The effect of optical filters on the prevention of retinal disease development and progression

Popis výsledku v původním jazyce

Short wavelingth light carries a large amount of energy that is able to interact with the pigment cells of the eye tissues. Patients with retinal disorders such as age related macular degeneration, retinopathy or other defects, short wavelengths need to be blocked. The optical media of the eye are a partial filter of UV and blue light. We can also filter the light using spectacle lenses (each lens is capable of blocking UV radiation) with different surface treatments. The conventional lens transmits light from 355 nm and reaches a maximum at 398 nm. With a higher refractive index, it can have transmittance from 395 nm and reaches a maximum at 438 nm. A spectacle lens with a special treatment against blue light transmits wavelengths from 414.5 nm and can reach a maximum at 450 nm. Care should also be taken in the choice of intraocular lens for cataract surgery. The fact that the cataract-affected lens has been a relatively effective filter of light, particularly short wavelengths, increases the risk of retinal degeneration (due to the amount of pigment deposites in the retina). A clear intraocular lens may have a maximum transmittance at 397 nm (transmitting light from 392.5 nm) and a yellowcoloured lens may have a shifted maximum up to 547 nm (transmitting light from 392 nm). Another option for blocking light is the use of corning filters.
