Sometimes it is really difficult to decide on the best option of vision correction. Below you can find information about which lenses are the most modern, in which case lenses are better than glasses, and what to look for when buying them.
1. When Is It Better to Replace Glasses With Lenses?
Lenses have an obvious advantage when a person is engaged in active sports or activities requiring maximum visibility since they are not limited by the frame of glasses. It is also worth giving preference to them with amblyopia and high anisometropia. If in one eye the visual acuity is -1 diopter and in the second -5, then wearing glasses will be problematic, especially for adults.
2. How Many Hours in a Row Can Lenses Be Worn Without Replacement?
Lenses are divided into hard gas-permeable and soft. The first option is used to treat ophthalmic diseases, the latter to correct refractive disorders. Obsolete hydrogel lenses can be worn no more than 8 hours a day. If you increase the wearing time, chronic hypoxia occurs and the cornea vessels increase in size.
Modern silicone hydrogel lenses can be worn up to 12-14 hours a day. Some lenses with very high oxygen permeability can be worn for longer, from a week to a month and don’t neet to be take off at night.
There is also an option of advanced moisturized silicone hydrogel lenses on the market which protects and moisturizes eyes during computer work, and active gadgets use. The third-generation lenses, in this case, give more comfort during the day and can be worn for up to 16 hours.

From this point of view, one-day lenses are considered the best but they are the most expensive. Although this option is suitable for those who mainly use glasses and wear lenses on certain occasions.
Any lens should be selected by a specialist. On a special device, the eye doctor must make sure the lens fits the cornea, then give you 10-15 minutes to assess comfort. If several options are suitable, the patient should choose what is more convenient.
When choosing glasses, you need to focus on the quality of the frame and its material. Ease of wearing, the appearance of glasses, strength, and durability will all depend on this. Particular attention should be paid to landing frames on the face, the ability to adjust the temples and nose pads.
Spectacle lenses are the main component of glasses. The quality of vision and the adequate functioning of the brain directly depend on their quality. Therefore, it is not worth buying expensive lenses but instead choose a cheaper frame.
