Common Causes of Vision Decline
- Posted on: Dec 17 2010
Treatment for poor vision is a necessity for many Americans, but the specific causes of vision decline can vary. According to the National Institute of Health, the following conditions are frequently responsible for vision changes. Some of these problems develop with age while others can appear at any stage of life.
- Presbyopia – this is a common eye condition that appears in individuals over 40. It’s characterized by the inability to focus on close objects, and can lead many to turn to reading glasses. Other treatment options can address vision decline from Presbyopia.
- Cataracts – this issue surfaces most often in the elderly when the lens of the eye becomes cloudy. It can affect vision greatly, causing blurred vision, halos, bad vision at night and ultimately, poor vision during the day.
- Glaucoma – this is a condition where there is increased pressure in the eye, and it can be severe enough to cause blindness gradually or very quickly.
- Macular degeneration – this condition involves a loss of central vision. In particular, it causes blurred and distorted vision of things viewed up close. This is an issue that typically appears with age and it happens after 40. However, it can also cause blindness and is the leading cause in people over the age of 60.
- Retinal detachment – this vision issue is self-explanatory but is characterized by a curtain over vision, floaters or random flashes of light.
- Optic neuritis – inflammation of the optic nerve.
