Prescription Glasses Sunglasses SUN SMITH for Optic Nerve Atrophy or/and Age Related Macular Degeneration, Diabetic Retinopathy

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 filters developed specifically for low vision applications. Age related macular degeneration or AMD 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. 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. 

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. In addition, optic atrophy, a consequence of damage to the optic nerve, can reduce contrast sensitivity and make it harder for the eyes to adapt to varying light levels. The purpose of the filters is to suppress the spectrum of UV and blue light to make vision more comfortable by reducing sensitivity to glare and increasing contrast vision and acuity. The filter will select the wavelengths that can enter the eye.

Different tints for cataract are available, providing improved contrast sensitivity and enhanced eye protection from harmful light by filtering UV until 400 nm and some visible spectrum wavelengths from 400 nm to 450-500 nm.

You can use sunglasses as standard non-refractive sunglasses 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:

Softness and lightness with pastel colours such as 450C0 (AMD, DR or optic nerve atrophy). Shades that are very popular for indoor use.

Classic range:

Excel 450 (AMD, DR or optic nerve atrophy), Lumio 500 (AMD, DR or optic nerve atrophy); all these shades cut the blue light diffusing the eye, and actively help to improve vision for the visually impaired.

New outdoor models: 

The classic 450 (AMD, DR or optic nerve atrophy) tint now available in different solar categories!

Filter category: short-wavelength filtering (SWF) glasses

Origin: France

Certification: CE

If your vision requires refraction correction, other options for purchase are available (1) absorptive clip-ons over your existing prescription glasses, or (2) order absorptive filter glasses with prescription. These glasses are suitable for all types of prescription lenses with or without filters. If you would like to order the glasses with prescription, please order additionally your ophthalmic prescription lenses using the links below:

Order low prescription lenses (0.25D - 2.00D)

Order medium prescription lenses (2.25D - 4.75D)

Please note, that online order with prescription is not available for children, high prescriptions (above -5.00D), high face asymmetry, squint, bifocal or progressive lenses. If you have mentioned above conditions, or don't have the prescription or need to update it, you can book a clinical appointment for your eye test with an optometrist using the link below:
