Just a few notes about watching a solar eclipse. A patient called me a few days ago looking for solar eclipse glasses. In my mind it is never a good idea to look in the direction of the sun. I do realize, however, that there are a lot of people who want the experience of…
Charles Bonnet Syndrome (CBS) is often regarded as a fascinating yet misunderstood occurrence associated with vision impairment. While commonly linked to those with vision loss, CBS encompasses much more than previously assumed visual hallucinations. While Charles Bonnet Syndrome (CBS) is more commonly associated with elderly individuals,…
Co Q10 and the Eye A search of ongoing clinical trials shows that there are presently 127 studies utilizing Coenzyme q10. Most all of them are in the areas of diseases of the heart, neurological disease, some psychological disorders, pregnancy, and statin users. There is some research looking at the role of decreasing levels of…
Carotenoids play an important role in safeguarding eye health and functionality, with four key players standing out: beta-carotene, vitamin A (retinol), lutein, and zeaxanthin. This diverse group of vitamin carotenoids isn’t just essential for vision; it also supports immune function, cardiovascular health, and aids in cancer prevention. The Vital Functions of Carotenoids in Eye Health…
Sunglass lenses should be able to: reduce glare and haze to provide clearer, sharper vision, enhance color definition, reduce reflections off the lenses, and most importantly, 100% UV protection. If you have read the other posts on Lens Technology, what you may have realized is that sunglasses are more than a tint used to decrease…
Decreasing light levels with a tint may give a greater level of visual comfort, but may not offer enough protection against wavelengths of light known to be harmful to the sensitive tissues of the eye. Specifically, protection from the high energy, damaging, short wavelength UV light. Lens materials such as plastic and poly carbonate have…
Tints not only vary in color, but also vary in transmissibility. The amount of light that is transmitted is the amount of light allowed to pass through the lens. The darkness of the tint does not indicate it’s capability to protect against harmful UV light. While you may think that sunglasses are just glasses with a…
Polarized lenses have a molecular structure which gives it the ability to reduce glare. Glare is light reflected and scattered off of a surface that is brighter than the surrounding light. Glare can decrease our capability to see clearly and can cause visual discomfort.
Anti-reflective coating is applied to the surface of the eyeglass lens to optimize vision by reducing glare. Ideally, it should be applied to both the front and back surface of the lens for maximum benefit. It serves several purposes:
Prism in lenses is not so much something ‘in’ the lenses, but it is actually how that lens is constructed, which is typically referred to as being ‘ground in.’ The presence of prisms will be seen as a thicker edge by the wearer. The thicker edge is where the base of the prism is located,…
