More Than Mere Fashion: Norwood LASIK Professionals Helping You Choose the Right Glasses

It is very difficult to avoid the sun, but the Eye Care Specialist at the Norwood LASIK clinic want you to remember how important it is to protect your eyes from harmful UV rays, especially in these summer months. There are many things you can do to help your eyes, but none more so than sunglasses, one of the most useful and stylish fashion accessories available. Sunglasses are great for protecting our eyes from ultra-violet radiation that could lead to the development of cataracts, early macular degeneration and, believe it or not, skin cancers—on the skin around the eyelids—like basal cell carcinoma, squamous cell carcinoma, and melanoma. But before buying a new set of shades, there are a few things you should consider.


Different lenses for different situations


Our Norwood LASIK professionals consider any tinted glasses that have the capacity to filter UV rays to be a good thing, but certain lenses are better equipped to handle different situations and environments than others. Some sunglasses are more effective in higher altitudes to prevent snow blindness, while others fit a more tropical climate like South America. For example, dark glasses are particularly useful for patients who have undergone cataract surgery, LASIK surgery, and those who chronically suffer from ailments like conjunctivitis, uveitis, and any other disease making them susceptible to light sensitivity.


Blue-blocking lenses—which are a popular choice among skiers, hunter, seamen and pilots—have the practical use of heightening contrast. Polarized and mirror-coated lenses are worn more by people who play water and snow sports because they cut down on reflected glare and limit the amount of light entering their eyes. Truck drivers typically use gradient lenses, as they shield eyes from overhead light through the bottom half of the lens so to see the dashboard clearly, while photo chromatic lenses adjust their tint levels based on the amount of UV light.


It’s clear that sunglasses can be used for all purposes. Even large polluted cities, like Beijing, sunglasses have the dual purpose of protecting eyes against external allergens and carbon particles from smog and exhaust pipes.

Dark-colored lens does not guarantee UV protection


Sometimes it is difficult to tell whether you’re receiving adequate protection from your glasses because the color and degree of darkness of the lenses do not accurately indicate their ability to block UV light. Light-colored lenses can even be misleading, and offer 100% UV protection.


Dr. Ghanshyam Singh, the assistant director and head of L.V. Prasad Eye Optical agrees: “It has been found that people wearing dark-colored lenses and think that their eyes are protected but that is wrong. It often proves worse for the eye as the pupils get dilated as they are exposed to harmful rays of the sun. People must check for the UV protection ability of the lenses before buying sunglasses.”


The Eye Care Specialist at the Norwood LASIK clinic would recommend a 70% lens density and absorption value. Grey-grey or grey-green are particularly good lenses, able to provide color transmission throughout the visual spectrum.


Sunglasses are only for the outdoors


In the course of our fast paced livers, it is easy to forget to throw on a pair of glasses before leaving the house. It’s important to remember to protect your eyes, but especially so for people who work for long hours outdoors and who are exposed to a large amount of UV rays. Those who are close to the equator are at a higher risk of developing eye disease, as well, because of the higher elevation living conditions and the constant exposure to the mid-day sun. During the summer months, while outdoors, the level of UV radiation is three times higher than during winter. One the flipside, sunglasses should not be worn indoors as the dark glass lenses adapt the vision by increasing photo sensitivity of the eyes. The darker the glasses the more light-sensitive your eyes get. Indoor use thus can also cause eye strain.


Eye damage is slow, but accumulates over a person’s lifetime causing a myriad of different eye diseases. The damage to the eye is not visible in the first decade of life; so Norwood LASIK doctors suggest that practicing the right methods of protection must start at childhood.
