Visual disorders

You are Hyperopic:

This means that your vision is clear from a distance and can stay clear at the cost of an accommodative effort, which is tiring for the eyes, and when that effort loosens the vision becomes blurred from far and near.

Hyperopia is very common in children. If it is important, it causes prolonged reading fatigue and headaches at the end of the day. In some children, when hyperopia is important, it can lead to strabismus.

Anatomically your eye is shorter than the average and the sharp image of an object is formed behind the retina explaining the blurred vision. And for the image to form on the retina and be clearly perceived, convergent lenses are needed.

For the farsightedness, the contact lenses are a good means of correction. However, unlike nearsightedness, for the very farsighted, contact lenses reduce the size of the retinal image of an object compared to the glasses that increase it.

You are Astigmate:

This means that your vision is imprecise, blurred from afar or near.

Anatomically the corresponding regular astigmatism, most often a corneal curvature anomaly (flattened shape on one axis with respect to a curved shape on the opposite axis), the defect of curvature can be as internal in the lens.

Astigmatism can be associated with other visual defects such as myopia, hyperopia or presbyopia.

Astigmatism can be as irregular as:

• keratoconus,
• after a corneal transplant,
• after refractive surgery,
• after a corneal wound …

The correction of astigmatism is done by a toric lens that compensates for the defect of the cornea.

Contact lenses are a very good way to correct astigmatism:

• Regular astigmatism can be corrected with toric soft lenses or spherical or toric oxygen-permeable rigid.
• Irregular astigmatism will be corrected with rigid, oxygen-permeable lenses or scleral lenses.

You are presbyopic:

This means that reading closely is becoming more difficult and that you are forced to remove your newspaper to read it, that it is now difficult for you to watch the time or your messages on your mobile phone. By progressive loss of accommodation.

The accommodation is the ability of the eye to focus in near vision, which allows you to see sharp close objects. With age this capacity decreases by loss of flexibility of the lens which is felt towards the quarantine.

Presbyopia is early in the hyperopic and later in the myopic who removes his glasses to read closely.

This is a physiological phenomenon and convergent lenses will solve the problem. When presbyopia is associated with another visual defect, you may wear progressive eye glasses prescribed by your eye doctor.

Contact lenses correct presbyopia, associated or not with another visual defect, there are progressive soft lenses but also progressive hard lenses permeable to oxygen, you will adapt to one or the other depending on what you carry forward on your eyes.

Today we have at our disposal a large selection of progressive lenses that are more and more efficient.
