A lot of people who have had great eyesight for their entire life are surprised when they suddenly find it difficult to see things close up and feel as if they need reading glasses. Slow physiological changes in the eye start at around the age of 20, and the lens of the eye – which helps us to clearly see different objects at different distances – slowly starts to lose its elasticity.
The lens is inside the eye, and by changing its shape with the help of tiny muscles, this also changes the way that light refracts onto the back of the eye, where the clear image is sent to the brain. The effects of this process are not perceptible at first, but by the age of 40 a lot of people feel as if their “arms have become too short”. A breaking point where the eye is no longer able to shape the lens enough to provide clear vision has then been reached.
Presbyopia or changes in eyesight due to age manifests itself in the loss of the ability to see close up after turning 40. In the beginning this may only occur when the eyes are tired in the evening, or in low light, or be felt in the slowness of changing focus at different distances, for example when looking far away and then close up. Another symptom may be headaches caused by eye strain.
Changes take place in everyone’s eyes whether or not a person has worn glasses before. The loss of clarity that comes with age cannot be prevented by eye exercises or in any other way. The most noticeable changes in the elasticity of the lens of the eye take place at the age of 50 when the prescription strength changes more rapidly; this process usually stops by the age of 60. What should be done?
It is recommended to have eye examinations once a year. Presbyopia is corrected with glasses and contact lenses. It is possible to use reading glasses, reading glasses with an extended viewing distance, bifocals, office work glasses or progressive glasses depending on where and what purpose glasses are needed for. There are also contact lens solutions: progressive contact lenses or monovision with regular contacts (one eye being corrected to see far away and the other one to see up close). We advise consulting an optometrist to find the most suitable solution for you.
People who have never worn glasses before may find wearing them strange and unusual at first. But clear vision will improve the quality of your life noticeably and you will soon realise that in addition to glasses being an everyday item, they are also an irreplaceable accessory. Our optometrists and customer consultants will advise you on your choice of frames.
