Sunglasses are an easy solution that makes life more comfortable when outdoors, while also providing critical protection from the sun’s damaging ultraviolet (UV) rays. Long-term exposure to UV rays can sometimes contribute to cataracts (clouding of the lens) and macular degeneration (breakdown of the macula).The key to enjoying the sun is a pair of sunglasses that are qood quality, stylish and reasonably priced. That’s why here at Samantha Parker Optometrist , we not only keep a range of sunglasses to suit, but can also create prescription sunglasses. We recommend Nike sunglasses as well as Dakota and Storm.
Whether you are playing a round of golf or spending a long day on the cricket field, there are a host of sports sunglasses to protect your eyes. Top companies have spent millions developing sports sunglasses with extra tough frames and lenses to cope with outdoor sports such as tennis, cricket and golf. Avoid metal frames which can break, and look for polycarbonate.
Varying light conditions and glare can cause drowsiness and reduce concentration. Because the windscreen will take away 40% of the UV risk, this will reduce the effectiveness of photochromic lenses (which darken in sunlight). Polarising lenses will help as they are specially made to reduce reflective glare off flat road surfaces and relax the eyes.
Also, make sure the sunglasses are in the filter category range of 0-3. A lens carrying a filter category of 4 will be too dark for safe driving. Never wear sunglasses when driving in poor light.
Whether you’re windsurfing in Wales or jetskiing in the Bahamas, on a sunny day it is best to wear polarised lenses that reduce reflective glare from the water surface, while polycarbonate material allows lenses to be lightweight and safe and which will not shatter on impact. Wraparound styles help keep out peripheral glare and spray, and when fitted in nylon or other polyamide materials provide excellent safety.
Determine which special features you need or want. Like cars, sunglasses often have a variety of “extras” from which to choose:
- Polarised. Polarised lenses cut reflected glare—when sunlight bounces off smooth surfaces like pavement or water. These can be especially helpful when driving, boating or out in the snow.
- Photochromic. This is a type of lens that automatically darkens in bright light and becomes lighter in low light. Although photochromic lenses may be good UV-absorbent sunglasses (again, the label must specify this), it can take a few minutes for them to adjust to different light conditions.
- Impact resistant. Polycarbonate, used in many sports sunglasses, is even more impact resistant than regular plastic, but scratches easily. If you buy polycarbonate lenses, look for ones with scratch-resistant coatings.
