Types of Vision Defects

Myopia: 

Myopia is the most common visual defect. People with myopia have poor far vision; objects in the distance appear blurred. Conversely, they have very good near vision.

Correcting myopia:

Myopia is corrected with concave lenses that are thicker at the edges than at the centre. The thickness of the lens increases with the level of correction. It can be limited by choosing thin lenses.

Our advice for your visual defect

Your myopia can be perfectly corrected with Nikon aspheric concave lenses
The choice of index depends on the level of correction you need.
• medium index if you need a small or medium amount of correction (up to – 3.00 D) e.g.: indices 1.5, 1.59 or 1.6
• high index for higher levels of correction. e.g.: indices 1.67 or 1.74

 

 

Hypermetropia:

Hypermetropia is the opposite of myopia. People with hypermetropia have blurred near vision. They can see clearly but only by working to accommodate the defect, causing significant visual fatigue. Conversely, their far vision is clear.

Correcting hypermetropia:

Hypermetropia can be perfectly corrected with convex lenses, which are thicker in the centre than at the edges. The thickness of the lens increases with the level of correction. It can be limited by choosing thin lenses.


Our advice for your visual defect

Your hypermetropia can be perfectly corrected with Nikon aspheric convex lenses.
The choice of index depends on the level of correction you need.
• medium index if you need a small or medium amount of correction (up to + 2.00 D)
• high index for higher levels of correction.
For even better vision, choose the Nikon SeeMax personalised multi-aspheric lens, which offers even sharper image quality.

 

Astigmatism:

People with astigmatism have a cornea that is more oval-shaped than round, causing problems with both near and far vision. Poor perception of contrasts results in confusion when reading. Astigmatism is often combined with myopia or hypermetropia.

Correcting astigmatism:

Astigmatism is corrected with toric lenses, which vary in thickness depending on the axis. The thickness of the lens increases with the level of correction. It can be limited by choosing thin lenses.


Our advice for your visual defect

Your astigmatism can be perfectly corrected with Nikon aspheric toric lenses.
The choice of index depends on the level of correction you need.
• medium index if you need a small or medium amount of correction (up to – 2.00 D)
• high index for higher levels of correction.
For even better vision, choose the Nikon SeeMax personalised multi-aspheric lens, which offers even sharper image quality. Nikon SeeMax is particularly well suited to people with astigmatism.

 

Presbyopia:

Presbyopia appears at around the age of 45. It is due to the natural ageing of the crystalline lens, which loses its power of accommodation, so that the eye is no longer able to focus correctly. It results in increasing difficulties with seeing things close up.

Correcting presbyopia:

Presbyopia can be corrected with three different types of lens:
• single-vision lenses for near vision, to see clearly at 30 cm,
• mid-distance lenses, to see things close up and slightly further away,
• progressive lenses, to see things close up, in the middle distance and further away.
Which type of lens to choose depends on the person’s needs and any other visual defects in addition to their presbyopia.

Our advice for your visual defect

Depending on your needs, your presbyopia can be corrected with:
• Nikon aspheric single vision lenses,
• Nikon Soltes mid-distance lenses, which offer broad near vision and comfortable mid-distance vision, ideal for working in an office or on a computer screen,
• Nikon Presio and SeeMax Presio progressive lenses, for clear vision at any distance.
