Is Bad Eyesight Hereditary?

Is Bad Eyesight Hereditary?

Numerous features, such as our skin tone, eye color, and hair type, are inherited from our parents. Our genes can also carry on from our parents certain illnesses and diseases, including vision problems. In addition to environmental factors, genetics can play a significant role in determining an individual’s level of vision. While we may not be able to change our genetic makeup, we can live a healthier lifestyle and reduce our risk of developing certain eye conditions.

What Are the Risks of Hereditary Eyesight?

1. Genetic mutations

Hereditary eyesight conditions are often caused by genetic mutations, which can increase the risk of developing eye disorders. 

2. Age-related macular degeneration (AMD)

This condition affects the macula, leading to central vision loss. The risk of developing AMD is higher if there is a family history of the disease. 

3. Glaucoma

Glaucoma is characterized by damage to the optic nerve, resulting in vision loss. Certain genetic factors can increase the risk of developing this condition. 

4. Cataracts

Cataracts occur when the lens of the eye becomes cloudy, leading to blurry vision. There may be a hereditary component to the development of cataracts. 

5. Retinitis pigmentosa

This genetic disorder affects the retina and can lead to progressive vision loss, especially in low-light conditions. 

6. Myopia (nearsightedness)

Myopia is a common refractive error where distant objects appear blurry. It can have a hereditary component, with children of myopic parents being more likely to develop the condition.

7. Hyperopia (farsightedness)

Hyperopia causes close objects to appear blurry. Like myopia, there may be a genetic influence on the development of this refractive error

8. Color blindness

Color blindness is a genetic condition that affects the ability to perceive certain colors. It is more common in males and can be inherited from parents. 

9. Strabismus

Strabismus, or crossed eyes, occurs when the eyes are misaligned. There may be a hereditary predisposition for this condition. 

10. Optic atrophy

Optic atrophy is the degeneration of the optic nerve, leading to vision loss. It can be caused by various genetic factors and is often progressive. 

It is important to remember that having a family history of these conditions does not guarantee that one will develop them. Regular eye exams with an ophthalmologist can help to detect any potential issues early on and allow for appropriate management and treatment.

Environmental Factors That Can Affect Your Eyesight

In addition to genetic influences, environmental factors can also have an impact on an individual’s visual acuity. You can learn more about cataracts, macular degeneration, and cancer in our blog post here. Excessive sun exposure can also cause cataracts. In addition to harming your vision and eye health, smoking increases your risk of blindness by four times when compared to non-smokers.

Treatment for Genetically Poor Vision

Even though you cannot change your genetic makeup, most of the conditions mentioned above are manageable or treatable, particularly if they are detected early. Knowing which conditions are inherited and being aware of your family’s medical history will help you make an informed treatment decision. An annual comprehensive eye exam will help determine the cause of your vision issues and develop a personalized treatment plan for you. Numerous lifestyle choices may reduce overall risk and/or aid in the management of inherited vision disorders.

Maintain Eye Health And Vision

We are unable to change our genetic makeup or how it affects us, but we can take good care of our health to ward off the development of these diseases and conditions that affect the eyes. Maintaining your vision and eye health can be facilitated by eating a nutritious, balanced diet, drinking lots of water, and getting enough sleep. Eating a lot of orange fruit and vegetables (carrots, for example) and fish can help prevent some eye diseases; also, drinking plenty of water can reduce your risk of developing dry eyes.

To find out more about your specific risk of developing eye diseases, please speak with an eye doctor if you’re worried about eye diseases running in your family. Check out our blog for updates on vision and eye health to learn more about maintaining the health of your eyes. Having a routine eye exam once every two years will also enable you to detect any changes in your vision and identify any potential future conditions.
