Can You Get Blurry Vision on Keto Diet?
The keto diet is renowned for its ability to produce significant and sustainable weight loss, for the way it balances blood glucose levels and for its ability to reduce cholesterol. Most people who adhere to the ketogenic diet do lose weight and enjoy many other benefits as well.
But a small number of people claim that after switching to a low carb diet they experience blurry vision. While the number of people claiming to experience this is small nothing to do with eyesight should be considered a minor issue. So we decided to take a look at these reports and see if it’s actually possible for the high fat keto diet to produce blurry vision.
The Science Behind Low Carb Diets and Eyesight
It’s long been known that there is a link between blood glucose and eye function. This connection is one reason why so many people with diabetes wind up losing some or all of their sight.
Chronic high blood sugar is one of the most common side effects of poorly controlled diabetes, along with bad breath.
Increased glucose levels act like acid and can cause physical damage to the tiny veins of the retina.
This, in turn, causes the retina to swell which affects both the center of a person's field of vision and their ability to see things clearly. This blurry vision in diabetics is a red flag, so proper diagnosis or treatment should never be postponed. It usually doesn’t take much more than a year for these adverse effects to manifest themselves as a permanent loss of sight.
Keep in mind that we are talking about diabetics here, just to provide an example of the link between high carb diets (which can wreak havoc on blood sugar) and eyesight. One of the great things about the low carb weight loss diet is that it does an outstanding job bringing blood glucose under control. And that is true both for diabetics and those who may have been on their way to developing Type II diabetes if they did not make the switch to the ketogenic diet.

Can the Keto Diet Actually Improve Your Vision?
The keto diet can improve your vision, prevent future eye problems and prevent acute problems from becoming worse, particularly for diabetics. Here are a couple of reasons why the keto diet may actually improve your eyesight:
A lot of the health benefits for your eyes that are available through the keto diet are ones you won't notice. After all, it's difficult to quantify something that doesn’t happen. If you take the keto diet to heart and you don't develop AMD, you'll know what we're talking about.
As Katherine Brooking, MS, RD writes over at webmd.com.
Numerous studies show that what’s most important for long-term weight loss success is adherence, so if you can’t stick with a plan for life, it’s probably not going to give you the results you want.
That goes for the keto diet as well as any other diet plan you adopt for losing weight.
In order to reap the eye-related benefits of the keto weight loss diet, you need to stick to a daily carbohydrate intake of 20 grams and, most importantly, avoid those cheat days that can lead to dangerous blood sugar crashes. If you have any questions or concerns about the effect of the keto diet on your eyes, seek advice, diagnosis or medical advice from your eye care professional.
