Lesa Sunglasses or Clips for Cataract, Glaucoma, AMD and Retinitis Pigmentosa

Principle

To address the needs of people with various visual impairments, such as colour vision defects and severe light sensitivity in patients with glaucoma, cataract, age related macular degeneration, pigmentary retinopathy, diabetic retinopathy, etc. LESA France offers a full range of special absorptive therapeutic filters developed specifically for Low Vision applications. (Age related macular degeneration is a genetically transmissible disease and is responsible for an increasing number of cases of low vision. Condition affects the macular region, the area which enables us to see objects in central vision. A slight visual discomfort at first, more or less then gradually the lesion increases to form a central spot to form a central spot -scotoma. Near vision rapidly becomes difficult. Pigmentary retinopathy is a genetic disease that attacks the photoreceptor cells of the retina. The field of vision becomes tubular - central vision only. Retinopathy gradually leads to blindness. Glaucoma is often associated with high intraocular pressure inside the eye, slowly destroying the optic nerve. This gradually leads to a deterioration of the peripheral visual field. Often painless, it can lead to permanent blindness if left untreated. Diabetes leads to the appearance of lesions on the retina. This is known as diabetic retinopathy. It leads to a progressive loss in visual acuity. A cataract is a clouding of the crystalline lens. A sort of fog is created in front of the eye. The decline in visual acuity is progressive.)

UV light is harmful to the eye, but it has been shown that blue light also has a harmful effect. These are the short, energetic waves of daylight. When it enters the eye, its diffusion creates a kind of deformation of the image on the retina, leading to a reduction in contrast. The purpose of the filters is to suppress this light to make vision more comfortable. Sensitivity to glare will be reduced. There is an increase in contrast and acuity, and therefore comfort. The filter will select the wavelengths that can enter the eye.

Different tints are available, filtering wavelengths from 450nm to 550nm.
All our filters are 100% anti-UV. 

The glasses are used as standard non-refractive sunglasses and are available in different sun protection categories from 1 (indoor, cloudy weather) to 3-4 (outdoor, sunny) and tints. Category 4 - not suitable for driving!

Pastel tones:

Shades that are very popular for indoor use.

Classic range:
Excel 450, Lumio 500, Mysteris 511, Perfect 527, Conquer 550, Complex 585; all these shades cut the blue light diffusing the eye, and actively help actively help to improve vision for the visually impaired.

New outdoor models: 
The classic 450 and 527 now available in different solar categories!

If you need vision correction, you can use a clip-on that is used over your existing prescription glasses. The glasses are also suitable for all types of prescription lenses and for wearing with a variety of prescription lenses with or without therapeutic filters.
