Eye tests are about more than vision. In fact, an eye test can help detect over a hundred different medical conditions from diabetes to heart disease.

Learn how to manage screen time

Life demands a lot from our eyes, and working on digital screens for long periods of time can lead to Digital Eye Strain (DES), or Computer Vision Syndrome (CVS).

Help protect your eyes from the harmful UV radiation

Eyes are just as vulnerable to UV rays as your skin. That's why knowing ways to protect them, like with UV blocking# in your contact lenses, is so important.

Eat eye-healthy foods+

Certain foods can support your eye health+ now and even help prevent vision damage later in life, reducing your risk of serious chronic eye conditions like cataracts or macular degeneration. Include foods with these key vitamins and nutrients in your diet:

Lutein & Zeaxanthin

These nutrients may reduce the risk of eye diseases like cataracts and can be found in kale, spinach, broccoli, asparagus, raspberries, papaya, peaches, and mangoes.

Vitamin C

This vitamin may lower your risk of developing cataracts, and when taken with other nutrients, it may slow the progression of age-related macular degeneration and visual acuity loss. Vitamin C can be found in oranges, grapefruits, kiwi, strawberries, tomatoes, broccoli, and red and green peppers.

Vitamin E

This vitamin helps protect your eyes and can be found in almonds, sunflower seeds, vegetable oils, avocadoes, wheat germ, and sweet potatoes.

Essential fatty acids

Omega-3 fatty acids help with visual development and retinal function and can help reduce inflammation and enhance tear production. Sources of essential fatty acids include fish such as salmon and tuna.

Zinc

Beans and lentils, seeds, meat/seafood, dairy, and eggs are all sources of zinc, which helps bring vitamin A to the retina to help produce a protective pigment in the eyes.

Video conferencing, emails, spreadsheets—as work has become more digital, it's especially important to take care of your eyes.

What should I learn next?

Now that you know the basics of how to keep your eyes healthy, it can be helpful to be proactive and learn not only about the anatomy of the eye itself, but also vision issues and eye conditions to look out for over your lifetime.

The anatomy of the eye

Your eyes receive light and transmit detailed messages to your brain, which interprets them as images. Each part of your eye has a different specialised role in transmitting these images.

Images are for illustrative purposes only and may not be anatomically accurate.

Cornea

At the front is the cornea, a transparent window which allows light to travel into your eye.

An illustration showing where the sclera is in the eye

Sclera

The sclera is the tough, protective ‘white of your eye’, which is opaque.

An illustration showing where the conjunctiva is in the eye

Conjunctiva

Around the cornea, a thin, clear membrane called the conjunctiva helps to protect the rest of the front of your eye and the inside of your eyelids.

An illustration showing where the iris is in the eye

Iris

Gives eyes their colour and is expanded or contracted with tiny muscles to manage incoming light through the pupil.

An illustration showing where the pupil is in the eye

Pupil

The small, black spot in the center of the iris, which allows light to enter the eye.

An illustration showing where the lens is in the eye

Lens

The flexible and transparent tissue behind the iris and pupil that focuses light on the retina.

An illustration showing where the aqueous humor is in the eye

Aqueous Humor & Vitreous Humor

The cavity between your lens and cornea contains a liquid called Aqueous Humour. A jelly-like substance, called Vitreous Humour, fills the cavity behind your lens. The Aqueous and Vitreous Humours help to give your eyes their shape.

An illustration showing where the retina is in the eye

Retina

Your retina’s job is to capture light information that the main nerve in your eye (your optic nerve) sends as nerve impulses to your brain. Your brain then translates these messages into images. On your retina, two types of light-sensitive cells – rods and cones – capture light rays. Rods help you to see in dim light, whilst cones enable you to see detail and colour.

An illustration showing where the macula is in the eye

Macula

The area in the center of retina, made up of a high concentration of cones, provides highly detailed vision.

Do not wear contact lenses if you have an eye infection, any eye disease or systemic disease, that may affect the eye, or if you are allergic to any ingredients. If you experience eye discomfort, excessive tearing, vision changes, redness or other eye problems, remove the lens and contact your Eye Care Professional immediately.
