Anatomy of the eye: the building blocks of vision

Our eyes are marvels of biological engineering – intricate organs composed of multiple essential components working in perfect harmony to enable us to see. The cornea, lens, and retina serve as the foundational pillars, orchestrating the complex ballet of light and perception that defines our experience of the world. 

Let’s delve deeper into the fascinating anatomy of the eye, unraveling the intricate web of structures that enable us to see the world around us with clarity and precision. 

Cornea: the window to vision

Imagine the cornea as the transparent gateway to our visual world, positioned at the very front of the eye like a protective dome. This remarkable tissue plays a pivotal role in the initial focusing of light onto the retina, bending and refracting incoming light rays to ensure they converge precisely on the retina’s surface. 

Through its unique curvature and transparency, the cornea acts as our eye’s primary refractive surface, shaping our perception of the world with clarity and sharpness.

Lens: fine-tuning visual precision

Beyond the cornea lies the lens, a flexible and dynamic structure poised to refine and fine-tune the focused light rays onto the retina. Think of the lens as a sophisticated optical instrument, capable of adjusting its shape and curvature to accommodate changes in distance and focus. 

As light passes through the lens, its shape is subtly altered to ensure that objects at varying distances are brought into sharp focus on the retina. This incredible adaptability of the lens allows us to seamlessly shift our gaze from distant vistas to intricate details with effortless precision.

Retina: the light-sensitive canvas

Nestled at the back of the eye lies the retina, a delicate layer of tissue akin to a canvas awaiting the artist’s brushstrokes. Comprising millions of specialized cells known as photoreceptors, the retina serves as the sensory powerhouse responsible for transforming incoming light into electrical signals that can be interpreted by the brain. 

These photoreceptors come in two primary types: 

  • rods, which excel in low-light conditions and facilitate peripheral vision, and
  • cones, which are sensitive to color and detail, enabling us to perceive the rich tapestry of hues that paint our world.

The journey of light: from vision to perception

When light enters the eye, it undergoes a process known as refraction, where it bends as it passes through the cornea and lens to focus onto the retina. This focused light stimulates the photoreceptors in the retina, triggering a cascade of electrical signals that are then transmitted along the optic nerve to the brain. 

It’s here that the magic happens; the brain interprets these signals to create the visual images that we perceive. Once the electrical impulses reach the brain’s visual cortex, they are interpreted, allowing us to become consciously aware of what we see. This process transforms the raw data received from the eyes into the vivid images and scenes that we perceive, shaping our understanding of the world around us. 

It’s through this coordination between our eyes and brain that the journey of light becomes the foundation of our perception, highlighting the incredible capabilities of the human eye.

Understanding vision issues: how daysoft can help

Despite our eyes’ accomplishments, vision issues can still arise. Common problems such as nearsightedness, farsightedness, and astigmatism can impact our ability to see clearly. Sensitive eyes, allergies and hayfever mean dryness can create issues for contact lens wearers, too. 

daysoft’s daily disposable contact lenses are designed to address these issues and provide you with clear, comfortable vision. Our lenses are meticulously manufactured to correct refractive errors and provide optimal visual acuity, allowing you to see the world with clarity and confidence. 

Whether you’re working at a computer, driving, playing sport or simply enjoying life’s everyday moments, daysoft lenses are designed to support your eye health and enhance your vision. Here’s how we do it:

Comfortable to wear

We’ve developed a unique contact lens edge design that provides you with all-day comfort. We call it Soft-Edge™

Unlike the conventional chiselled-edge or stepped-edge shapes you’ll find on many other hydrogel lenses, daysoft lenses have a smooth, continuous edge. This allows your eyelid to glide smoothly over the lens edge. 

Easy to insert

daysoft daily disposable lenses are super-easy to put in. Even though they’re ultra-thin, our lenses are always located in the blister pack in the same way. This means they’re never folded, thanks to our innovative INPAC technology. All you need to do is ‘scoop’ them onto the soft tip of your finger for confident handling and easy onto-eye insertion, every time.


daysoft® lenses are 58% water and our lens material is very pliable. Added to our Soft-Edge™ design, this means exceptional wearing comfort – and not a dry eye in the house.


We want to give you options. Our daily disposable contact lenses are available in Classic or Silk (for those who have sensitive, dry eyes or suffer from allergies) solutions.

Plus, every purchase is backed by our no-quibble returns policy, so you can try daysoft® lenses hassle free. If you aren't happy with your purchase, we'll refund you.
