Vision requires light to pass through the eye’s pupil then through the lens which focusses the light onto the back layer of the eye, the retina. When this lens inside the eye becomes cloudy, it is called a cataract. The more cloudy the lens becomes the more foggy your vision will be. The major contributing factors to cataract formation is older age and damage caused over your lifetime from UV exposure.
Cataracts are one of the most common causes of vision loss, but are treatable with cataract surgery to remove the cloudy natural lens and replace it with a clear artificial implant. There are no medications or eye drops that will make the cataract go away; surgery is the only treatment. Cataract surgery is only required when the vision loss impacts your daily lifestyle.
If you are noticing any problems with your vision, make an appointment with your eye care professional.
