5 Reasons Why Eating Too Much Sugar Can Affect Your Vision

Treating yourself a small piece of candy every now and then might be absolutely alright for your health. But what happens if there is too much calories in those treats? Well, eating too many sweets, with its high sugar content, can be harmful to your health. Affecting your endocrine system and your inner digestive colon, these sweets often result in diabetes among adults.

So, before you get frivolous with your sweets, you should also know that eating too much sugar can also affect your eyesight. There have been numerous studies on the correlation of blurry vision and high sugar intake and all of them verify the relation between them.

So, eating too much sugar can result to blurry vision which in turn causes different health problems. What are they? Let’s find out.

1. Diabetes

Diabetes is the most common problem associated with your vision when the sugar content in your blood gets very high. There is a direct link between excess sugar intake and Type 2 Diabetes. In addition to that, the increase of insulin caused by diabetes can also affect your vision as the glucose content in your blood increases. If you have existing myopia or hyperopia, then diabetes can aggravate those conditions, making matters even worse.

2. Retinopathy

According to leading ophthalmologists around the globe, retinopathy is one of leading causes for blindness among diabetic patients. Even diabetic retinopathy is quite common among adults who have high glucose content in their blood. The retina is a highly sensitive part of the eye where the visual signals are interpreted by the brain. Due to high glucose content, the blood vessels around the retina are damaged, which leads to a deterioration in the brain’s ability to transmit visual signals. This, in turn, leads to blindness among patients.

3. Cataracts

Cataracts are usually associated with clouding of the eye lenses which happens quite commonly among elder patients. This clouding of lens hampers the ability of the eye lens to focus light properly, leading to blurry visuals. Cataracts can also be caused by excessive glucose levels in your blood. Why does it happen? Well, the high blood sugar levels lead to the swelling of the eye lenses. This changes the surface of the lens, causing a serious threat for cataracts.

4. Glaucoma

In case of high calorie sweets, there is a serious threat of glaucoma among diabetic patients. What is glaucoma? Well, the condition of buildup of fluids around the eye lenses and the increased pressure due to that is known as glaucoma. With diabetic patients, the glucose levels in their blood causes the blood vessels to become narrow. This leads to the buildup of fluids around the eye socket which cannot be effectively drained. This causes an increase in pressure around the area which is extremely uncomfortable. In addition to that, it also leads to damaged optic fibers as well as a loss of peripheral vision. These cases are found more among adults than children since age plays a huge factor in the deterioration of the nerve endings around the retina.

5. Macular Degeneration

Age related macular degeneration or AMD is directly related to having an excess blood sugar level as well as age. This ailment happens when the macula, which is the central part of the retina, gets damaged. The macula is responsible for obtaining a clearer image on the eye lenses, so a high glucose level can certainly affect the macula and its surrounding nerve endings. Different stages of macular degeneration include signs of dimmed or blurry vision. Excessive deterioration can lead to complete blindness as well.

The lesson that can be learned is the fact that refusing small treats is not the proper way to deal with the problem. However, as with everything in life, there should be a moderating consideration when it comes to sweets and candies as well. Having a high glucose level can make you susceptible to a host of issues that you would not be prepared for. In addition to that, a high blood sugar level will adversely affect other internal systems of your body. Thus, it is much safer to have small treats every now and then, without getting a sugar overload. If you are already diabetic, then it is best to consult your physician so that you can effectively monitor your blood glucose levels.


A traveller by day and reader by night' is how I would sum up my life. My wanderlust led me to quit my cushy job at 28 and finally embark on a journey around the world. Since then, I have lived in many countries and soaked in as many books as possible during my travel journeys. Among them, the "Book of Mirdad" is still my personal favourite and holds a special place in my heart. My progression towards writing was inevitable and happened quite naturally. I have been writing for a few years now an...
