You can put too much pressure on your eyes' blood vessels by carrying more weight. Poor vision can result from damage to these vessels, which are so delicate. You are more likely to develop some of the eye diseases that are linked to obesity if your BMI (body mass index) is higher. Gaining weight can potentially affect your eyesight in several ways. Here are a few examples:
Increased risk of diabetes: Being overweight or obese can increase your risk of developing type 2 diabetes, which can lead to vision loss or blindness. High blood sugar levels caused by diabetes can damage the small blood vessels in the retina, the light-sensitive tissue at the back of the eye, leading to a condition called diabetic retinopathy.
Increased risk of glaucoma: Glaucoma is a group of eye conditions that can lead to vision loss or blindness. It is caused by increased pressure within the eye. Obesity has been proposed to be a risk factor for developing glaucoma.
Increased risk of cataracts: Cataracts are cloudy areas in the lens of the eye that can cause vision loss or blindness. Obesity may contribute to the development of cataracts.
Increased risk of age-related macular degeneration (AMD): AMD is a condition that affects the macula, the part of the retina responsible for central vision. It can cause vision loss or blindness. Obesity may lead to the development of AMD.
It is important to maintain a healthy weight and follow a healthy lifestyle, including eating a balanced diet and getting regular exercise, to help reduce the risk of developing these and other health conditions that can affect your eyesight. If you are concerned about your weight or your eye health, it is a good idea to speak with a healthcare provider for guidance and advice.
