Sunglasses SUN SMITH for Eyes with Retinitis Pigmentosa, Glaucoma or Cataract

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. 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. 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.)

While sunglasses don't cure RP, they play an important role in protecting the eyes from harmful light and potentially improving comfort and visual function for individuals living with this condition. UV protection is crucial for managing the condition. Bright sunlight can exacerbate the effects of retinitis pigmentosa, potentially speeding up retinal damage.

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 and absorb specific wavelengths of light, protecting light-sensitive retinal receptors.

Different tints 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 527-585 nm (blue light).

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!

Classic range:
Perfect 527 (retinitis pigmentosa, glaucoma or/and cataract), Conquer 550 (retinitis pigmentosa), Complex 585 (retinitis pigmentosa and extreme photophobia); 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 527 (retinitis pigmentosa, glaucoma or/and cataract) tints now available in different solar categories!

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:
