Problems with light and glare can endanger any driver. Uncontrolled glare may mask oncoming traffic and limit the ability to see signs and brake lights. Glare control is one of the most critical issues that must be dealt with for safe driving. Not controlling glare can lead to failure of an otherwise good driving candidate or make the driver less safe on the road.
Patients with high myopia may vary on their light sensitivity. Some conditions require much more stringent control of light and glare. Safe driving requires a combination of careful control of glare and anticipation of potential glare problems.
Glare Problems in Driving
Photostress or Poor Glare Recover: When the energy of light bleaches out the chemicals in the retina, a temporary decrease in vision may occur. We all experience a brief form of this when we have a flash picture taken and notice a temporary spot in our vision. Patients with central retinal disorders like macular degeneration and Histoplasmosis may bleach-out severely and not quickly recover to their base vision
Discomfort Glare or Photophobia: Discomfort glare is the visual discomfort or pain caused by very bright light such as direct sunlight or bright lamps. It can vary from mild annoyance to overwhelming pain.
Disability glare: Disability glare is the situation where vision is impaired by excessive dazzle from a bright light source or reflection such as light reflecting from a glossy surface or from water. The degree of this impairment can vary from minor low contrast veiling glare across the vision to severe temporarily blinding glare.
Proper Sunglasses for driving
Proper sunglasses are helpful for most drivers, but critical for low vision (high myopia with high Visual Acuity 6/18 or more) patients who are often more easily impaired by glare. Your Optometrist at Malaya Optical in Damansara Uptown can determine the proper type of filter. The color and properties of the filter are important.
In fitting the Rubig Fit Over Sunglasses we prescribe these filters for the patient to put over their current prescription eyeglasses. The Rubig Fitover is a High Defination Polarized Sunglasses with UV protection, which helps some patients on overcast, foggy or rainy days and light reduction for the patient on their needs in different situations.
