What is low vision? Symptoms and Treatment

Low Vision is a vision loss that cannot be corrected with prescription glasses, contact lenses, drugs, or surgery.

According to the WHO, low vision occurs in those people who have a visual acuity equal to or less than 0.3 (30% vision) and the loss affects both eyes. Low vision has no cure, since it derives from a visual impairment that generates a loss of the patient’s visual capacity.

It is estimated that in Spain there are 1.8 million people affected by low vision. A problem that occurs for different social causes and other factors such as age or congenital diseases.

Causes of low vision

Usually the process of vision loss, in developed countries like Spain, occurs in older people. However, there are different pathologies that can precipitate vision problems such as:

  • Macular degeneration due to age
  • Cataracts in the eye
  • High myopia
  • Glaucoma 
  • Diabetes
  • Retinal detachment
  • Congenital diseases

Symptoms, how to detect low vision?

People who suffer from vision problems can detect different symptoms that cause visual difficulties and reduce their quality of life.

There is no single way of low vision, single or several symptoms can be detected at the same time such as:

  • Tired sight
  • Blurry vision
  • Difficulty reading
  • Difficulty driving
  • Difficulty recognizing faces
  • Color alteration

All these symptoms produce a loss of visual capacity that reduces our autonomy and ability to carry out our routine tasks. In addition, visual impairment is closely related to emotional and social problems derived from low vision (impaired self-esteem, depression, anxiety, loneliness, financial difficulties, and relationships with loved ones).

Low vision treatments

Although low vision is not considered a disease with a possible cure, there are some solutions on the market to improve the visual capacity of people who suffer from visual loss.

For example, some specialist ophthalmologists help people with low vision with techniques to relearn to read or write, and also advise them on other ways to carry out their daily tasks. Visual rehabilitation techniques have advanced in recent years, so that a person suffering from low vision can gain quality of life despite their new visual condition.

On the other hand, there are objects that help people with visual impairment, such as filters and special magnifying glasses to improve low vision.

What can help me in my day to day if I suffer from low vision?

At Salas Ópticos we have filters and glasses that help to:

  • Visualize the surrounding objects magnified
  • Reduce field sight distances
  • Increase the contrast
  • Color redefinition
  • Increase in general luminosity
  • Focal illumination
  • Glare control

Also, there are some techniques that can be applied at home to improve your day-to-day vision such as increasing the amount of light in your home with more powerful light bulbs. You can also dim the lamps to protect yourself from glare and look for writing tools creating greater contrasts like a white background and thick black marker.

Even so, if you suffer from low vision, you should not give up a good quality of life. There are many people who currently suffer from visual impairment, and out of shame, they do not go to a specialist.
