Types of visual impairment

The visual disability is, unfortunately, quite common. When we hear about it, the first thing we think about is blindness, which is the total or almost total lack of vision. But there are many different types of visual impairment, each with its particularities, with its symptoms and with its way of developing. Of each of them, however, it is possible to cope with a normal life with the appropriate help and support from the people surrounding the affected person, as if they were locksmiths helping them to open the door apparently closed by disability. Here we will see some examples of these conditions.


This condition produces a tunnel vision, in which the peripheral vision diminishes with time. The “hoop” of vision, gradually becomes smaller and smaller until the affected loses completely the ability to see clearly in the full extent of their field of vision. It is, as we see, a degenerative condition that, however, has treatment if it is attended to in the first stages of its appearance. It is important, therefore, to be always aware of all the signs and the way in which the vision can be affected over the years.

Macular degeneration

This type of degeneration of the sense of sight is one of the most common since it is what occurs with age. The process is inverse to what we have observed with glaucoma, since peripheral vision remains and what begins to distort over time is the vision towards the center of the visual field. This greatly affects the performance of activities that require the concentration of sight, such as reading, manual activities, etc. Although it is a condition that occurs without pain, it is quite common, so it is recommended to perform periodic eye exams when you reach a certain age.
Its name comes from the visual sensation that this condition produces in the person who suffers it. It is as if his vision is permanently distorted by a fall of water. This can greatly blur the vision or even make it almost completely lost. This condition can be accompanied by an excess of sensitivity to light and is quite common from a certain age, so, as in all cases, it is recommended to make continuous checks.

Diabetic retinopathy

This condition of the sense of sight is related to diabetes. The damage produced by this disease to the circulatory system can affect the sight, producing reduction in visual acuity, headaches or black spots in the visual field. It is degenerative and can lead to loss if it remains untreated.
As we have seen, in most of these and other conditions, one of the most important things is to always be attentive to the symptoms to seek help as quickly as possible. Only then we will be able to stop the deterioration of the sight that comes with them and thus we will be able to enjoy many more years of quality of life.
