Definitions

  • the present invention relates to optical lenses and in particular lenses through which incident glare is reduced, for example as used for night driving.
  • vision research data shows that ambient light intensity changes are associated with three distinct regions of visual acuity. See Figure 1. At high light intensities, the visual acuity is high and essentially independent of luminance. This is photopic vision where the cones are the primary detectors. At very low light intensities, visual acuity is reduced by a factor of about ten, also essentially independent of luminance. This is scotopic vision, when the rods are our primary detectors. In between, visual acuity changes quickly as luminance changes and both rods and cones are used for detecting images (mesopic vision). The conditions at which visual acuity begins to drop correspond to late afternoon, continuing through dusk and twilight to reach the lower plateau at conditions akin to a clear moonlit night.
  • the pupil diameter typically enlarges in a natural response.
  • this is dependent on age. Older people show much less pupil reaction to light level changes and consequently it must be inferred, are thereby disadvantaged more by loss of illuminant intensity for example in fading sunlight. Further as opacities in the orbital globe also increase with age, these may also contribute to greater glare susceptibility with age For older people to- have the same efficiency in detecting visible objects, the contrast must be enhanced. The required "contrast multiplier" increases with age and is exaggerated by diminished background intensity, as shown in Figure 2.
  • BCD luminant intensity
  • BCD Basal between Comfort and Discomfort
  • It represents the threshold for discomfort and is very much observer dependent. Increasing size of the glare source increases the brightness needed to produce discomfort. For example a sunlight sky would need to reach an extreme luminant intensity of approximately 100,000 cd/m 2 to be a source of discomfort. The glare source brightness needed to cause discomfort decreases as the background lumination decreases. Also the threshold for discomfort decreases as individuals age, according to the formula
  • a ten year old may not experience discomfort on a snow field whereas a 70 year old may experience significant discomfort on a clear day in the park. Persons may also experience discomfort in high artificial illuminance situations, such as in a theatre or sports field, where the glare source is significant and may be of varied spectral distribution.
  • some modification is needed to reduce discomfort glare (glare caused by bright sources of light).
  • some modification would be desirable to improve visual acuity for example in late afternoon or evening, particularly for older wearers who may suffer from night myopia.
  • a glare reducing optical lens including an optical lens element of glass or polymeric material; a reflective and/or absorbing coating or material on/in at least a portion of the periphery of the front or rear surface of the ophthalmic lens element; and optionally an anti-reflective coating on at least a portion of the front and/or rear surface of the optical lens element.
  • the glare reducing optical lens has been found to positively reduce the level of discomfort associated with human glare response.
  • the glare reducing optical lens according to the present invention may further minimise any loss of visual acuity when exposed to glare and further produce an improved recovery of visual acuity after glare is removed.
  • the optical lens element according to this aspect of the present invention may be piano or may include a front and/or rear surface capable of forming a prescription (Rx) surface
  • optical lens element as used herein, we mean an optical lens, ophthalmic lens, semi-finished lens or lens wafer which may be utilised in the formation of an optical lens product.
  • the optical lens may be a piano lens with or without decentration, or a lens of negative or positive refractive power.
  • a piano lens or lens of negative power with respect to the wearer's distance prescription (Rx) is preferred.
  • An ophthalmic lens element of approximately -0.25 to -0.34 Dioptre or greater, more preferably -0.50 D or greater may be used. Applicants have found that a correction of approximately -0.50 D may reduce or eliminate night myopia when experiencing illumination. A correction of approximately -0.25 to -0.34 D may in turn reduce or eliminate the visual dysfunction associated with, mesopic vision at twilight times for example around dawn or dusk.
  • the optical lens element may be of the wrap-around or single element shield (unitary lens) type or decentred piano or corrective lens type, for example as described in copending Australian Provisional Patent Applications PN 8806 “Sunglass Lenses” and PO 4137 "Improved Single Vision Lenses” to Applicants, the entire disclosures of which are incorporated herein by reference.
  • the binocular field of vision of a human is approximately 60° in all directions, limited by the brows, the nose and the cheeks. In the temporal region, monocular vision reaches out to approximately 100°.
  • the field of central vision of each eye is a cone of approximately 30° angle to the line of sight.
  • Glare sensitivity in our peripheral vision may change significantly for a given angle off axis, depending on whether one is viewing towards the brows (superiorly) or the temples (temporally).
  • the main source of glare in night driving is direct or reflected light from the head lamps of other vehicles. This light may enter the eye directly or through spectacles, in which case it is within the central field or cone of vision. See Figure 5.
  • Light impinging from in front of the driver is distracting, but persists only while the vehicle is approaching.
  • Other light enters the temporal field particularly from vehicles to the side or behind and may persist for long periods of time. Its passage to the eye could be via the lens from a rear vision mirror (ray 1) or from wing mirrors, via a reflection from the back of the spectacle lens (ray 2), or directly between the edge of the spectacle lens and the temple (ray 3).
  • the anti-reflective coating on the optical lens according to this aspect of the present invention may reduce the intensity of lens back reflections, but it cannot deal with the other two glare sources.
  • a peripheral reflective and/or absorbing coating or material as described above preferably with the lens shaped to wrap around the temple, intercepts and reduces the degree of discomfort associated with glare due to the intensity of incoming light.
  • the optical lens element includes an integral temporal extension.
  • the peripheral reflective and/or absorbing coating or material may take the form of a tint and/or mirror coating including mirror coatings reflective to a particular wavelength region of the spectrum.
  • a gradient tint is preferred.
  • the gradation may increase radially or linearly as the angle from the line of direct vision increases.
  • the tint density may vary with the nature of the intended application, but for driving may be such that the integrated visible light transmission, with respect to CIE (Commission Internationale De L'Eclairage), is not less than any minimum determined to ensure compliance with the relevant ISO standards relating to the required forward visible transmission through lenses or the transmissions allowed for peripheral detection based upon legislation relating to the presence or absence of tinted car side windows, for example llluminant C, (ILL.C) may not be less than 75%T for forward vision under some circumstances.
  • the gradation may correspond to the desired BCD contour plot.
  • the angles from which a wearer of prescription (Rx) lenses is able to collect focussed light depend on the physical aperture of their Rx lenses and the refractive power of those lenses.
  • the light from a field is substantially larger than that seen by a person not needing an Rx (emmetrope).
  • the effect can be, for example, to multiply the total intensity of light encountered by a myope compared to the emmetrope.
  • an Rx in the high plus focuses a reduced field and this lowers the total intensity brought to focus from a given field. Assume some performance targets for distance visual field:
  • the aperture provided by the anti-glare treatment needs to decrease with increasing minus Rx, and so should the average transmission through the central visual region [that is zone size and %T decrease).
  • the aperture provided within the bounds of the peripheral coating or material may generally increase as the lens power increases and/or the visual field of the optical lens element may increase, for example by utilising an optical lens element of the wrap-around type.
  • the width of the peripheral coating or material may increase as the lens power increases and/or the visual field of the optical lens element may decrease.
  • the peripheral reflective and/or absorbing coating or material on the reduced glare optical lens may extend around at least the temporal region of the lens.
  • the peripheral reflective and/or absorbing coating or material may generally surround the cone of direct vision, preferably the binocular field of vision, of the wearer.
  • the peripheral reflective and/or absorbing coating or material may include a dye or pigment metal or semi-metal selected to attenuate unwanted glare.
  • a dye or pigment composition may be selected to provide broad band absorption to attenuate unwanted glare.
  • a brown or grey tint is preferred, but blue, yellow or green tints may be used.
  • the tint should provide maximum possible visibility in night conditions while also limiting the glare.
  • the optical lens element may include a body tint or coating.
  • the body tint includes a light body ting and a peripheral tint at a higher concentration extending around at least the temporal region of the lens.
  • the body tint includes a uniform tint across substantially the entire optical lens element.
  • the body tint functions to reduce transmission of daytime UV light but such that night vision is not substantially hindered.
  • the body tint includes a photochromic treatment wherein desirably the photochromic treatment functions to reduce transmission of a substantial proportion of light during daytime conditions but such that night vision is not substantially hindered.
  • HID High Intensity Discharge
  • the tint or coating is selected to at least partially restore the spectral mix of natural daylight for objects being illuminated by incandescent light, both indoor and outdoors. It also may preferably provide simultaneously the opportunity to selectively remove intensity from the spectral distribution of incandescent glare sources and render them "white”. This achieves an optimum in visibility for both photopic and scotopic vision both of which are used in typical night driving situations while minimising total luminant intensity.
  • Figure 9 “Visual Response to Tungsten - Halogen Lamps” shows the normalised intensity spectrum for incandescent lamps and the normalised response functions for cones and rods of human eyes. From these three curves, the retinal intensity spectra may be calculated for both rods and cones. The shift to longer wavelengths for both is evident in the graphs.
  • the cones are specialised to give spatial resolution of images and adapt perhaps ten times more rapidly than do the rods to changed illumination level.
  • the rods are far more sensitive to the absolute intensity of light in darkened conditions such as outdoors at night or in dimly lit theatres. They become saturated and lose their detection facility under bright conditions. Applicants believe this to be at least part of the reason why some of the anti-glare spectacle lenses studied during this investigation produce opposing sensations to wearers at high and low glare levels.
  • the object is to provide wearer comfort over a full range of glare intensity levels.
  • Suitable transmission spectra for an anti-glare lens which functions well over a wide range of intensities will show attenuation of short wavelengths up to about 450 nm and also in the range 550 to 700 nm and optionally with a broad minimum in transmission at the yellow/red. These requirements allow the formulation of lens treatments that have pleasing cosmetic colours such as brown, grey, green and blue rather than the unattractive pure yellow used for example in prior art lenses.
  • the dye composition may include a dye material absorbing in the infrared wavelength range, preferably in the far red/near infrared range. Absorption in the region of approximately 675 nm is preferred.
  • a blue dye for example a turquoise blue dye, may be used.
  • a dye material sold under the trade designation Disperse Blue 60 has been found to be suitable.
  • dye material absorbing in the far red/near infrared range may be used
  • the dye or pigment composition may alternatively or in addition include a dye material absorbing in a wavelength range up to and including the rod sensitivity maximum (approximately 507 nm).
  • the dye material may absorb across a substantial proportion of the range of rod sensitivity, for example from deep blue to mid-green.
  • a yellow and/or UV absorbing material may be included.
  • a quinophthalone-based dye may be included.
  • the absorption pattern of such a dye may be contrasted with the absorption patterns of yellow dyes utilised in the prior art in that it provides a sharper absorption edge in the long wavelength region of the spectrum.
  • the mirror coating on the reduced glare ophthalmic lens element when present, may be of any suitable type.
  • a gradient mirror or a selective wavelength reflective mirror may be used.
  • a front and/or back surface gradient mirror may be used.
  • the mirror coating may be introduced utilising conventional techniques, for example vacuum deposition of metal film on a finished lens.
  • a chemical solution of a pristine metallic layer may be deposited on part of a casting mould and subsequently a lens is cast against that mould.
  • a metal mirror thus formed may transmit insufficient light to form any troublesome images and reflecting a soft matt finish in copper or nickel or whatever the chosen metal.
  • the peripheral reflective and/or absorbing coating or material may be solid, i.e. without gradient, or may function to produce a BCD gradient in the temporal region such that substantially increased glare tolerance is created outside the binocular field of view or it may be solid without gradient. Any gradient may extend as desired inwardly toward the line of direct vision, the BCD declining so that direct vision is substantially unaltered, acuity and visual efficiency thus being maintained for the essential tasks of driving.
  • the BCD contours may be modified to turn towards the horizon and/or on the O° to 180° axis or toward the generalised source of the glare, as illustrated in Figures 6, 7 and 8.
  • the top right quadrant represents the glare contours for normal vision at low illuminant levels.
  • On the left side is drawn a idealised shape for the outermost contour. It is bent steadily toward and is symmetric about the horizon.
  • the contour of the top right segment transforms to that of the top left quadrant if the transmission, %T, decreases smoothly with angular displacement from the 90° to 270° vertical axis (forward line of sight) as shown on the lower right side.
  • the relationship of %T and the glare contours is strict. Selection of desired optical performance characteristic defines the objective for coating and/or tint densities on the lens or shield.
  • the selection of a %T variation to suit the details of coating or tint application may be used to define the properties of the lens or shield.
  • the plot in Figure 7 corresponds to an assumed %T based on the outcome of a first design exercise. The glare contours may then be calculated directly.
  • the %T graph inserted at the lower right segment of the plot is meant to align with the angular scale of the horizon. So, this example has first decrease in transmission at approximately 30° from the line of direct vision and becomes more attenuating as the angle increases. In this example, the %T falls almost linearly and reaches a minimum value ⁇ 10% at the temporal periphery. The selection of any one contour permits the definition of the corresponding transmission profile for the lens or shield. Thus, reverse calculation using the %T profile yields the complete series of glare contours.

Subjects indicated the line on a "logMAR" Chart they could read ten seconds after the ceasing of the application of the glare source. The maximum difference between their dark adapted state and the worst acuity during the presentation of the ten glare sources was recorded, and the differences between these calculated and compared for their fully corrected or unaided visual state and compared to that achieved when the lenses were in position. Note was also taken of their best visual acuity both in their fully corrected or unaided visual state and compared again to that achieved when the lenses were in position. c) A cumulative sum statistical analysis was undertaken on the results achieved in Example 1. The results are presented in Figures 13 to 19.
