I doubt dressing up for a trip to the mall on a sunny saturday afternoon will ever be complete without spotting a nice fancy sunglasses or sunshades as we call it in this part of the world. They come in different shapes, sizes and colors. I personally prefer the brown ones to the colorful types.
It turns out your sunshades are more than just some fashion statement. Sunshades actually protect your eyes from a variety of health problems ranging from sun burns, cataracts and skin cancer.
A few of the dangers associated with excessive exposure to UV radiation includes,formation of wrinkles and age spots, skin cancers, thickening of the conjuctiva (pinguecula), macular degeneration, cataracts e.t.c.
How to protect them
UV: Look for a label that says 99 or 100 % UV absorption or UV400. This means the glasses block wavelengths shorter then 400nm.
Polarized: Don’t confuse polarized for added sun protection. It only implies they cut the glare from horizontal surfaces, allowing for crispier, clearer vision, particularly while driving.
Lens colour: The darkest pair doesn’t imply the best protection. Many shades can work well including grey, green, brown, yellow, or rose. It’s just individual preference.
Lens material: A quality pair of sunglasses will have optically ground lenses with little distortion. Cheaper varieties are usually made out of pressed plastics. NOTE: when trying them on, turn your eyes left and then right while you are looking through the lenses to determine if there's any distortion.
Frames: Over-sized glasses are more than fashion statements. They are good for eye protection as well. Big frames or a wrap around style shields more UV , preventing rays from coming in at the sides. wrap around glasses can also help to cut down on dry eye by preventing evaporation of the eye's natural tear film.
