abstract = {Purpose: The aim of this study was the evaluation of different plastic optical materials and determination of their behaviour in front of the eye. The study was not for clinical screening but mainly for material determination purposes, where the contrast sensitivity function is inefficient and difficult to interpret. Methods: Thirty male and female subjects with no ocular or reported systemic abnormality were selected. Twenty-two lenses of +6.00D power, made from 8 different plastic materials following requested: specifications; were edged to round shape and decentred in order to produce a 9 ∆ prism in front of the subjects' eye. Measurements of every subject were repeated four times on Bailey-Lovie and Pelli Robson charts, for each lens used in the experiment Results: A significant decline of visual acuity in correlation to higher index plastic lenses was observed. Also we observed a similar visual acuity decline concerning aspheric design lenses, but with a little better performance than non-aspheric design lenses of the same index material. Conclusion: The hypothesis of this work was that the higher the index the more the chromatic aberration. The conclusion is that this hypothesis is quite correct. However, the measurement of visual performance is not a very easy task. The wearer may simply experience blur through the periphery of the lens without realising the cause, and therefore the symptoms described to the optician can be confusing.},

abstract = {Light plays an important role in many functions of the human body. It improves visual acuity, contrast sensitivity and colour perception while improving mood, memory and maintaining hormonal balance through the regulation of the sleep-wake cycle. The low wavelength violet-blue light in the spectrum of 390-470 nm is high energy light and has been blamed for causing damage to the retina. Many studies have looked at how blue radiation affects eye health, visual acuity and circadian rhythm, especially in relation to the placement of filters that reduce the passage of blue light into the intraocular or ocular lens. In general, blue light improves contrast sensitivity and vision in intermediate lighting conditions, affects the sleep-wake cycle through melatonin secretion, and can cause several oxidative reactions in the retina resulting in the accumulation of photo deposits. Today it is well known that the spectrum in blue light radiation creates a wide range of health problems in every category of population, from premature infants to the elderly. This blue light spectrum is contained in the white light of Light Emitting Diode (LED) lamps, "economical" and any light source, such as that which comes from smartphones, computers, and many other devices whose light is a composition of colour spectra having the most powerful spectrum in blue. Blue blocker ophthalmic lenses provide a solution to all the above.},
