Good morning....all glases are made for improving your vision....important thing is that you are using the correct refraction. There are many type of lenses available in market....anti-glare, blue cut, etc. Their main aim is to improve your visual quality. They stop the reflected and bad light to go into your eye and hence improve clarity. If you use laptops and tablets and mobiles for more than and hour in a day ..... The blue cut lenses will help to keep your eye calm and relaxed. As far as company is concerned...any good brand like crizal or equivalent is f9.
Next Steps
make sure you get your eye tested by an ophthalmologist as having a minus 2 number your retina needs to be examined atleast once a year along with dilated refraction.
