Diabetes & Your Eyes

Today we are raising awareness of a condition that affects millions of people around the world and one of the most common causes of blindness. But did you know this can be prevented and/or treated when early diagnosed and with regular eye health check-ups?


What is Diabetes exactly?

Diabetes is a chronic (long-lasting) health condition in which the body does not properly process food to use as energy. Most of the food that we eat is turned into glucose (sugar) and released into the bloodstream, for our bodies to use as energy. The pancreas then, creates a hormone called insulin to help the glucose reach the cells in our bodies. People who suffer from diabetes cannot produce enough insulin or cannot use their own insulin as well as it should, leading to an increase of glucose (sugar) in your bloodstream. There are 2 types of diabetes:

- Type 1 Diabetes : The patient's immune system attacks and destroys the cells that produce insulin. It requires daily administration of artificial insulin by injection or insulin pump;

- Type 2 Diabetes : The patient’s body does not produce enough insulin or the body’s cells do not react to it. Usually managed with a combination of a healthy controlled diet and medication (tablets). This type is far more common than type 1.

There is also a type of diabetes that develops during pregnancy for some women called gestational diabetes. This happens because their bodies are unable to produce enough insulin to absorb all the glucose. This type usually disappears once the baby is born.


4.7 million of people in the UK have Diabetes, 90% of those being Type 2 diabetics. According to statistics provided by the www.diabetes.org.uk 1 in 10 people over 40’s has now type 2 diabetes.


How does Diabetes affect my eyes?

Diabetes is the leading cause of preventable sight loss in the UK. Diabetes can affect your eyes in many ways and in some cases when left untreated, these complications might even lead to blindness. The most common complication is Diabetic Retinopathy .

Diabetic Retinopathy is a eye disease caused by high levels of glucose (sugar) and blood pressure in your eyes, sometimes causing serious damage in your eyes. When the blood vessels in your eyes are damaged, they can get blocked, leak or grow randomly, meaning the retina won’t get the blood it needs to work properly, and consequent you vision will also be affected.

There are 3 types of Diabetic Retinopathy :

- Stage 1 - Background Retinopathy : Tiny bulges develop in the blood vessels, that may cause slight bleeding, but usually it does not affect your vision. Even though your vision is not yet affected, you will need to prevent the problem from getting worse;

- Stage 2 – Non-proliferative Retinopathy : More severe and extensive changes affect the blood vessels, including more significant bleeding into the patient's eye. The damage is more serious than Stage 1 and will require your eyes to be checked and screened more often;

- Stage 3 – Proliferative Retinopathy : Scar tissue to the eye cells and development of new blood vessels, which are weak and bleed easily. This means you are now at very high risk of losing your sight.

There is also Diabetic Maculopathy which affects the middle of the eye, meaning you won’t be able to read or drive.


How to prevent Diabetic Retinopathy?

It is possible for most people to reduce the risk of developing Diabetic Retinopathy or preventing it from getting worse, by:

- Getting your eyes screened regularly;

- Spotting changes in your eyesight;

- Keeping your blood sugar levels, blood pressure and cholesterol in control;

- Taking your diabetes medication as prescribed;

- Having a balanced & healthy diet;

- Exercising and hydrating.


Changes to look out for:

- Floaters – if you start seeing what looks like wispy clouds, small black spots or little threads floating in and out of your vision;

- Dimmer Vision – when your vision looks darker, like you are wearing sunglasses all the time;

- Struggling to see in the dark .


Diabetic Eye Screening

Any person with diabetes >15 should be offered a screening once a year, or as often as the Optometrist advises. Screening should be done for the following reasons:

- Diabetic Retinopathy doesn’t show any symptoms in the earlier stages;

- The condition can cause permanent blindness if not diagnosed and treated promptly;

- Screening can detect problems in your eye before they start to affect your vision;

- When caught early, treatment can help prevent or reduce the chances of vision loss.


If you are diabetic and due for an eye test or you have any of the above symptoms described above, please make sure to book an eye check-up as soon as possible. At Care Optics we have specialists in Diabetic Retinopathy, so you will be in excellent hands. You can book that appointment over the phone or email and our staff will make sure to take precise details so you can have the best treatment according to your symptoms.

At Care Optics - Eye Care, We Care

Welcome to Care Optics , your trusted independent opticians serving Woodford and Dagenham . Our mission is to provide complete care , and that commitment to your total sensory health is never more critical than when you’re behind the wheel. As the weather cools and the clocks roll back, the visual demands of driving in East London and Essex skyrocket. Early darkness, heavy rain, and the blinding glare of oncoming headlights create a challenging environment where safety relies on fast reactions and perfect clarity. This year, leading into Road Safety Week in November , we are not just focused on your sight; we are championing the combined power of your senses to ensure you have maximum situational awareness and safety on every journey. This vital national campaign encourages all drivers to proactively check their readiness, and at Care Optics, that means ensuring you "See Clearly, Drive Safely." The Sensory Challenge: Why Driving Demands More Than Standard Lenses Driving is the most visually demanding task many of us perform daily. When light levels drop, our eyes must contend with Mesopic Vision (low-light vision), which severely impacts our ability to process contrast, depth, and colour. The Seasonal Hazards We Must Mitigate: Dazzling Glare: The intense, focused beams of modern LED and Xenon headlights can cause severe glare at night, resulting in temporary blinding and delayed recovery time for the eye. During the day, low-angle winter sun is equally disruptive, reflecting off wet roads and traffic. Visual Fatigue: Extended night driving or driving through rain requires sustained, intense visual concentration. This rapidly leads to eye strain, headaches, and overall driver fatigue, significantly increasing the risk of making an error. Tunnel Vision: At higher speeds or in stressful situations, your peripheral vision naturally narrows. Any compromise to your central or peripheral sight—whether from an outdated prescription or inadequate lenses—puts you, your passengers, and others at risk. The Care Optics Solution: Precision Through Our On-Site Lab At Care Optics, we believe the best driving lenses should be ready when you need them, offering uncompromised visual accuracy and quick turnaround. This is why our Dagenham branch is home to on-site lab facilities —a key differentiator that ensures the highest quality results, rapidly. The Lab Advantage for Driving Lenses: Ultimate Lens Precision: Unlike practices that rely solely on external labs, our skilled technicians work directly with your optometrist’s prescription. This direct collaboration ensures your driving lenses—especially complex progressive lenses or those with specific coatings—are crafted and finished with the highest degree of accuracy, perfectly centered for your driving posture. Rapid Service and Fitting: We understand that you need your safety equipment quickly. The on-site lab dramatically cuts down waiting times for new lenses and enables rapid adjustments or emergency repairs. You get maximum visual safety sooner. The Power of Anti-Reflection Coatings: The single most crucial feature for night driving is an advanced Anti-Reflection (AR) coating. We expertly apply and verify the quality of AR coatings that virtually eliminate the internal reflections within the lens and significantly cut the harsh starburst effect from oncoming lights, giving you crisp, clear vision at all hours. Complete Sensory Safety: The Role of Hearing in Driving As providers of comprehensive Hearing Care Services at both our Woodford and Dagenham practices, we recognise that driver safety is a dual-sensory effort. When you are driving, your auditory system is your primary early warning system, backing up your vision: Hearing Warning Signals: Your ears alert you to hazards outside your direct line of sight—an ambulance siren, a train horn, the sudden sound of a vehicle braking, or a developing mechanical fault in your own car. Even a minor, undiagnosed hearing loss can delay your reaction to these critical sounds. Processing Road Noise: Healthy hearing allows you to monitor subtle changes in road conditions, such as the sound of tires losing grip on ice or water. Your brain uses these auditory cues to complement the visual information it receives, enabling faster, more accurate responses. We encourage all drivers to incorporate a Hearing Health Check with their Comprehensive Eye Examination. By protecting both your sight and your hearing, you maximise your situational awareness and significantly reduce your risk on the road. Your Driving Vision Checklist with Care Optics Whether you visit our Woodford branch for our community expertise or our Dagenham branch for the speed of our on-site lab, we offer the complete solution for safer driving this winter. Book Your Comprehensive Eye Examination: Ensure your prescription is optimized for the distance and the low-light conditions required for driving. Prioritise AR Coatings: Discuss the latest anti-glare technology with our dispensing team. Investing in a high-quality AR coating is essential for comfortable and safe night driving. Consider Polarised Lenses: For tackling low winter sun glare and reflections off wet roads during the day, a dedicated pair of prescription polarized sunglasses is non-negotiable. Check Your Hearing: Ask about our complimentary Hearing Health Checks to ensure your complete sensory system is ready to face the challenges of winter driving. With a team that boasts over 80 years of combined experience (Woodford) and the benefit of on-site lab facilities (Dagenham), Care Optics is your independent partner committed to keeping you and your family safe and clear-sighted across East London and Essex this winter. Drive Safer. See Better. Hear Clearly. Book with Care Optics Today!  Contact your local branch to book your comprehensive sight test and discuss your driving lens needs.

Children may not always realise they have a vision problem. They assume everyone sees the way they do, which is why early detection is key and an early diagnosis will not just help your child's vision long term, but will also help them develop.
