The danger of sugar and eye problems. In this video, I break down how sugar affects your eyes, how blood sugar affects the body, and why chronically elevated blood sugar — especially in diabetes mellitus — can quietly lead to serious diabetic eye problems.

We hear a lot online about how sugar affects the body, obesity, inflammation, and overall health… but very few people talk about sugar and eye problems.

In this video we cover:

• Why high blood sugar blurry vision happens (lens swelling + prescription shifts)
• How diabetes and the eye are connected through cataract formation
• What causes diabetic retinopathy and macular edema
• Why some people see new floaters from vitreous hemorrhage
• How abnormal blood vessels (neovascularization) develop
• When advanced diabetic eye problems can lead to retinal detachment and vision loss
• The link between diabetes and dry eye disease
• Increased risk of infection, styes, and corneal ulcers
• How nerve damage can lead to neurotrophic keratitis
• Why some patients develop double vision due to ischemic nerve damage

If you’ve ever wondered:

– How diabetes affects the eyes
– What happens during a diabetic eye exam
– How sugar and your health are connected to vision
– Are carbs bad for you?

This video will help you understand the science behind diabetes, optometry, ophthalmology, and eye health.

⚠️ Important: This is NOT about saying “carbs are bad” or that sugar must be eliminated entirely. Carbs and sugar can absolutely be part of a balanced diet. But chronically elevated blood sugar levels — especially in uncontrolled diabetes — significantly increase the risk of long-term eye health complications.

If you’re experiencing blurred vision, floaters, distorted central vision, or double vision — do not ignore it. Schedule a diabetic eye exam or comprehensive exam with your local eye doctor.

Your eyesight is one of your greatest gifts. Let’s protect it.
