Tinted spectacles helping with glare
For a start a good reputable manufacturer should be chosen for sunglasses.
They should have a lens which has the statement that they are UV400 which means they have been coated with an anti-ultraviolet treatment which covers up to 400 nm.
The colour or tint of the lens isn’t specific to the sunglass and to some degree it depends on the eye condition that you have as to which coloured tint helps.
An amber coloured lens would generally reduce the ‘blue’ in the light entering the lens. Blue light is known to cause more glare than other colours and as such this type of lens would be known as a warm tint.
A grey coloured lens will reduce all colours of light to the same amount.
A yellow coloured lens is known to increase contrast , making dark things darker and light things lighter – it is often preferred by people with Macular degeneration and cataracts.
