointment, and the guide will say the same thing at greater length.
The free guide is enough for you: For a lot of people it genuinely is. It covers five habits with the reasoning behind each. Take it, and come back only if you want the full argument.
