How Your Vision Changes

As we age, our vision naturally changes. These changes are usually gradual and may not be noticeable at first. However, it's important to be aware of the potential changes that can occur so that you can take steps to protect your eyesight.

Nearsightedness (Myopia)

Nearsightedness is a common vision problem that occurs when the eyeball is too long or the cornea is too curved. This causes light rays to focus in front of the retina instead of on it, resulting in blurry vision for distant objects. Nearsightedness typically begins in childhood and can progress until early adulthood.

Farsightedness (Hyperopia)

Farsightedness is the opposite of nearsightedness and occurs when the eyeball is too short or the cornea is too flat. This causes light rays to focus behind the retina, resulting in blurry vision for close objects. Farsightedness is often present at birth and may become more noticeable as people age.

Astigmatism

Astigmatism is a condition in which the cornea or lens is not perfectly round. This causes light rays to focus at different points on the retina, resulting in blurred or distorted vision at all distances. Astigmatism is often present at birth and may change over time.

Presbyopia

Presbyopia is a condition that affects nearly everyone over the age of 40. It occurs when the lens in the eye becomes less flexible, making it difficult to focus on close objects. Presbyopia is a natural part of aging and cannot be prevented.

Age-related macular degeneration (AMD)

AMD is a leading cause of vision loss in people over the age of 50. It occurs when the macula, the small central part of the retina responsible for sharp central vision, deteriorates. AMD can cause blurred vision, distorted vision, and blind spots.

Cataracts

Cataracts are a clouding of the normally clear lens in the eye. They can cause blurry vision, glare, halos around lights, and decreased color perception. Cataracts are the leading cause of vision loss worldwide and are typically treated with surgery.

Glaucoma

Glaucoma is a group of eye diseases that damage the optic nerve, which carries visual information from the eye to the brain. Glaucoma is often associated with increased pressure inside the eye, but it can also occur with normal eye pressure. Glaucoma can cause peripheral vision loss, blind spots, and eventually complete blindness if left untreated.

It is important to have regular eye exams to detect and treat any vision changes early on. Your eye doctor can recommend the best ways to protect your eyesight and preserve your vision as you age.
