A change in vision as you age is often normal, but for some people, a decline in vision with age is a cause for concern. What sets apart a normal occurrence from a more concerning one can vary, so it is best to speak with an optometrist about any concerns you have. However, there are some worrying indicators you do not want to ignore.

Tunnel Vision

The human eye is equipped with a helpful function known as peripheral vision, which provides you with a clear view of your front, as well as your sides. Your peripheral vision should not decline as you age. When it does, it is known as tunnel vision, as it mimics the limiting view you experience when looking through a tunnel. 

This vision change is often a sign of advanced glaucoma, which is a condition that results when there is an excessive amount of pressure around the inside of the eye. There are treatment options for this disease, but if left untreated, blindness can result.

Cloudy Vision

Another change in vision with age that should not be perceived as normal is cloudy vision. This vision change makes it appear as though you are looking through a fog or haze, which can hinder your ability to see significantly. One concern that can prompt this type of vision change is cataracts.

Cataracts are a condition that causes the lens of the eye to cloud, which in turn, causes your vision to appear cloudy. In addition to age, diabetes and a history of smoking can increase the threat of developing this condition. Cataracts can also alter the appearance of your eye, so should you notice any issues, be sure to have an exam.

Discomfort-Driven Decline

Vision changes that are prompted by eye discomfort are also worth addressing. With age, the tear ducts can stop working as efficiently. Since these ducts are responsible for keeping the eyes lubricated, dry eyes can become a problem. Dry eyes not only cause discomfort and irritation, but they can lead to vision concerns. 

In some cases, dry eyes can lead to blurred vision and sensitivity to light. In severe cases, it can even lead to damage along the surface of the eye that might also impact your vision. There are a variety of prescription medications available to treat this condition.

If you have concerns about vision changes, schedule an exam with an optometrist to find the source of the problem.
