Wear glasses or not, to keep your visual system in shape follow the following tips:Eating habits are very important to take care of our visual health. A healthy diet with the presence of vitamins (A, C, E …) and antioxidant elements has many benefits for eye health.
Eye hygiene is also very important. You should not touch or rub your eyes with your hands, since you could expose them to infections.
It is imperative that you protect your eyes from the sun with approved sunglasses, which you can find in your view of confidence .
We must avoid unnecessary efforts in our sight. Not carrying the correct optical correction force our eye to an extra effort that is harmful.
Little sleep makes the eye does not recover well from the aggressions of the day. During the night there is a regeneration of the epithelial cells that cover the anterior face of the eye.
It is very important to illuminate the object that we are looking at (a book, a mobile, the TV, etc), but without reflections and without the light directly affecting our eyes.
We must maintain an adequate distance with the objects we are looking at . The TV to at least 2 meters and when we go to read or write try to be about 35-40 cms.
Protect your eyes with homologated sunglasses .Do not get too close to reading or writing, or tilting or turning your head or back.
When doing tasks close up you must take care of the lighting of the surroundings.
Do not read or study when you are too tired or about to fall asleep. Do not read or study as soon as you wake up in the morning, wait at least an hour for the eye to adapt.
Do not watch TV at a distance of less than 2 meters and make sure you maintain good posture. You must have the room lit, never in the dark.
When you go by car avoid reading or other activities from close up, it is preferable to look from afar.
Place the monitor and keyboard aligned right in front of you.
Place the screen about 50 cm apart and slightly below eye level.
Reduce the brightness to a minimum and position the screen so that there are no reflections.
Adjust the font size of the screen to one that you find easy to read.
Wipe dust off your computer screen to increase sharpness.
Keep your back and neck straight, your feet flat on the floor and your elbows bent at a 90 degree angle.
Try to rest for 2 to 3 minutes every 15 to 20 minutes. Use to stretch your arms, legs and back.
If you wear glasses with anti-reflective treatment, you will reduce glare and increase visual comfort.
Take advantage of breaks to perform other tasks that do not involve the use of the computer.
Submit to eye checks at least once a year. Especially from the age of 40 and if there is a history of pathologies related to the eyes.
WHAT IS PRESBYOPIA?
“Presbyopia or tired sight is a visual difficulty that appears over the years and causes problems when focusing on nearby objects.”
The lens, a natural lens of the eye, makes the effort necessary to see closely. This effort, known as an ” accommodation reflex, ” becomes more difficult over the years, and as a consequence, objects in the near vision look worse .
Symptoms of Presbyopia
Extend your arms or lift your glasses so you do not see blur
Visual fatigue and headache when reading closely
Itching or stinging eyes working with the computer
Difficulty reading small print
Far blurry objects
Presbyopia is not a disease, it is a natural evolution of sight from the age of 40-45 years.
IS PREVENTING TIRED SIGHT POSSIBLE?
The tired sight is an inevitable consequence of the passage of the years, a natural evolution of vision and, therefore, can not be prevented. All people end up having presbyopia sooner or later, although the most frequent one is that it manifests from the 40-45 years.
Although tired sight can not
be prevented, it is possible to correct its effects with different methods. The most common: ophthalmic lenses.
Astigmatism is an error in the visual approach because the cornea, rather than being spherical, is slightly oval. This refractive error is described in function of the difference of curvatures and the orientation or axis of the same. People who have astigmatism may have trouble seeing from near and far . Astigmata are usually myopic and / or hyperopic. An astigmata may have visual problems similar to those experienced by a presbyopic. But, it should be noted that while astigmatism is determined by the genetic morphology of the eye, presbyopia is due to stiffness of the lens, caused by the passage of time .
WHAT IS THE DIFFERENCE BETWEEN PRESBYOPIA AND MYOPIA?
The myopia or refractive error is a mistake in the visual approach which occurs when the distance between the cornea and the retina is too long. Thus, the image perceived by the eyes is “formed” before reaching the retina and, as a consequence, the myopic has difficulty seeing the objects that are far, but not those that are near . The greater the degree of myopia, the more the person has to approach the objects to see them well. Presbyopia is also a refractive error but it is not due to the genetic morphology of the eye, but to the malfunctioning of the eye due to age. On the other hand, presbyopes have difficulty seeing nearby objects, not distant ones. In addition, while myopia usually appears in childhood and evolves to stabilize (around 20 years), presbyopia appears after 40 years.
Have you noticed that more and more people are walking down the street wearing glasses? It is not a fashion or that medicine has advanced much, but also, we do not usually take care of our sight too much.
Find out in this article how to have healthy eyes and avoid not only wearing glasses, but also more serious problems in the future. Of course, everyone can do what they want, with their body and their habits, but at least you have to be aware of the dangers of not caring or paying attention to the health of our eyes.
Beyond drinking carrot juice because of its high content of vitamin A (I remember that my grandfather always told me about the carrot’s goodness for the eyes “or have you ever seen any rabbits wearing glasses?”, I was joking) .
The truth is that, for your eyes to be healthier, you have to consume more of this vitamin, which prevents and fights several infections, but also helps to reduce the optic nerve fatigue, something very common today, since we force Your eyes constantly being in front of the screen of the computer, the mobile, the tablet or the television.
There is also a list of natural remedies that can help you improve eye health, one of the most important senses we have.
As a first step, you have to know that the eyes are an extension of your nervous system, therefore, you have to feed yourself better, reduce stress and rest enough to keep them healthy.
Some tips that can help you are:
- Consume foods that are rich in minerals such as fruits, seaweeds and vegetables. Keep oxygenation of the eyes by exercising or breathing in a conscious, slow and deep.
- Practice a relaxing activity for The nerves like yoga or taichi, that help you to contact with your deepest being and to calm all the systems. In addition to having problems to see well and have prescribed glasses, imbalances at organic level and in relation to your bad habits or lack of eye care can bring the many consequences.
Both terms are synonyms; although ” tired view ” is more colloquial and ” presbyopia ” more technical. Frequently, the “tired sight” is confused with “visual fatigue” . Visual fatigue is a consequence of having made an excessive accommodating effort associated with either an activity involving near vision, such as reading in poor light or spending much time working with the computer, or an activity that requires constant changes of focus near-far, like driving. Visual fatigue, in addition to visual difficulties, causes discomfort in the eyes: tearing, itching, redness, gritty sensation, etc. Thus, while visual fatigue disappears when the eyes relax and allow time for the activity that has fatigued them, the tired eye is chronic . Once presbyopia is manifested, episodes of visual fatigue are more frequen
IS PRESBYOPIA REVERSIBLE?
Presbyopia continues throughout our life in a natural way. It is a process associated with aging of the eye and loss of elasticity of the lens. Presbyopia is not a reversible process. Currently there are surgical options that compensate for presbyopia: intracorneal lenses, intraocular lenses ..
In the first stages of presbyopia, when graduation is not fully structured, and due to overactivity throughout the day, it can be noticed more pronounced at night.
CONVERGENT OR DIVERGENT LENSES FOR PRESBYOPIA?
Presbyopia is compensated by positive lenses that add to graduation from afar. Converging lenses are positive so presbyopia is compensated by positive lenses although the final close-up may be positive or negative depending on the graduation we have at a distance.
More than a risk is a natural process that affects or will affect all people at a certain point in our lives. Over the years, the lens of the eye loses its flexibility so that it can not focus sharply on nearby objects.
NATURAL CURE FOR PRESBYOPIA. EXISTS?
There is no natural cure for presbyopia, understanding that it is not a disease. It is a natural way of aging the eye that affects anyone.
PROGRESSIVES FOR ASTIGMATISM. CAN I WEAR BIFOCALS OR MONOFOCAL?
Progressive lenses allow you to meet different visual needs on a single lens. If our activity requires focusing at different distances, the best option is progressive lenses. In your nearest ophthalmological center, you can evaluate the best visual solution for each situation.
Presbyopia can not be prevented or delayed because it is not a disease, but a natural process. Presbyopia, also known as a tired eye, is a visual defect associated with the age by which the lens loses elasticity so that the eye sees reduced its ability to adapt and therefore to see up close. Presbyopia, being related to an age-related degenerative process, can not be prevented.
THIN PROGRESSIVES, WHAT THICKNESS HAS A PROGRESSIVE LENS?
There are several parameters that must be taken into account when defining and evaluating the thickness of a progressive lens such as the graduation of the user, matter with which the lens is manufactured as well as the index of refraction of the same. Also the shape of the chosen frame and the nasopupilar distances ( the nasopupilar distance is the distance between the axis of symmetry of the face and the center of the pupil) of the user .
ARE ALL PROGRESSIVE LENSES THE SAME?
No. There are more advanced and more basic correction products. Progressive lenses of old traditional generation solve your visual needs in a very generic and inaccurate way.
80% of the information we receive is through the eyes, which is why it is worth using a more advanced and complete product.
No. Adapting to progressive lenses is usually quick. An important factor is the quality of the design you choose.
SINCE I HAVE A TIRED EYE, GRADUATION INCREASES WITH EACH REVISION, WILL I HAVE TO CHANGE MY GLASSES EVERY 2 YEARS?
Between 40-70 years of age, there is a progressive loss of ability to focus closely.
The normal thing is that this forces us to modify the graduation from time to time.
In any case, these changes will depend on the needs of your daily activity, but the value of presbyopia always comes to stabilize.
HOW OFTEN SHOULD VISION CHECKUPS BE DONE?
In children and until the age of 15, it will depend on the type of graduation and it is best to follow the indications of your specialist.
As a general rule the revisions should not oscillate between 6 months and 1 year.
From the age of 15, the ideal is an annual review.
